3fbb78711c cros_ec: exynos: Match up device tree with kernel version
The U-Boot device trees are slightly different in a few places. Adjust them
to remove most of the differences. Note that U-Boot does not support the
concept of interrupts as distinct from GPIOs, so this difference remains.

For sandbox, use the same keyboard file as for ARM boards and drop the
host emulation bus which seems redundant.

b798177736 dts: peach_pit: Add SLP and RST GPIO properties in parade DT node
Now that parade driver supports reading SLP and RST GPIO
from DT, specify the same in parade DT node.

6f755eb66b dm: exynos: dts: Use GPIO bank phandles for GPIOs
U-Boot now supports using GPIOs using bank phandles instead of global
numbers. Update the exynos device tree files to use this.

9332274989 cros-ec-keyboard: Synchronize DT binding from linux
The ChromeOS EC keyboard is used by various different chromebooks. Peach
pi being the third board in the u-boot tree to use it (snow and peach
pit the other two). Rather then embedding the same big DT node in the
peach-pi DT again, copy the dtsi snippit & bindings documentation from
linux and include it in all 3 boards.

This slightly changes the dt bindings in u-boot:
  * google,key-rows becomes keypad,num-rows
  * google,key-colums becomes keypad,num-colums
  * google,repeat-delay-ms and google,repeat-rate-ms are no longer used
    and replaced by hardcoded values (similar to tegra kbc)

73186c9460 dm: exynos: Convert SPI to driver model
Move the exynos SPI driver over to driver model. This removes quite a bit
of boilerplate from the driver, although it adds some for driver model.

A few device tree additions are needed to make the SPI flash available.

2fdd7d9e1a dm: exynos: dts: Convert /include/ to #include
We should be consistent about this. The kernel has moved to #include
which breaks error reporting to some extent but does allow us to include
binding files.

e4d761000a Exynos: Use 900MHz ARM frequency in SPL for peach_pit
The device seems to hang in SPL if the full speed is used when booting from
USB, perhaps because the PMIC has not been set to the maximum ARM core
voltage yet. Slow it down to a reliable speed.

8e4ab1d582 Exynos5420: Introduce support for the Peach-Pit board
While the Exynos5420 chip is used in both Smdk5420 and in the Peach-Pit
line of devices, there could be other boards using the same chip, so a
common configuration file is being added (exynos5420.h) as well
as two common device tree files (exynos54xx.dtsi & exynos5420.dtsi).

The peach board as declared in boards.cfg is a copy of smdk5420
declaration. The configuration files are similar, but define different
default device trees, console serial ports and prompts.

The device tree files for smdk5420 and peach-pit inherit from the same
common file.
