fe6293a809 phy: atheros: add device tree bindings and config
Add support for configuring the CLK_25M pin as well as the RGMII I/O
voltage by the device tree.

By default the AT803x PHYs outputs the 25MHz clock of the XTAL input.
But this output can also be changed by software to other frequencies.
This commit introduces a generic way to configure this output.

Also the PHY supports different RGMII I/O voltages: 1.5V, 1.8V and 2.5V.
An internal LDO is able to provide 1.5V (default) and 1.8V. The 2.5V
option needs an external supply voltage. This commit adds support to
switch the internal LDO to 1.8V.

3fb22bc2f8 gpio/mpc83xx_spisel_boot.c: gpio driver for SPISEL_BOOT signal
Some SoCs in the mpc83xx family, e.g. mpc8309, have a dedicated spi
chip select, SPISEL_BOOT, that is used by the boot code to boot from
flash.

This chip select will typically be used to select a SPI boot
flash. The SPISEL_BOOT signal is controlled by a single bit in the
SPI_CS register.

Implement a gpio driver for the spi chip select register. This allows a
spi driver capable of using gpios as chip select, to bind a chip select
to SPISEL_BOOT.

It may be a little odd to do this as a GPIO driver, since the signal
is neither GP or I, but it is quite convenient to present it to the
spi driver that way. The alternative it to teach mpc8xxx_spi to handle
the SPISEL_BOOT signal itself (that is how it's done in the linux
kernel, see commit 69b921acae8a)

9368bdfebd ram: stm32mp1: the property st, phy-cal becomes optional
This parameter "st,phy-cal" becomes optional and when it is
absent the built-in PHY calibration is done.

It is the case in the helper dtsi file "stm32mp15-ddr.dtsi"
except if DDR_PHY_CAL_SKIP is defined.

This patch also impact the ddr interactive mode
- the registers of the param 'phy.cal' are initialized to 0 when
  "st,phy-cal" is not present in device tree (default behavior when
  DDR_PHY_CAL_SKIP is not activated)
- the info 'cal' field can be use to change the calibration behavior
  - cal=1 => use param phy.cal to initialize the PHY, built-in training
             is skipped
  - cal=0 => param phy.cal is absent, built-in training is used (default)

ba6fb2f6ac dm: i2c-gpio: add support for clock stretching
This adds support for clock stretching to the i2c-gpio driver. This is
accomplished by switching the GPIO used for the SCL line to an input
when it should be driven high, and polling on the SCL line value until
it goes high (indicating that the I2C slave is no longer pulling it
low).

This is enabled by default; for gpios which cannot be configured as
inputs, the i2c-gpio,scl-output-only property can be used to fall back
to the previous behavior.

U-Boot itself does not have interrupt-driven handlers, so just provide a

peripherals which must use an interrupt to determine when data is
available, for example.

7e589bc19b x86: Add a generic Intel GPIO driver
Add a GPIO driver which uses the pinctrl driver to access the pad
information. This driver relies on the GPIO nodes being subnodes to the
pinctrl device.

74749f1e84 x86: Add a generic Intel pinctrl driver
Recent Intel SoCs share a pinctrl mechanism with many common elements. Add
an implementation of this core functionality, allowing SoC-specific
drivers to avoid adding common code.

As well as a pinctrl driver this provides a GPIO driver based on the same
code.

Once other SoCs use this driver we may consider moving more properties to
the device tree (e.g. the community info and pad definitions).

2206ac248a dm: pci: Allow delaying auto-config until after relocation
At present PCI auto-configuration happens in U-Boot both before and after
relocation. This is a waste of time and may mess up static addresses used
in board_init_f(). Adjust the code to supporting doing auto-configuration
once, after relocation, under control of a device-tree property.

This is needed for Apollo Lake for debugging the silicon-init code. Once
the UART is moved to a different MMIO address the debug UART does not work
and any debug output in Apollo Lake's arch_fsp_init_r() causes a hang.

93ce16fd0a doc: really get rid of Documentation/ directory
Commit 656d8da9d2 (doc: Remove duplicated documentation directory) got
rid of most of Documentation/. But there's still an obviously useless
.gitignore left behind.

Also, there's a copy of the linux kernel's net/ethernet.txt binding
imported from v5.0, while the existing one in doc/ is from 4.0-rc1. So
replace the latter by the former, and making Documentation/ finally
empty.

fb6038390e dt-bindings: phy: dp83867: Add documentation for disabling clock output
Based on commit 980066e6d964 ("dt-bindings: phy: dp83867: Add documentation
for disabling clock output") of mainline linux kernel.

The clock output is generally only used for testing and development and not
used to daisy-chain PHYs.  It's just a source of RF noise afterward.

Add a mux value for "off".  I've added it as another enumeration to the
output property.  In the actual PHY, the mux and the output enable are
independently controllable.  However, it doesn't seem useful to be able
to describe the mux setting when the output is disabled.

Document that PHY's default setting will be left as is if the property
is omitted.

260777fc23 clk: cdce9xx: add support for cdce9xx clock synthesizer
Add support for CDCE913/925/937/949 family of devices. These are modular
PLL-based low cost, high performance, programmable clock synthesizers,
multipliers and dividers. They generate up to 9 output clocks from a
single input frequency. The initial version of the driver does not
support programming of the PLLs, and thus they run in the bypass mode
only. The code is loosely based on the linux kernel cdce9xx driver.
