To achieve the same, we need to park the APPS PLL source to GPLL0, re configure the PLL and then switch the source to APSS_PLL_EARLY. To support this, register a clock notifier to get the PRE_RATE and POST_RATE notification. Change the APSS PLL source to GPLL0 when PRE_RATE notification is received, then configure the PLL and then change back the source to APSS_PLL_EARLY. Additionally, not all SKUs of IPQ53xx support scaling. Hence, do the above to the SKUs that support scaling.
