msm_dsi_host_set_phy_mode().

There is no reason to set clock parents manually, use device tree to
assign DSI/display clock parents to DSI PHY clocks. Dropping this manual
setup allows us to drop repeating code and to move registration of hw
clock providers to generic place.

Just a minor comment, can you also include the part which removes
msm_host->cphy_mode = src_phy->cphy_mode; from msm_dsi_host_set_src_pll
in this change itself so that its clear that you are removing from there
and moving it into a new API?

You can still keep my

once you address this.
