[PATCH v10 0/4] 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.

[Steffen Trumtrar]

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

Sort the entries in the correct order.

[PATCH v10 2/4] dt-bindings: arm: fsl: add compatibles for Skov i.MX8MP boards

[Steffen Trumtrar]

Add a compatible for all revC-based Skov boards with a touch panel.

Also, in preparation for adding a new device tree variant with a
different 7" panel than the already mainline ones, also describe that DT
compatible in the binding.

[PATCH v10 3/4] 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.

[Steffen Trumtrar]

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

I do not understand this. This is a board, so not an overlay.

So what skov,imx8mp-skov-revc-touch is? I asked some revisions ago not
to add generic compatibles.

yes, that's what I did up until v4. New board with new dts.

- Link to v4: https://patch.msgid.link/20260706-v7-0-topic-imx8mp-skov-dts-jutouch-7inch-v4-0-dfc0c8827c02@pengutronix.de

The boards are all very similar apart from the touch panel, but they are all "real" boards and don't share a SOM, so dtsi is also not correct.

Steffen
