Subject: [PATCH v4 00/16] UNI-T UTi260B support
From: Sebastian Reichel <sebastian.reichel@...labora.com>
Hi,
This adds adds support for the UNI-T UTi260B thermal camera, which is based
on i.MX6ULL. Patches 1-14 clean up all warnings reported by CHECK_DTBS 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. Then patches 15+16 introduce the vendor and board compatible DT
bindings. Finally the last patches adds support for the thermal camera itself.
The DT is based on reverse engineered information. More information about
the device can be found in this presentation from Embedded Recipes 2023:

* 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-v4
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.
Greetings,
-- Sebastian
