Might it not be better to introduce regmap variants?
static inline void clk_regmap_writel(u32 val, u32 reg, struct regmap
*regmap)
and corresponding readl? that allows cleaner readability for clk
drivers that use regmap and those that dont.
regmap can also return error value that could also be handled as a result.
