You want to backport this to 6.9, but you also want to backport
the driver patch to 6.10, "meh"
I'm not sure it makes sense to backport functionally, as this would
only exhibit issues if:
a) the UEFI did no work to enable the refclk
or:
b) unused cleanup would happen
but the board would not survive booting with b) in v6.9, at least
it wouldn't have display - see Commit b60521eff227 ("clk: qcom:
gcc-x1e80100: Unregister GCC_GPU_CFG_AHB_CLK/GCC_DISP_XO_CLK")
and a) is not something we'd hit on any of the upstream-supported
targets
