Subject: [PATCH] clk: qcom: ipq8074: drop the CLK_SET_RATE_PARENT flag from
 PLL clocks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.
