Doing so will result in the unexpected behaviour. So drop the CLK_SET_RATE_PARENT flag from the PLL clocks. Cc: stable@vger.kernel.org Fixes: b8e7e519625f ("clk: qcom: ipq8074: add remaining PLL’s") Signed-off-by: Kathiravan Thirumoorthy --- 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.
