Subject: [PATCH v2 1/3] ARM: dts: imx6sx-sdb: Convert from fbdev to drm bindings

It is preferred to use the panel compatible string rather than passing
the LCD timing in the device tree.

So pass the "sii,43wvf1g" compatible string, which describes the parallel
LCD.

Also pass the 'backlight' property as described in
Documentation/devicetree/bindings/display/panel/simple-panel.txt

Subject: [PATCH 2/3] ARM: dts: imx6sl-evk: Rearrange the regulators node

It is not recommended to place regulators inside "simple-bus", so move
them out.

The motivation for doing this is to make it easier to adding new
regulators.

Hi Marco,

You missed to pass the v2 notation for this patch in the Subject.

gpio = <&gpio4 0 GPIO_ACTIVE_HIGH>;

would easier to read.
