[Freedreno] [RFC 08/24] drm/msm/dsi: push provided clocks handling into a generic code
Dmitry Baryshkov
dmitry.baryshkov at linaro.org
Mon Mar 1 23:24:51 UTC 2021
All MSM DSI PHYs provide two clocks: byte and pixel ones.
Register/unregister provided clocks from the generic place, removing
boilerplate code from all MSM DSI PHY drivers.
