[PATCH v10 3/4] dt-bindings: arm: Document the btt3 i.MX28 based board

[Lukasz Majewski]

The imx287 based btt3 board is very similar to xea in terms of used SOM
module.

[PATCH v10 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

Changes for v10:
- Drop new line with panel-timing definitions
- Add new lines with 'sound' node
- Change 'codec' to 'audio-codec'
- Change order of properties for saif1 node
