Users of internal MSM clocks derived from CXO should vote on the CXO_CLK RPM resource rather than just the XO buffer resource. Voting on CXO_CLK ensures the entire clock tree from the PMIC through to the MSM clock controller is running, whereas voting for the buffer does not guarantee the clock will not be gated off within the MPM.
