See imx28-evk.dts for an example.

This file has the: panel { compatible = "sii,43wvf1g"; Whereas in those devices (i.e. btt3) - I don't know the names of the displays - manufacturer buys them according to the timing properties. Hence the question - how shall I proceed? IMHO the most straightforward way is to modify fsl,lcdif.yaml to not require "port" and "remote-endpoint" and instead add support for "display-timings" and "timingX" Especially that Documentation/devicetree/bindings/display/panel/display-timings.yaml are already defined and used by many imx boards (from imx25 to imx6q) - git grep -n "display-timings" Even the imx28-m28evk.dts is using the "display-timings" and not "remote-endpoint" approach.

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 --- arch/arm/boot/dts/nxp/mxs/Makefile | 3 + arch/arm/boot/dts/nxp/mxs/imx28-btt3-0.dts | 12 + arch/arm/boot/dts/nxp/mxs/imx28-btt3-1.dts | 8 + arch/arm/boot/dts/nxp/mxs/imx28-btt3-2.dts | 12 + arch/arm/boot/dts/nxp/mxs/imx28-btt3.dtsi | 320 +++++++++++++++++++++ 5 files changed, 355 insertions(+) create mode 100644 arch/arm/boot/dts/nxp/mxs/imx28-btt3-0.dts create mode 100644 arch/arm/boot/dts/nxp/mxs/imx28-btt3-1.dts create mode 100644 arch/arm/boot/dts/nxp/mxs/imx28-btt3-2.dts create mode 100644 arch/arm/boot/dts/nxp/mxs/imx28-btt3.dtsi
