RE: [PATCH 2/2] clk: imx: disable i.mx7ulp composite clock during initialization

Hi, Stephen I think we should resume this thread, without this patch, mainline kernel boot up will cause mmc timeout all the time. If it is NOT good to disabling those peripheral devices' clock in i.MX7ULP's clock driver, then we have to change the core framework to disable clock explici

[PATCH 2/2] clk: imx: disable i.mx7ulp composite clock during initialization

i.MX7ULP peripheral clock ONLY allow parent/rate to be changed with clock gated, however, during clock tree initialization, the peripheral clock could be enabled by bootloader, but the prepare count in clock tree is still zero, so clock core driver will allow parent/rate changed even with CLK_SET_R
