Hi and sorry for the late reply,

quoted

+
+       /* Keep bimc gfx clock port on all the time */
+       clk_prepare_enable(gcc_bimc_gfx_clk.clkr.hw.clk);
+

Preferably just set these various bits with regmap_update_bits() during
probe. Also, please do it before regsitering the clks, not after.

To be fair, now I think that simply adding CLK_IS_CRITICAL flag to the clocks in question is the smartest thing to do. Magic writes don't tell a whole lot.

+       /* Set the HMSS_GPLL0_SRC for 300MHz to CPU subsystem */
+       clk_set_rate(hmss_gpll0_clk_src.clkr.hw.clk, 300000000);

Is this not already the case?

This is a mission-critical clock and we cannot trust the bootloader with setting it. Otherwise dragons might appear.
