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 New warnings running 'make CHECK_DTBS=y freescale/imx8mp-phyboard-pollux-rdk.dtb' for 20240716083635.626596-1-cwecht@mailbox.org: Error: arch/arm64/boot/dts/freescale/imx8mp-phyboard-pollux-rdk.dts:149.17-153.12 syntax error FATAL ERROR: Unable to parse input tree make[3]: *** [scripts/Makefile.lib:442: arch/arm64/boot/dts/freescale/imx8mp-phyboard-pollux-rdk.dtb] Error 1 make[2]: *** [scripts/Makefile.build:485: arch/arm64/boot/dts/freescale] Error 2 make[2]: Target 'arch/arm64/boot/dts/freescale/imx8mp-phyboard-pollux-rdk.dtb' not remade because of errors. make[1]: *** [/home/rob/proj/linux-dt-testing/Makefile:1381: freescale/imx8mp-phyboard-pollux-rdk.dtb] Error 2 make: *** [Makefile:224: __sub-make] Error 2 make: Target 'freescale/imx8mp-phyboard-pollux-rdk.dtb' not remade because of errors.

Enable the HDMI output on the phyBOARD Pollux, using the HDMI encoder present in the i.MX8MP SoC. Please note that lcdif3 has not bee enabled. This is due the fact that as of now either HDMI or LVDS may be enabled. If both are enabled it won't worked. With this patch, however, HDMI can be enabled by turning ldcif3 on and ldcif2 off.
