Subject: clk: qcom: gcc-sc8280xp: use collapse-voting for PCIe GDSCs
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8d114b94fc39210b88b203b57aaf04836a87a4f0;p=linux.git

clk: qcom: gcc-sc8280xp: use collapse-voting for PCIe GDSCs

The PCIe GDSCs can be shared with other masters and should use the APCS
collapse-vote register when updating the power state.

This is specifically also needed to be able to disable power domains
that have been enabled by boot firmware using the vote register.
