[PATCH v2 0/4] s3c2440: mini2440: Add missing code parts to be fully working with latest kernel.

[Marek Belisko]

changes from v1 to v2: Replace original patch [4] with generic leds-gpio driver.

Patch add new LCD panels with which was board produced. Also add touchscreen
support. Enabling LCD backlight during early booting stage also added.

Some code parts are collected or inspired from other code (authors are in CC).

Marek Belisko (4):
  s3c2440: mini2440: Add support for new LCD panels.
  s3c2440: mini2440: Add touchscreen support for mini2440.
  s3c2440: mini2440: Select touchscreen by default.
  s3c2440: mini2440: Use leds-gpio driver for board leds handling.

[PATCH v2 4/4] s3c2440: mini2440: Use leds-gpio driver for board leds handling.

[Marek Belisko]

Intention of this patch is convert existing usage of leds-s3c24xx driver
to use generic gpio-leds driver. Leds are separated to 2 devices.
First device handle 4 available leds. Second device is used to drive
LCD backlight. Backlight can be controlled via parameter b so we need
separate device which is registered or not depending on parameter.

Sorry but I received no objections on this patches (no objections for
any patch previously send to mach-mini2440).
Ben could you please apply this serie to get full mini2440 support
mainstream or?
