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
