[U-Boot] [PATCH v2 0/6] tegra: Move tegra20 towards the 'new' display bindings

[Simon Glass]

The original tegra20 display driver was written before Linux had device tree
bindings for display. Since then Linux has developed a robust set of bindings
covering various aspects of enabling a display.

This series moves closer to those bindings by using the panel and backlight
as separate drivers. The device tree files for seaboard, ventana and harmony
thereby become almost the same as Linux.

Unfortunately this breaks the other boards, which will need a similar sync.
So I'm not sure how easy it will be to accept this series. Still, it seems
worth sending it out in the hope that board maintainers can help. I have
kept this series separate so that it can progress separately.

Changes in v2:
- Add new patch to add a copyright header and header guard to errno.h
- Add new patch to allow errno_str() to be used without CONFIG_ERRNO_STR
- Rebase to master
- Update harmony and ventana also
- Don't enable CONFIG_ERRNO_STR for each board

Simon Glass (6):
  errno: Add copyright header and header guard
  errno: Allow errno_str() to be used without CONFIG_ERRNO_STR
  tegra: dts: Sync tegra20 device tree files with Linux
  video: tegra: Move to using simple-panel and pwm-backlight
  tegra: video: Always use write-through cache on LCD
  fdt: Drop some unused compatible strings
