Now that we have a clk registration API that doesn't return struct clks, we need to have some way to hand out struct clks via the clk_get() APIs that doesn't involve associating struct clk pointers with a struct clk_lookup. Luckily, clkdev already operates on struct clk_hw pointers, except for the registration facing APIs where it converts struct clk pointers into struct clk_hw pointers almost immediately. Let's add clk_hw based registration APIs so that we can skip the conversion step and provide a way for clk provider drivers to operate exclusively on clk_hw structs. This way we clearly split the API between consumers and providers. Cc: Russell King <linux@arm.linux.org.uk> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
