[PATCH v2 01/11] clk: qcom: ipq8074: drop the CLK_SET_RATE_PARENT flag from PLL clocks

From: Kathiravan Thirumoorthy
Date: Thu Sep 14 2023 - 03:00:33 EST


GPLL, NSS crypto PLL clock rates are fixed and shouldn't be scaled based
on the request from dependent clocks. Doing so will result in the
unexpected behaviour. So drop the CLK_SET_RATE_PARENT flag from the PLL
clocks.

Changes in V2:
- Include the stable mailing list
- Keep the CLK_SET_RATE_PARENT in UBI32 PLL, looks like these
PLL rates can be changed. So don't drop the flag.
