I presume you did stuff to make it fit with my upstream tiling, mention
that here.

Please sort these alphabetically and please squash all the phase_flag*
into msm_mux_phase_flag.

Please squash all tsif1 into msm_mux_tsif1.

Squash sdc4_cmd, sdc4_clk and sdc4{0,1,2,3} into msm_mux_sdc4.

Please squash all qdss_gpio into msm_mux_qdss (iirc qdss_cti is a
separate thing).
