[PATCH v3 00/12] drm/bridge: tc358768: Fixes and timings improvements

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This series contains various fixes and cleanups for TC358768. The target
of this work is to get TC358768 working on Toradex's AM62 based board,
which has the following display pipeline:

AM62 DPI -> TC358768 -> LT8912B -> HDMI connector

The main thing the series does is to improve the DSI HSW, HFP and VSDly
calculations.

Changes in v3:
- Add Peter's reviewed-bys
- Move "Default to positive h/v syncs" earlier in the series to avoid
  regression in the middle of the series
- Link to v2: https://lore.kernel.org/r/20230816-tc358768-v2-0-242b9d5f703a@xxxxxxxxxxxxxxxx

Changes in v2:
- Add "drm/tegra: rgb: Parameterize V- and H-sync polarities" so that
  Tegra can configure the polarities correctly.
- Add "drm/bridge: tc358768: Default to positive h/v syncs" as we don't
  (necessarily) have the polarities set in the mode.
- Drop "drm/bridge: tc358768: Add DRM_BRIDGE_ATTACH_NO_CONNECTOR
  support" as it's not needed for DRM_BRIDGE_ATTACH_NO_CONNECTOR
  support.
- Link to v1: https://lore.kernel.org/r/20230804-tc358768-v1-0-1afd44b7826b@xxxxxxxxxxxxxxxx
