Taniya Das f0cc5f7cb4 pmdomain: qcom: rpmhpd: Skip retention level for Power Domains ... commit ddab91f4b2 upstream. In the cases where the power domain connected to logics is allowed to transition from a level(L)-->power collapse(0)-->retention(1) or vice versa retention(1)-->power collapse(0)-->level(L) will cause the logic to lose the configurations. The ARC does not support retention to collapse transition on MxC rails. The targets from SM8450 onwards the PLL logics of clock controllers are connected to MxC rails and the recommended configurations are carried out during the clock controller probes. The MxC transition as mentioned above should be skipped to ensure the PLL settings are intact across clock controller power on & off. On older targets that do not split MX into MxA and MxC does not collapse the logic and it is parked always at RETENTION, thus this issue is never observed on those targets.
