[U-Boot] [PATCH v5 0/15] samsung: Use common config files with Samsung boards

[Simon Glass]

This series tries to unify the Samsung board configs into a few header
files for exynos5 and exynos4.

The purpose is to make it easier to move to driver model. In that case
I would like things like the GPIO drivers and serial drivers to work in
a standard way, and not need to support device tree and platform data at
the same time. That would be quite painful.

Another reason is that the Chrome OS EC drivers are currently included in
boards that don't have a Chrome OS EC. This concern was raised by the
Samsung maintainer (Minkyu) a while back.

There are still a few boards that don't use CONFIG_OF_CONTROL so I have
updated these rudimentary of device tree files based on feedback.

This series has the side-effect of getting the EC interface working
properly on Pit, so the keyboard works. It also provides access to the
TPS65090 PMIC, which means that the backlight is enabled.

Changes in v5:
- Rebase on top of samsung/master

Changes in v4:
- Address review nits from Minkyu
- Make this driver more like the one it came from
- Rebase on top of master (CONFIG_OF settings moved to Kconfig)
- Remove special FET_ERR_NOT_READY etc. as use standard errors

Changes in v3:
- Adjust device tree file based on Robert Baldyga's example

Changes in v2:
- Add new patch to enable keyboard on pit
- Add new patch to split out cros_ec drivers
- Add new patch to use 900MHz ARM frequeny in SPL for peach_pit
- Avoid using a common file, and just add a device tree
- Don't enable the cros_ec on smdk5420
- Fix 'cashe' typo in commit subject
- Fix device tree base addresses
- Leave CONFIG_SERIAL3 in the individual board files
- Leave in a few configs which are not in fact common to all boards
- Reduce the number of common elements to avoid needing #undefs later
- Slightly reword the commit message
