[PATCH 0/4] ARM: dts: exynos4210-origen: Device tree fixes

[Tomasz Figa]

This patch series fixes device tree support for Origen board:
 - memory is defined using sections of maximum allowed size
 - any pin configuration is modified to use pinctrl
 - invalid properties in sdhci nodes are replaced according to current
   mmc bindings
 - a fixed vmmc voltage regulator is added

Tested on Origen board.

Depends on:
[PATCH v2 0/2] mmc: host: sdhci-s3c: Add support for pinctrl interface

  ARM: dts: exynos4210-origen: Split memory sections
  ARM: dts: exynos4210-origen: Update for pinctrl-samsung driver

[PATCH 2/4] ARM: dts: exynos4210-origen: Update for pinctrl-samsung driver

[Tomasz Figa]

This patch updates all parts of Origen dts related to pin configuration
to use new GPIO and pinctrl bindings, instead of (now unsupported on
Exynos4) legacy gpio-samsung bindings.

Looks OK to me, I want to test 1st patch on origen board with current my
u-boot though.

Will apply, thanks.
