[U-Boot] [PATCH v2 0/12] Enable LCD display on snow

[Simon Glass]

This series adds a driver for TPS65090 and plumbs it in to get the LCD
working correctly on snow.

The display driver is already present, but needs information about the
display to be provided in the device tree.

The backlight also needs to be enabled - it is controlled by a FET on
the TPS65090. Note that the TPS65090 is controlled by the device tree
so will only be present if the board's device tree file specifies it.
At present this is only the case for snow, but other exynos5 boards will
use it (e.g. pit).

Note: the TPS65090 driver was sent to the list around the middle of last
year but was never applied.

Changes in v2:
- Add new patch to drop smdk5250.c file
- Add new patch to rename CHARGER_EN/DISABLE
- Removed non-device-tree operation
- Use errno.h for error return codes everywhere
- Plumb into pmic charging framework
- Fix style nit
- Use correct license header
- Use new Linux device tree bindings
- Add partial battery charging support
- Update patch name to exynos5-dt instead of smdk5250
- Move code to exynos5-dt.c
- Fix comment style
- Add #ifdef around tps65090 code
- Add a device tree node for the snow EDP bridge chip
- Only set up the EDP bridge for snow
- Add a device tree compatibility string for the EDP bridge
- Check for EDP failure and print an error in that case
- Return immediately in exynos_backlight_on() if needed
- Rebase to samsung/master
