[PATCH v2 07/11] drm/msm/dsi_phy_28nm_8960: Replace parent names with clk_hw pointers

Marijn Suijten
2022-06-01T22:08:16Z

parent_hw pointers are easier to manage and cheaper to use than
repeatedly formatting the parent name and subsequently leaving the clk
framework to perform lookups based on that name.
