[PATCH v9 4/4] ARM: dts: mxs: Add descriptions for imx287 based btt3-[012] devices

[Lukasz Majewski]

The btt3 device' HW revisions from 0 to 2 use imx287 SoC and are to
some extend similar to already upstreamed XEA devices, hence are
using common imx28-lwe.dtsi file.

New, imx28-btt3.dtsi has been added to embrace common DTS
properties for different HW revisions for this device.

As a result - changes introduced in imx28-btt3-[012].dts are
minimal.

Signed-off-by: Lukasz Majewski <lukma@denx.de>

---
Changes for v2:
- Rename dts file from btt3-[012] to imx28-btt3-[012] to match current
  linux kernel naming convention
- Remove 'wlf,wm8974' from compatible for codec@1a

Changes for v3:
- Keep alphabethical order for Makefile entries

Changes for v4:
- Change compatible for btt3 board (to 'lwn,imx28-btt3')

Changes for v5:
- Combine patch, which adds btt3-[012] with one adding board entry to
  fsl.yaml

Changes for v6:
- Make the patch series for adding entry in fsl.yaml and btt3

Changes for v7:
- Use "panel" property as suggested by the community
- Use panel-timing to specify the display parameters
- Update subject line with correct tags

Changes for v8:
- Use GPIO_ACTIVE_HIGH instead of '0'
- Add the comment regarding mac address specification
- Remove superfluous comment
- Change wifi-en-pin node name

Changes for v9:
- Remove not used 'pm-ignore-notify'
- Add display names for 'panel-dpi' compatible to avoid Schema warnings

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade

These bindings are the same except for compatible. Just combine into 1.

Can we flip these two properties, so that we have vendor specific
property after generic one?

Re: [PATCH v9 1/4] dt-bindings: display: Add powertip,st7272 as DT Schema description

Using "This patch" is not recommended per submitting-patches.rst:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?h=v6.12-rc4#n94

"Describe your changes in imperative mood, e.g. "make xyzzy do frotz"
instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy
to do frotz", as if you are giving orders to the codebase to change
its behaviour."

The same applies to patch 2/4.
