Subject: [PATCH v2 0/8] dsi: rework clock parents and timing handling
Date: Sat, 10 Jul 2021 00:07:21 +0300 [thread overview]
Message-ID: <20210709210729.953114-1-dmitry.baryshkov@linaro.org> (raw)
This patch series brings back several patches targeting assigning dispcc
clock parents, that were removed from the massive dsi rework patchset
earlier.
Few notes:
- assign-clock-parents is a mandatory proprety according to the current
dsi.txt description.
- There is little point in duplicating this functionality with the ad-hoc
implementation in the dsi code.
On top of that come few minor cleanups for the DSI PHY drivers.
I'd kindly ask to bring all dts changes also through the drm tree, so
that there won't be any breakage of the functionality.
The patchset was tested on RB3 (single DSI), RB5 (single DSI, two
independent DSI, bonded DSI, two last configs require additional patches
which do not concern the DSI timings code).
Changes since v1:
- add dt-bindings change
- drop the patch removing msm_dsi_dphy_timing
The following changes since commit e88bbc91849b2bf57683119c339e52916d34433f:
