    Subject[PATCH v3 00/16] UNI-T UTi260B support
    Date
    From: Sebastian Reichel <sebastian.reichel@collabora.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:

    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-v3

    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,
