Subject: clk: qcom: gcc-sa8775p: Update the GDSC wait_val fields and flags
X-Git-Tag: v6.11-rc1~109^2^2~2^2~7
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=be208c0ccf7d861fc6109ca06c1a773512739af9;p=thirdparty%2Fkernel%2Flinux.git

clk: qcom: gcc-sa8775p: Update the GDSC wait_val fields and flags

Update the GDSC wait_val fields as per the default hardware values as
otherwise they would lead to GDSC FSM state to be stuck and causing
failures to power on/off. Also add the GDSC flags as applicable and
add support to control PCIE GDSC's using collapse vote registers.
