From e4f1b49bda6d6aa2e13730ff7eeccbe65a6271f1 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Mon, 8 Feb 2016 14:59:49 -0800 Subject: clkdev: Add clk_hw based registration APIs 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.
