6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Satya Priya Kakitapalli <quic_skakitap@xxxxxxxxxxx>
commit bab0c7a0bc586e736b7cd2aac8e6391709a70ef2 upstream.
The branch clocks of gcc_cpuss_ahb_clk_src are marked critical
and hence these clocks vote on XO blocking the suspend.
De-register these clocks and its source as there is no rate
setting happening on them.
Fixes: 4433594bbe5d ("clk: qcom: gcc: Add global clock controller driver for SC8180x")
