that would be ideal, but I also need to deal with the common clock framework,
which doesn't support regmap: clk_register_divider(), clk_register_mux(),
clk_register_gate(), all take a void __iomem * to access clock control
registers, so as far as I can understand we can't use regmap, unless of
course we convert the common clock framework to regmap.

Thanks
