The series first updates DT bindings, so that CHECK_DTBS no longer reports any errors for i.MX6ULL (i.e. for an empty board). They are not specific to the UTi260B and in fact that machine has most of the IP handled by these patches marked as disabled. The last patch adds the actual thermal camera DT. The DT is based on reverse engineered information. More information about the device can be found in this presentation from Embedded Recipes 2023: * https://embedded-recipes.org/2023/wp-content/uploads/2023/10/Running-FOSS-on-a-Thermal-Camera-Sebastian-Reichel-compressed.pdf * https://www.youtube.com/watch?v=uvObsCG-Cqo I also prepared a branch with these patches (and a minimal kernel config) and published it here: https://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-misc.git/log/?h=uti260b-v5 Changes since PATCHv4: * https://lore.kernel.org/all/20240224213240.1854709-1-sre@kernel.org/ - drop merged patches - use new NXP mailing list - UTi260B board DT: change patch title - UTi260B board DT: fix node order Changes since PATCHv3: * https://lore.kernel.org/all/20240216223654.1312880-1-sre@kernel.org/ - weim binding: use " instead of ' - weim binding: use "if: not: required: - foo" instead of "if: properties: foo: false" - imx6ull-uti260b.dts: merge ecspi3_csgrp into ecspi3grp - collect Reviewed-by from Krzysztof Kozlowski Changes since PATCHv2: * https://lore.kernel.org/all/20240213010347.1075251-1-sre@kernel.org/ - drop fsl,imx-asrc YAML binding conversion (merged) - collect a bunch of Reviewed-by/Acked-by tags - weim DT binding: fix issue with requirements - xnur-gpio -> xnur-gpios change: Improve patch long description Changes since PATCHv1: * https://lore.kernel.org/all/20240210012114.489102-1-sre@kernel.org/ - uni-t,imx6ull-uti260b -> uni-t,uti260b - add Acked-by for uni-t vendor prefix - add Acked-by for HDMI audio index fix - add Acked-by for LCDIF power-domain requirement drop - anatop DT binding: Fixed indentation in example - anatop DT binding: Described IRQs - touchscreen DT binding: change tsc@ to touchscreen@ in example - touchscreen DT binding: change xnur-gpio to xnur-gpios - weim DT binding: drop acme,whatever example - weim DT binding: use flash@ instead of nor@ - weim DT binding: update weim.txt reference in arcx,anybus-controller.txt - weim DT binding: switch to memory-controller binding - fsl,imx-asrc DT binding: fix ASoC patch subject prefix - fsl,imx-asrc DT binding: add constraints - add new patch fixing xnur-gpio(s) in all i.MX6UL board DT files - add new patch fixing touchscreen nodename in i.MX6UL SoC DT file - add new patch fixing weim nodename in all i.MX SoC DT files - device DTS: use color/functions for the led - device DTS: increase SPI speed - device DTS: add comment for SD / eMMC node Unadressed feedback from PATCHv1: - anatop phandle vs parent: technically it makes sense to just use the parent, but this driver is only used by i.MX6. The current code makes use of the phandle, so we cannot drop it because of backwards compatibility. So I don't see a point in deprecating this property. - touchscreen binding: I kept measure-delay-time and pre-charge-time values in hex, since that is being used everywhere and the unit is unknown. The values are directly written into HW registers and the i.MX6UL TRM does not provide any hints about the unit. I do not have an i.MX6UL device with a touchsreen, so I cannot test either. - regulator name in DT: I did not rename the regulators to just "regulator", since the nodename must be unique.
