[PATCH v2 0/3] Add Himax hx83112b touchscreen driver

[Job Noorman]

Hi all,

This series adds support for the Himax hx83112b. The hx83112b supports 10
point multitouch with hardware tracking of touch points. It is the
touchschreen used by the Fairphone 3.

Note that a datasheet was unavailable for this device, so it was built
based on the Android driver that was tagged as GPLv2. This series is a
complete rewrite, though, and the code bears no resemblence to the original
implementation.

It is expected that this driver can be made to work on other hx83xxx
devices, especially the hx83112a used in the Fairphone 4. However, since we
have been unable to verify this, this driver only declares compatibility
with the hx83112b and uses very specific file names.

Changes since v1:
- Fix sparse warnings. Reported-by: kernel test robot <lkp@xxxxxxxxx>.
- Fix dt_binding_check.

Best regards,
Job
