It feels another key point is being missed though. The regmap pointer and the enable_reg/enable_mask is embedded in clk_hw to allow the same code to be used by different types of surrounding structs. Each struct: clk_pll, clk_rcg, and clk_branch in this series use the regmap interface to enable/disable the clock and they can easily do so by passing something that's always available from struct clk_hw (be it via a wrapper struct, private data member, or addition of new fields to clk_hw). If the regmap members move into each specific type of clock we can't just pass a single pointer to the enable/disable regmap functions anymore. This is the reason why I suggested a driver data pointer or container struct so that everything regmap related is contained within one type.
