The current code invalidates the range after the read buffer since the
buffer pointer gets incremented in the read loop. Use a temporary

07c652400d rtc: ds1307: Handle oscillator-stop bit correctly
The DS1307 driver was originally based on the DS1337 driver. However,
the functionality of the clock set/get functions has diverged. In the
original DS1337 driver, the set/get functions did the following:
  1) Setting the clock ensured the oscillator was enabled.
  2) Getting the clock checked and reset the oscillator-stop flag.
The DS1307 does not have an oscillator-stop flag, but the driver tried
(incorrectly) to emulate this by ensuring the oscillator was running. It
really makes no sense to start a stopped clock without setting it.

This patch makes the DS1307 driver behave like the original DS1337
driver again. For the DS1307 itself, this is just a removal of code,
since there is no oscillator-fail bit to check or reset, and the clock
is started when it is set. Since the DS1307 driver can now also be used
for the DS1337 and DS1340 which do have this bit, add code to handle the
oscillator-stop bit in the same was the original DS1337 driver did --
i.e. report that the oscillator had stopped and clear the flag.

This means that setting the date using the date command (which does both
a get and a set) will now clear the oscillator-stop flag in addition to
setting and starting the clock.

The old-style (non-DM) code has not been updated and will be removed in
a future patch. Note that this older code does not support the DS1337,
as there is a separate driver for this. Also note that the original (DM)
code used the wrong control-register address for the DS1337.

The bulk of it is Samuel's DM_I2C rework, which removes the nasty I2C
deprecation warnings for most 32-bit boards. It also includes some
smaller refactorings that pave the way for more changes, mostly driven
by needing to support the Allwinner RISC-V SoC later on.

Board wise we gain support for the FriendlyARM NanoPi R1S H5 router
board and official Pinetab support.

Build-tested for all 160 sunxi boards, and boot tested on a A64, A20,
H3, H6, and H616 board. USB, SD card, eMMC, and Ethernet all work there
(where applicable).

2421497cb7 sunxi: video: Convert panel I2C to use DM_I2C
Two displays supported by the sunxi display driver (each one used by a
single board) require initialization over I2C. Both previously used
i2c_soft; replace this with the i2c-gpio instance that already exists in
those boards' device trees (sun5i-a13-utoo-p66 and sun6i-a31-colombus).

Since the i2c-gpio nodes are not referenced by any other node in the
device trees (the device trees have no panel node), the I2C bus is
selected by its node name.

This panel initialization code was the only i2c_soft user, so the
i2c_soft GPIO setup code can be removed now as well.

3227c85fe7 i2c: Add a DM_I2C driver for the sun8i RSB controller
This bus controller is used to communicate with an X-Powers AXP PMIC.
Currently, various drivers access PMIC registers through a platform-
specific non-DM "pmic_bus" interface, which depends on the legacy I2C
framework. In order to convert those drivers to use DM_PMIC, this bus
needs a DM_I2C driver.

Refactor the rsb functions to take the base address as a parameter,
and implement both the existing interface (which is still needed in
SPL) and the DM_I2C interface on top of them.

The register for switching between I2C/P2WI/RSB mode is the same across
all PMIC variants, so move that to the common header.

There are only a couple of pairs of hardware/runtime addresses used
across all PMIC variants. So far the code expected only the "primary"
pair, but some PMICs like the AXP305 and AXP805 use the secondary pair,
so add support for that to the DM driver as well.

165e8fe5db clk: ti: add am33xx/am43xx spread spectrum clock support
The patch enables spread spectrum clocking (SSC) for MPU and LCD PLLs.
As reported by the TI spruh73x/spruhl7x RM, SSC is only supported for
the DISP/LCD and MPU PLLs on am33xx/am43xx. SSC is not supported for
DDR, PER, and CORE PLLs.

Calculating the required values and setting the registers accordingly
was taken from the set_mpu_spreadspectrum routine contained in the
arch/arm/mach-omap2/am33xx/clock_am33xx.c file of the u-boot project.

In locked condition, DPLL output clock = CLKINP *[M/N]. In case of
SSC enabled, the reference manual explains that there is a restriction
of range of M values. Since the clk_ti_am3_dpll_round_rate() attempts
to select the minimum possible N, the value of M obtained is not
guaranteed to be within the range required. With the new "ti,min-div"
parameter it is possible to increase N and consequently M to satisfy the
constraint imposed by SSC.

425084610e sunxi: Clean up inclusions of asm/arch/gpio.h
As part of migrating to DM_GPIO and DM_PINCTRL, eventually we will
remove the asm/arch/gpio.h header. In preparation, clean up the various
files that include it.

Some files did not contain any GPIO code at all, so this header was
completely unused.

A few files contained only legacy platform-specific GPIO code for
setting up pin muxes. They were left unchanged, as that code will be
completely removed by the DM_PINCTRL migration.

The remaining files contain some combination of DM_GPIO and legacy GPIO
code. For those, switch to including asm/gpio.h (if it wasn't included
already). Right now, this header provides both sets of functions,
because ARCH_SUNXI selects GPIO_EXTRA_HEADER. This will still be the
right header to include once the DM_GPIO migration is complete and
GPIO_EXTRA_HEADER is no longer needed.

The digital filter related computation are present in the driver
however the programming of the filter within the IP is missing.
The maximum value for the DNF is wrong and should be 15 instead of 16.

1fd9eb68d6 i2c: stm32f7: move driver data of each instance in a privdata
Today all the I2C instance point on the same global
variable stm32_i2c_setup according the compatible: i2c_priv->setup =
pointer to the same driver data.

This patch changes this driver data (stm32f7_setup and stm32mp15_setup)
to a const struct and move the timing struct 'setup' as element of i2c
privdata, initialized in stm32_ofdata_to_platdata() with the driver
configuration data.

This patch solves issues when several I2C instance have not the same
clock source or not the same configuration: each timing setup is saved
is the I2C privdata.

1d7ad68559 arm: a37xx: pci: Handle propagation of CRSSVE bit from PCIe Root Port
Now that PCI Bridge (PCIe Root Port) for Aardvark is emulated in U-Boot,
add support for handling and propagation of CRSSVE bit.

When CRSSVE bit is unset (default), driver has to reissue config
read/write request on CRS response.

CRSSVE bit is supported only when CRSVIS bit is provided in read-only
Root Capabilities register. So manually inject this CRSVIS bit into read
response for that register.

cb056005dc arm: a37xx: pci: Add support for accessing PCI Bridge on root bus
Aardvark does not have a real PCIe Root Port device on the root bus.
Instead it has PCIe registers of PCIe Root Port device mapped in
internal Aardvark memory space starting at offset 0xc0.

The PCIe Root Port itself is normally available as a PCI Bridge device
on the root bus with bus number zero. Aardvark instead has the
configuration registers of this PCI Bridge at offset 0x00 of Aardvark's
memory space, but the class code of this device is Mass Storage
Controller (0x010400), instead of PCI Bridge (0x600400), which causes
U-Boot to fail to recognize it as a P2P Bridge

Add a hook into the pcie_advk_read_config() / pcie_advk_write_config()
functions to redirect access for root bus from PIO transfer to this
internal Aardvark memory space. This will allow U-Boot to access
configuration space of this PCI Bridge which represents PCIe Root Port.

Redirect access to PCI Bridge registers in range 0x10 - 0x34 to driver's
internal buffer (cfgcache[]). This is because at those addresses
Aardvark has different registers, incompatible with config space of a
PCI Bridge.

Redirect access to PCI Bridge register PCI_ROM_ADDRESS1 (0x38) to
Aardvark internal address for that register (0x30).

When reading PCI Bridge register PCI_HEADER_TYPE, set it explicitly to
value Type 1 (PCI_HEADER_TYPE_BRIDGE) as PCI Bridge must be of Type 1.

When writing to PCI_PRIMARY_BUS or PCI_SECONDARY_BUS registers on this
PCI Bridge, correctly update driver's first_busno and sec_busno
variables, so that pcie_advk_addr_valid() function can check if address
of any device behind the root bus is valid and that PIO transfers are
started with correct config type (1 vs 0), which is required for
accessing devices behind some PCI bridge after the root bus.

U-Boot's PCI_PNP code sets primary and secondary bus numbers as relative
to the configured bus number of the root bus. This is done so that
U-Boot can support multiple PCIe host bridges or multiple root port
buses, when internal bus numbers are different.

Now that root bus is available, update code in pcie_advk_read_config()
and pcie_advk_write_config() functions to correctly calculate real
Aardvark bus number of the target device from U-Boot's bus number as:
  busno = PCI_BUS(bdf) - dev_seq(bus)

Stefan: Small fix of header masking as suggested by Pali.
