[PATCH V3] clk: imx8m: fix bus critical clk registration

2020-11-01 Thread peng . fan
From: Peng Fan noc/axi/ahb are bus clk, not peripheral clk. Since peripheral clk has a limitation that for peripheral clock slice, IP clock slices must be stopped to change the clock source. However if the bus clk is marked as critical clk peripheral, the assigned clock parent operation will fai
