Any attempt to enable titan_top_gdsc on SM8550-QRD fails and produces an error message that the gdsc is stuck at 'off' state, this can be easily verified just by setting cci0 status on: cam_cc_titan_top_gdsc status stuck at 'off' WARNING: CPU: 6 PID: 89 at drivers/clk/qcom/gdsc.c:178 gdsc_toggle_logic+0x154/0x168 However if MMCX power domain is replaced by MXC one, it allows to turn titan_top_gdsc on successfully, even if MMCX is remained off according to /sys/kernel/debug/pm_genpd/pm_genpd_summary report.
