[Freedreno] [PATCH v4 23/24] drm/msm/dsi: inline msm_dsi_phy_set_src_pll
Dmitry Baryshkov

Wed Mar 31 10:57:34 UTC 2021
The src_truthtable config is not used for some of phys, which use other
means of configuring the master/slave usecases. Inline this function
with the goal of removing src_pll_id argument in the next commit.
