Subject: [PATCH v2 04/11] clk: qcom: ipq9574: drop the CLK_SET_RATE_PARENT
 flag from GPLL clocks

GPLL 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 GPLL clocks.

Fixes: d75b82cff488 ("clk: qcom: Add Global Clock Controller driver for IPQ9574")
Signed-off-by: Kathiravan Thirumoorthy <quic_kathirav@...cinc.com>
