Subject: [PATCH v1 00/14] 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 1-11 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 12+13 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:

Greetings,
