Subject: [PATCH v4 00/13] drm/bridge: tc358762: Various small fixes
Date: Mon, 07 Sep 2026 14:27:55 +0300 [thread overview]
Message-ID: <20260907-tc358762-fixes-v4-0-e3fc3ab5cd83@ideasonboard.com> (raw)
While trying to get Raspberry Pi display v1.1 working on Beagleboard
platforms, I noticed various small issues with the tc358762 driver.
The series also contains a patch to fix the timings in the
powertip,ph800480t013-idf02 panel. The combination of tc358762 +
ph800480t013 is used in the Raspberry Pi display module, so it makes
sense to fix them together.

Changes in v4:
- Rebased on latest upstream, fixing the minor compilation issues that it
brought
- Added R-b tags
- Link to v3: https://lore.kernel.org/r/20260513-tc358762-fixes-v3-0-6698b55008b9@ideasonboard.com
Changes in v3:
- Add missing #include <linux/bitfield.h>
- New patch: "drm/panel-simple: Fix powertip,ph800480t013-idf02 timings"
- Link to v2: https://lore.kernel.org/r/20260327-tc358762-fixes-v2-0-3589d3c45f4a@ideasonboard.com
Changes in v2:
- Always enable VTG. There should be no downside, and it fixes unstable
hsync
- Add four new patches at the end
- Extend the patch desc in "Drop SPICMR write" a bit
- Link to v1: https://lore.kernel.org/r/20260326-tc358762-fixes-v1-0-65f479227af5@ideasonboard.com
