This RISC-V ACLINT specification [1] defines a set of memory mapped
devices which provide inter-processor interrupts (IPI) and timer
functionalities for each HART on a multi-HART RISC-V platform.
The RISC-V ACLINT specification is defined to be backward compatible
with the SiFive CLINT specification, however the device tree binding
is a new one. This change updates the sifive clint timer driver to
support ACLINT mtimer device, using a per-driver data field to hold
the mtimer offset to the base address encoded in the mtimer node.

StarFive VisionFive 2 has two versions, 1.2A and 1.3B, each version of
DDR capacity includes 2G/4G/8G, a DT can not support multiple
capacities, so the capacity size information is recorded to EEPROM, when
DDR initialization required capacity size information is read from
EEPROM.
If there is no information in EEPROM, it is initialized with the default
size defined in DT.

Before this change the FR_TXFF (Transmit FIFO full) bit (5 in
HW_UARTDBG_FR) has been used to assess if there is still data pending
to be sent via UART.
This approach is problematic, as it may happen that serial is in the
middle of transmission (so the TX FIFO is NOT full anymore) and this
test returns true infinitely. As a result, for example in _serial_flush()
DM serial function we are locked in endless while().
The fix here is to test explicitly if the TX FIFO is empty.

The support for #address-cells=2 has a loophole: if the reg is actually 0,
but the #address-cells is actually 1, like in such case below:
syscon {
#address-cells = <1>;
phy {
reg = <0 0x10>;
};
};
then the second u32 of the 'reg' is the size, not the address.
The code should check for the parent's #address-cells value, and not
assume that if the first u32 is 0, then the #address-cells is 2, and the
reg property is something like
reg = <0 0xff00 0x10>;
Fixed this by looking for the #address-cells value and retrieving the
reg address only if this is ==2.
To avoid breaking anything I also kept the check `if reg==0` as some DT's
may have a wrong #address-cells as parent and even if this commit is
correct, it might break the existing wrong device-trees.

The Xilinx ZynqMP SoC has a hardened display pipeline named DisplayPort
Subsystem. It includes a buffer manager, blender, an audio mixer and a
DisplayPort source controller (transmitter). The DisplayPort controller can
source data from memory (non-live input) or the stream (live input). The
DisplayPort controller is responsible for managing the link and physical
layer functionality. The controller packs audio/video data into transfer
units and sends them over the main link. The link rate and lane counts can
be selected based on the application bandwidth requirements. The
DisplayPort pipeline consists of the DisplayPort direct memory access (DMA)
for fetching data from memory. The DisplayPort DMA controller (DPDMA)
supports up to six input channels as non-live input.
This driver supports the DisplayPort Subsystem and implements
1)640x480 resolution
2)RGBA8888 32bpp format
3)DPDMA channel 3 for Graphics
4)Non-live input
5)Fixed 5.4G link rate

This clock doesn't seem needed but appears in a phandle list used by
ehci-generic.c to bulk enable it. The phandle list comes from linux,
where it is needed for suspend/resume to work [1].
My tests give the same results with or without this patch, but Marek
Vasut found it weird to declare an empty clk_ops [2].
So I adapted the code from linux 6.1-rc8 so that it hopefully works
if it ever has some user. For now, without real use, it seems to
at least not give any errors when called.

arch/arm/dts/rk3399.dtsi has a node
usb_host0_ehci: usb@fe380000 {
compatible = "generic-ehci";
with clocks:
clocks = <&cru HCLK_HOST0>, <&cru HCLK_HOST0_ARB>,
<&u2phy0>;
The first 2 refer to nodes with class UCLASS_CLK, but &u2phy0
has class UCLASS_PHY.
u2phy0: usb2phy@e450 {
compatible = "rockchip,rk3399-usb2phy";
Since clk_get_bulk() only looks for devices with UCLASS_CLK,
it fails with -ENODEV and then ehci_usb_probe() aborts.
The consequence is peripherals connected to a USB 2 port (e.g. in a
Rock Pi 4 the white port, nearer the edge) not being detected.
They're detected if CONFIG_USB_OHCI_GENERIC is selected in Kconfig,
because ohci_usb_probe() does not abort when one clk_get_by_index()
fails, but then they work in USB 1 mode.
rk3399.dtsi comes from linux and the u2phy0 was added[1] to the clock
list in:
commit b5d1c57299734f5b54035ef2e61706b83041f20c
Author: William wu <wulf@rock-chips.com>

arm64: dts: rockchip: add u2phy clock for ehci and ohci of rk3399
We found that the suspend process was blocked when it run into
ehci/ohci module due to clk-480m of usb2-phy was disabled.
[...]
Suspend concerns don't apply to U-Boot, and the problem with U-Boot
failing to probe EHCI doesn't apply to linux, because in linux
rockchip_usb2phy_clk480m_register makes u2phy0 a proper clock provider
when called by rockchip_usb2phy_probe().
So I can think of a few alternative solutions:
1- Change ehci_usb_probe() to make it more similar to
ohci_usb_probe(), and survive failure to get one clock. Looks a
little harder, and I don't know whether it could break something if
it ignored a clock that was important for something else than
suspend.
2- Change rk3399.dtsi effectively reverting the linux commit
b5d1c57299734f5b54035ef2e61706b83041f20c. This dealigns the .dtsi
from linux and seems fragile at the next synchronisation.
3- Change the clock list in rk3399-u-boot.dtsi or somewhere else.
This survives .dts* sync but may survive "too much" and miss some
change from linux that we might want.
4- Enable CONFIG_USB_OHCI_GENERIC and use the ports in USB 1 mode.
This would need to be made for all boards using rk3399. In a
simple test reading one file from USB storage it gave 769.5 KiB/s
instead of 20.5 MiB/s with solution 2.
5- Trying to replicate linux and have usb2phy somehow provide a clk,
or have a separate clock device for usb2phy in addition to the phy
device.
This patch tries to implement option 5 as Marek Vasut requested in
December 5th. Options 1 and 3 didn't get through [2][3].
It just registers usb2phy as a clock driver (device_bind_driver()
didn't work but device_bind_driver_to_node() did), without any
specific operations, so that ehci-generic.c finds it and is happy. It
worked in my tests on a Rock Pi 4 B+ (rk3399).

According to the dm_serial_ops documentation, pending() should:

And:
> It is acceptable to return 1 if an indeterminant number

With the current implementation, we have:
* FIFO is full -> pending() returns 0
* FIFO is partially used -> pending() returns 1
* FIFO is empty -> pending() returns 1
This is not the same as what the documentation requires.
Moreover, since [1], arm reset now flushes all console devices
(including serial) before the cpu gets reset.
Because of the flawed logic:
=> reset # user calls reset
flush() is called
_serial_flush() is called
ops->pending(dev, false) # never returns false
# board hangs indefinitely without resetting.
Fix it by using AML_UART_TX_EMPTY instead of AML_UART_TX_FULL.

In the current implementation, in case of I2C arbitration lost, a retry is
attempted; the message counter and pointer are reset to the original values
and the I2C xfer process is restart from the beginning.
However the message counter and message pointer are respectively
decremented and incremented by one before attempting any transfer, causing
the 1st transfer not to be actually retried (in case of a single transfer,
nothing is actually retried at all).
This patch fixes this: in case of retry, the 1st transfer is also retried.

As per [1], dfu_alt_info is mentioned to be as semicolon separated
string of information on each alternate and the parsing logic in
the dfu.c is based on this.
Typically, the dfu_alt_info_* is defined in .h files as preprocessor
macros with 'alt' info separated by semicolon.
But when dfu_alt_info_* is added in the environment files(.env)
the script at "scripts/env2string.awk" converts a newline to space.
Thus adding a space character after semicolon. This results in
incorrect parsing in dfu.c which is based on the information that
'alt' info are only semicolon separated.
One option is to add dfu_alt_info_* variable in .env in single line.
But there is possiblity for it to exceed the line length limit.
So update the parsing logic to remove leading space characters
before adding to the dfu list.

The current DT bindings for the rk3588 clock use a different ID than the
one that is supposed to be written to the hardware registers.
Thus, we cannot use directly the id provided in the phandle, but rather
use a lookup table to correctly setup the hardware.
This approach has been implemented already in Linux, by commit :
f1c506d152ff ("clk: rockchip: add clock controller for the RK3588")
Hence, implement a similar approach using the lookup table, and adapt
the existing reset driver to work with SoCs using lookup table.
The file rst-rk3588.c has been copied as much as possible from Linux.
Adapt the clk rk3588 driver as well to bind the reset driver with the
lookup table.

- Misc fixes for drivers;
The CRU is being probed with a default set of assigned clocks, which
are not implemented in the driver at all.
Hence, when clk_set_defaults is called, it fails with ENOENT.
This would not be a problem, as the CRU still handles all the required
clocks, and the assigned clocks are default configs which are preprogrammed
or not required for Uboot operations.
However, the rockchip reset driver is being bound by the same DT node
as CRU, as the reset driver has no DT node.
But, when probing the reset node, it will call again the clk_set_defaults
for the CRU node, and failing because of missing those specific clocks
in the rk3588 clock driver.
To avoid this, simply implement a basic set/get that will just return
success and the default corresponding rate for the required assigned clocks.
As those clocks were not supported in Uboot, not required for Uboot
operations, there is no need to do any different kind of initialization.

Implement a resource release mechanism on failing probe.
Without this, a strange situation can happen e.g. when init port fails,
or attempting to get the PHY fails, because the gpios have been
requested first, and if the user tries to do 'pci enum' again, the
driver will fail with 'can't find reset gpios' even if the gpios are
there, just because they were blocked by a previous probe attempt.
It is only natural to release the acquired resources if the probe fails,
just for consistency if nothing else.
This way on subsequent probe attempts, the user will get the same error
message, and not something different that doesn't make sense.

In the process of adopting CONFIG_DM_ETH on the DPAA2 based platforms,
interfaces which were previously defined as "xgmii" were transitioned to
be defined as "xfi" in the DTS.
See the commit below for reference:
commit 87274918f2 ("arm: dts: ls2088ardb: add DPMAC and PHY nodes")
Then Vladimir's commit replaced all occurrences of "xfi" with
"10gbase-r" in an effort to make U-Boot work with the same device tree
as Linux.
commit 77b11f7604 ("net: replace the "xfi" phy-mode with "10gbase-r"")
These changes to the phy_interface_t of an Ethernet port meant that the
mc_fixup_mac_addrs() function was no longer capable to properly fixup
the MAC addresses. The problem arises from the fact that the hardcoded
information about an interface (wriop_get_enet_if()) was no longer
matching any actual device.
For example, the function tried to search for "DPMAC1@xgmii1" by name
using eth_get_dev_by_name() when only "DPMAC1@10gbase-r" was available.
This function removes the need to rely on the hardcoded information by
iterating through all the UCLASS_ETH devices which are DPAA2 and request
a fixup for each of them.

Commit dafe0fbfb0 ("pinctrl: mediatek: rewrite mtk_pinconf_set and
related functions") changed the logic deciding to set R0 and R1
registers for V1 devices.
Before:
/* Also set PUPD/R0/R1 if the pin has them */
err = mtk_hw_set_value(dev, pin, PINCTRL_PIN_REG_PUPD, !pullup);
if (err != -EINVAL) {
mtk_hw_set_value(dev, pin, PINCTRL_PIN_REG_R0, r0);
mtk_hw_set_value(dev, pin, PINCTRL_PIN_REG_R1, r1);
}
After:
/* try pupd_r1_r0 if pullen_pullsel return error */
err = mtk_pinconf_bias_set_pullen_pullsel(dev, pin, disable, pullup,
val);
if (err)
return mtk_pinconf_bias_set_pupd_r1_r0(dev, pin, disable,
pullup, val);
Tracing mtk_pinconf_bias_set_pullen_pullsel shows that the function
always either returns 0 in case of success or -EINVAL in case any error
has occurred. Hence the logic responsible of the decision to program R0
and R1 has been inverted.
This leads to problems on BananaPi R2 (MT7623N) when booting from
SDMMC, it turns out accessing eMMC no longer works since
U-Boot 2022.07:
MT7623> mmc dev 0
Card did not respond to voltage select! : -110
The problem wasn't detected for a long time as both eMMC and SDMMC work
fine if they are used to boot from, and hence R0 and R1 were already
setup by the bootrom and/or preloader.
Fix the logic to restore the originally intended and correct behavior
and also change the descriptive comment accordingly.

- Fix various small problems on mpc83xx platform
- Add a GPIO Driver for QE GPIOs
- Add support for mpc832x into mpc83xx SPI driver
- Refactor existing board code that will be shared with new board
- Add the new board

At present the code does ide_init() as a separate operation, then calls
device_probe() to copy over the information. We can call ide_init() from
probe just as easily.
The only difference is that using 'ide init' twice will do nothing.
However it already fails to copy over the new data in that case, so the
effect is the same. For now, unbind the block devices and remove the IDE
device, which causes the bus to be probed again. Later patches will fix
this up fully, so that all blk_desc data is copied across.
Since ide_reset() is only called from ide_init(), there is no need to init
the ide_dev_desc[] array. This is already done at the end of ide_init() so
drop this code.
The call to uclass_first_device() is now within the probe() function of
the same device, so does nothing. Drop it.

If one leaves the CQSPI_REG_CMDCTRL in an unclean state this may cause
issues in future command reads. This issue came to light when some flash
reads in STIG mode were coming back dirty.

OSPI controller supports all types of op variants in STIG mode,
only limitation being that the data payload should be less than
8 bytes when not using memory banks.
STIG mode is more stable for operations that send small data
payload and is more efficient than using DMA for few bytes of
memory accesses. It overcomes the limitation of minimum 4 bytes
read from flash into RAM seen in DAC mode.
Use STIG mode for all read and write operations that require
data input/output of less than 8 bytes from the flash, and thereby
support all four phases, cmd/address/dummy/data, through OSPI STIG.
Also, remove the reorder address chunk in apb_command_write since we now
setup ADDR BIT field that does the same job in a cleaner way.

buswidth and dtr fields in spi_mem_op are only valid when the
corresponding spi_mem_op phase has a non-zero length. For example,
SPI NAND core doesn't set buswidth when using SPI_MEM_OP_NO_ADDR
phase.
Fix the dtr checks in set_protocol() to ignore empty spi_mem_op
phases, as checking for dtr field in empty phase will result in
false negatives.

This patch adds fixups for s25fs512s to address the following issues
from reading SFDP:
- Non-uniform sectors by factory default. The setting needs to be
checked and assign erase hook as needed.
- Page size is wrongly advertised in SFDP.
- READ_1_1_2 (3Bh/3Ch), READ_1_1_4 (6Bh/6Ch), and PP_1_1_4 (32h/34h)
are not supported.
- Bank Address Register (BAR) is not supported.
In addition, volatile version of Quad Enable is used for safety.
Based on patch by Takahiro Kuwano with s25fs_s_post_bfpt_fixup() updated
to use 4-byte address commands instead of extended address mode and the
page_size is fixed to 256
For future use, manufacturer code should be moved out from framework
code as same as in Linux.
