Hi Dong,

Thanks for working on this series.

Tested the whole series on a mx7d-sdb and it does fix the several clk
warnings that we currently have.

I had to change this to:

--- a/drivers/clk/imx/clk-pllv3.c
+++ b/drivers/clk/imx/clk-pllv3.c
@@ -108,7 +108,7 @@ static long clk_pllv3_round_rate(struct clk_hw *hw, unsigned
 static int clk_pllv3_set_rate_done(struct clk_hw *hw)
 {
        struct clk_pllv3 *pll = to_clk_pllv3(hw);
-       u32 val = readl_relaxed(pll->base) & pll->powerdown;
+       u32 val = readl_relaxed(pll->base) & pll->power_bit;

,so that it can build against linux-next.
