[PATCH v9 0/3] arm64: dts: imx8mp-skov: add new 7" variant

[Steffen Trumtrar]

Add a new board variant for the Skov i.MX8MP based family of boards.

This variant uses a different 7" panel than the existing ones.
As the already upstream boards and this new one are almost identical,
convert the other device trees to a base devicetree and apply the touch
controllers and panels via overlays.

[PATCH v9 1/3] arm64: dts: freescale: imx8mp: skov: fix sort order

[Steffen Trumtrar]

The imx8mp-skov-revc-jutouch should be alphabetically before the
imx8mp-skov-revc-tian variant.

Sort the entries in the correct order.

Odd diff hunk. Next has offset difference of 300 (!!!), thus this
suggests you develop on some old tree.

[PATCH v9 2/3] arm64: dts: imx8mp-skov-revc: convert to overlays

[Steffen Trumtrar]

The i.MX8MP Skov RevC jutouch 10" and Tian 7" variants are pretty
similar, apart from the Display and touch controller.

Move the common bindings to imx8mp-skov-revc-touch.dts and convert both
variants to use overlays applied on this base version.

Add a compatible for revC-based Skov boards with a touch panel for the
common dts.

Binding change need seperate patch. This is v9.
Does rebase cause problem?

I guess "squash these two" under second binding patch was confusing.
Squash these two bindings patches.

This style generates checkpatch warning, which of course could be a
false positive but git history would tell you we never do that.

[PATCH v9 3/3] arm64: dts: imx8mp-skov: support new 7inch panel board

[Steffen Trumtrar]

This board is similar to the already upstream
imx8mp-skov-revc-jutouch-jt101tm023 but uses a different 7" panel.

That is not what krzk meant. Squash patches 2 and 4. Binding and .dts 
patches are always separate.
