[RFC 13/24] drm/msm/dsi: replace PHY's init callback with configurable data
Dmitry Baryshkov
dmitry.baryshkov at linaro.org
Mon Mar 1 23:24:56 UTC 2021
DSI PHY init callback would either map dsi_phy_regulator or dsi_phy_lane
depending on the PHY type. Replace those callbacks with configuration
options governing mapping those regions.
