Subject: [PATCH v3 0/3] drm/panel: ilitek-ili9881c: Add Tianxianwei TWX700100S0

Hello,

This series adds support for the Tianxianwei TWX700100S0 panel. The
first patch adds the Tianxianwei vendor to the vendor prefixes yaml
file.  The second patch documents the DT binding. The third patch makes
fairly standard changes to the ili9881c driver.

Runtime testing and validation was done using a patched rpi-6.12.36-v8
kernel on a CM4 using a custom carrier board designed by Scandent.

I have confirmed in writing with Tianxianwei that this patch series may
be released under the GPL after sending them an early draft for review.
This should be superfluous given my signed-off, but I want to make it
clear that I did not assume fair use when providing signed-off.

Changes in v3:
  - Fixed squash artifact in the third patch's commit message.
  - Changed v1 link to use lkml.org to address mailing list rejection
    due to "HTML part".
  - Link to v2: https://lkml.org/lkml/2025/7/14/1504
Changes in v2:
  - Fixed typos in romanizations of Chinese names:
      Tianxinwei -> Tianxianwei
      Shenzen -> Shenzhen
  - Link to v1: https://lkml.org/lkml/2025/7/14/1389
