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: d9db07f088af ("clk: qcom: Add ipq6018 Global Clock Controller support") 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.
