Retire SDM845-cheza devboards

[PATCH v2 0/4] Retire SDM845-cheza devboards

Posted by Konrad Dybcio 2 months, 3 weeks ago

Cheza was a prototype class of boards, based on the 2017 SDM845 SoC,
used for bringing up ChromiumOS on Snapdragon platforms.

Today, almost none are left in existence, and the small amount of
remaining ones don't get any real use.

To ease maintenance burden, remove it from the kernel tree.

Changes in v2:
- Drop the MAINTAINERS entry
  I wasn't sure whether to go with a separate commit, I'm fine with it
  being squashed if that's preferred
- Drop the dt-bindings, as the board practically doesn't exist anymore
- Drop the SMMU bindings entry
- Link to v1: https://lore.kernel.org/r/20250715-topic-goodnight_cheza-v1-1-68b67d60c272@oss.qualcomm.com
