2a5bbb13cc pci: layerscape: add a way of specifying additional iommu mappings
In the current implementation, u-boot creates iommu mappings only
for PCI devices enumarated at boot time thus does not take into
account more dynamic scenarios such as SR-IOV or PCI hot-plug.
Add an u-boot env var and a device tree property (to be used for
example in more static scenarios such as hardwired PCI endpoints
that get initialized later in the system setup) that would allow
two things:
 - for a SRIOV capable PCI EP identified by its B.D.F specify
   the maximum number of VFs that will ever be created for it
 - for hot-plug case, specify the B.D.F with which the device
   will show up on the PCI bus
More details can be found in the included documentation:

4f0278dac5 net: sun8i-emac: Lower MDIO frequency
When sending a command via the MDIO bus, the Designware MAC expects some
bits in the CMD register to describe the clock divider value between
the main clock and the MDIO clock.
So far we were omitting these bits, resulting in setting "00", which
means "/ 16", so ending up with an MDIO frequency of either 18.75 or
12.5 MHz.
All the internal PHYs in the H3/H5/H6 SoCs as well as the Gbit Realtek
PHYs seem to be fine with that - although it looks like to be severly
overclocked (the MDIO spec limits the frequency to 2.5 MHz).
However the external 100Mbit PHY on the Pine64 (non-plus) board is
not happy with that, Ethernet was actually never working there, as the
PHY didn't probe.

As we set the EMAC clock (via AHB2) to 300 MHz in ATF (on the 64-bit
SoCs), and use 200 MHz on the H3, we need the highest divider of 128
to let the MDIO clock end up below the required 2.5 MHz.

This enables Ethernet on the Pine64(non-plus).

88ae8fba84 net: sun8i-emac: Make internal PHY handling more robust
The current implementation of sun8i_get_ephy_nodes() makes quite some
assumptions, in general relying on DT path names is a bad idea.
I think the idea of the code was to determine if we are using the
internal PHY, for which there are simpler and more robust methods:

Rewrite (and rename) the existing function to simply lookup the DT node
that "phy-handle" points to, using the device's DT node.
Then check whether the parent of that PHY node is using an "H3 internal
MDIO" compatible string. If we ever get another internal MDIO bus
implementation, we will probably need code adjustments anyway, so this
is good enough for now.

7edcb4e288 net: sun8i_emac: Simplify and fix error handling for RX
The error handling in recv() is somewhat broken, for instance
good_packet isn't really used, and it's hardly readable. Also we try
to check for short or too big packets, but those are actually filtered
out by the hardware.

Simplify the whole routine and improve the error handling:
- Bail out early if the current RX descriptor is not ready.
- Enable propagation of runt, huge and broken packets.
- Check for runt and huge packets, and return 0 to indicate this.
  This will force the framework to call free_pkt for cleanup.
- Avoid aligning the packet buffer for invalidation again.

c35380c756 net: sun8i_emac: Don't hand out TX descriptor too early
When initialising the TX DMA descriptors, we mostly chain them up,
but of course don't know about any data or its length yet.
That means they are still invalid, and the OWN bit should NOT be set
yet.

In fact when we later tell the MAC about the beginning of the chain,
and enable TX DMA in the start() routine, the MAC will start fetching
TX descriptors prematurely, as it can be seen by dumping the TX_DMA_STA
and TX_DMA_CUR_DESC registers.

Clear the owner bit, to not give the MAC the wrong illusion that it
owns the descriptors already.

mmc_of_parse() can populate the 'f_max' and 'host_caps' fields of
struct mmc_config from devicetree.
The same logic is duplicated in stm32_sdmmc2_probe(). Use
mmc_of_parse(), which is more generic.

f80b8ac69b mmc: mmc_of_parse: Enable 52 MHz support with "cap-mmc-highspeed"
"cap-mmc-highspeed" enables support for 26 MHz MMC, but there is no
additional flag to enable 52 MHz MMC. In Linux. "cap-mmc-highspeed"
is used for MMC HS at both 26MHz and 52MHz.

Use the same approach and enable MMC_CAP(MMC_HS_52) host capability
when "cap-mmc-highspeed" is found in the devicetree. In the event an
MMC card doesn't support 52 MHz, it will be clocked at a speed based
on its EXT CSD, even on 52 MHz host controllers

Second set of u-boot-atmel features for 2021.01 cycle:

This feature set brings the rework of the clock tree for sam9x60 SoC.
This makes the clock tree fully compatible with Common Clock Framework
and allows full clock configuration in U-Boot. This means that the
sam9x60 boards can boot now using U-Boot.
This also includes the definitions for sam9x60 SiPs and a divisor fix
for the clock on sama7g5 SoC.

To solve this and allow specific implementations to define them as needed
add a new get_timing callback to phy_ops and call this from the dphy_timing
function to retrieve the necessary values for the specific mode.

c90778ad70 net: e1000: add defaults for i210 TX/RX PBSIZE
Set the defaults on probe for the packet buffer size registers
for the i210.

The TX/RX PBSIZE register of the i210 resets to its default value
only at power-on - see Intel Ethernet Controller I210 Datasheet rev 3.5
chapter 8.3 'Internal Packet Buffer Size Registers'.

If something (another driver, another OS, etc.) modifies this register
from its default value, the e1000 driver doesn't function correctly. It
detects a hang of the transmitter and continuously resets the adapter.
Here we set this value to its default when resetting the i210 to
resolve this issue.

2df286390a spi: mvebu_a3700_spi: add support for cs-gpios
The device tree has a way to specify GPIO lines as chip selects.  From
the binding docs:

    So if for example the controller has 2 CS lines, and the cs-gpios
    property looks like this:

    cs-gpios = <&gpio1 0 0> <0> <&gpio1 1 0> <&gpio1 2 0>;

    Then it should be configured so that num_chipselect = 4 with the
    following mapping:

    cs0 : &gpio1 0 0
    cs1 : native
    cs2 : &gpio1 1 0
    cs3 : &gpio1 2 0

Add support for this, while retaining backward-compatibility with
existing device trees; the driver will preserve existing behavior if a
cs-gpios list is not given, or if a particular line is specified as <0>
(native).

This implementation is inspired by similar implementations in
neighboring drivers for other platforms: atmega, mxc, etc.

78804de483 mmc: fsl_esdhc: fix eMMC HS400 stability issue
There was a fix-up for eMMC HS400 stability issue in Linux.

Patch link:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/
commit/?id=58d0bf843b49fa99588ac9f85178bd8dfd651b53

Description:
Currently only LX2160A eSDHC supports eMMC HS400. According to
a large number of tests, eMMC HS400 failed to work at 150MHz,
and for a few boards failed to work at 175MHz. But eMMC HS400
worked fine on 200MHz. We hadn't found the root cause but
setting eSDHC_DLLCFG0[DLL_FREQ_SEL] = 0 using slow delay chain
seemed to resovle this issue. Let's use this as fixup for now.

Introduce the fix-up in u-boot since the issue could be reproduced
in u-boot too.

7f0f1806e3 test: pinmux: Add test for pin muxing
This extends the pinctrl-sandbox driver to support pin muxing, and adds a
test for that behaviour. The test is done in C and not python (like the
existing tests for the pinctrl uclass) because it needs to call
pinctrl_select_state.  Another option could be to add a command that
invokes pinctrl_select_state and then test everything in
test/py/tests/test_pinmux.py.

The pinctrl-sandbox driver now mimics the way that many pinmux devices
work.  There are two groups of pins which are muxed together, as well as
four pins which are muxed individually. I have tried to test all normal
paths. However, very few error cases are explicitly checked for.

9c08fbfc95 pinctrl: Add pinmux property support to pinctrl-generic
The pinmux property allows for smaller and more compact device trees,
especially when there are many pins which need to be assigned individually.
Instead of specifying an array of strings to be parsed as pins and a
function property, the pinmux property contains an array of integers
representing pinmux groups. A pinmux group consists of the pin identifier
and mux settings represented as a single integer or an array of integers.
Each individual pin controller driver specifies the exact format of a
pinmux group. As specified in the Linux documentation, a pinmux group may
be multiple integers long. However, no existing drivers use multi-integer
pinmux groups, so I have chosen to omit this feature. This makes the
implementation easier, since there is no need to allocate a buffer to do
endian conversions.

Support for the pinmux property is done differently than in Linux.  As far
as I can tell, inversion of control is used when implementing support for
the pins and groups properties to avoid allocating. This results in some
duplication of effort; every property in a config node is parsed once for
each pin in that node. This is not such an overhead with pins and groups
properties, since having multiple pins in one config node does not occur
especially often. However, the semantics of the pinmux property make such a
configuration much more appealing. A future patch could parse all config
properties at once and store them in an array. This would make it easier to
create drivers which do not function solely as callbacks from
pinctrl-generic.

This commit increases the size of the sandbox build by approximately 48
bytes.  However, it also decreases the size of the K210 device tree by 2
KiB from the previous version of this series.

The documentation has been updated from the last Linux commit before it was
split off into yaml files.

492b9917c6 cfi_flash: Fix devicetree address determination
The cfi-flash driver uses an open-coded version of the generic
algorithm to decode and translate multiple frames of a "reg" property.

This starts off the wrong foot by using the address-cells and size-cells
properties of *this* very node, and not of the parent. This somewhat
happened to work back when we were using a wrong default size of 2,
but broke about a year ago with commit 0ba41ce1b7 ("libfdt: return
correct value if #size-cells property is not present").

Instead of fixing the reinvented wheel, just use the generic function
that does all of this properly.

This fixes U-Boot on QEMU (-arm64), which was crashing due to decoding
a wrong flash base address:

Octeon uses mapped addresses for virtual and physical memory. It's not

this BUG_ON() completely, as it's not really helpful.

Please also note, that BUG_ON() is not recommended any more in the Linux

2d481b2e3e pwm: Add driver for Amlogic Meson PWM controller
This adds the driver for the PWM controller found in the Amlogic SoCs.

This PWM is only a set of Gates, Dividers and Counters:
PWM output is achieved by calculating a clock that permits calculating
two periods (low and high). The counter then has to be set to switch after
N cycles for the first half period.
The hardware has no "polarity" setting. This driver reverses the period
cycles (the low length is inverted with the high length) for
PWM_POLARITY_INVERSED.

Disabling the PWM stops the output immediately (without waiting for the
current period to complete first).

But with the G12A family, the USB complex was correctly understood and

This adds a proper driver for the glue, based on the G12A one, but with
enough changes to require a different driver in U-Boot.

d63c14cc3f net: phy: mscc: sync rx/tx delay settings with Linux on vsc85xx
The Linux kernel does set the clock delays to
- 0.2 ns (their default, and lowest, hardware value) if delays should
  not be enabled
- 2.0 ns (which causes the data to be sampled at exactly half way between
  clock transitions at 1000 Mbps) if delays should be enabled
depending on the interface mode

See https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/phy/mscc/mscc_main.c#n523

So instead of using arbitrary delay values like now, mimic this behaviour.

The behaviour is the same for all of vsc8530/8531/8540/8541 so move that
to a shared function while at it.

358599efd8 firmware: add SCMI agent uclass
This change introduces SCMI agent uclass to interact with a firmware
using the SCMI protocols [1].

SCMI agent uclass currently supports a single method to request
processing of the SCMI message by an identified server. A SCMI message
is made of a byte payload associated to a protocol ID and a message ID,
all defined by the SCMI specification [1]. On return from process_msg()
method, the caller gets the service response.

SCMI agent uclass defines a post bind generic sequence for all devices.
The sequence binds all the SCMI protocols listed in the FDT for that
SCMI agent device. Currently none, but later change will introduce
protocols.

This change implements a simple sandbox device for the SCMI agent uclass.
The sandbox nicely answers SCMI_NOT_SUPPORTED to SCMI messages.
To prepare for further test support, the sandbox exposes a architecture
function for test application to read the sandbox emulated devices state.
Currently supports 2 SCMI agents, identified by an ID in the FDT device
name. The simplistic DM test does nothing yet.

SCMI agent uclass is designed for platforms that embed a SCMI server in
a firmware hosted somewhere, for example in a companion co-processor or
in the secure world of the executing processor. SCMI protocols allow an
SCMI agent to discover and access external resources as clock, reset
controllers and more. SCMI agent and server communicate following the
SCMI specification [1]. This SCMI agent implementation complies with
the DT bindings defined in the Linux kernel source tree regarding
SCMI agent description since v5.8.

Right now, regmap_read() and regmap_write() read/write a 32-bit value

need to be used.

This means that any driver ported from Linux that relies on
regmap_{read,write}() to know the size already has to be updated at each
callsite. This makes the port harder to maintain.

So, allow specifying the read/write width to make it easier to port the
drivers, since now the only change needed is when initializing the
regmap.

7f36806c9b nand: vybrid: Re-introduce vf610_nfc.dev
This member was presumably dropped when this driver was converted from
Linux. However, it is still used in log statements during initialization.
This patch adds the member back. In addition, allocation of struct
vf610_nfc has been moved to the callers of vf610_nfc_nand_init. This allows
it to be allocated by DM (if it is being used) and for dev to be
initialized.

platform_device (which has a member `dev` pointing to a struct device) to
