Maybe it's time to make this idiom a function and call this? Something
like
static void sensiblefuncname(struct clk *parent, ...)
{
u32 mux = _get_mux(...);
reg = __raw_readl(offset) & ~mask;
reg |= mux << __ffs(mask);
__raw_writel(reg, offset);
}
What do you think?

I havn't checked, but I assume the functions _clk_esdhc1_set_rate and
_clk_esdhc2_set_rate can share some code?

Please align the IOMUX_PAD, and there is a space before the tab in the
