From 035a61c314eb3dab5bcc5683afaf4d412689858a Mon Sep 17 00:00:00 2001 From: Tomeu Vizoso Date: Fri, 23 Jan 2015 12:03:30 +0100 Subject: clk: Make clk API return per-user struct clk instances Moves clock state to struct clk_core, but takes care to change as little API as possible. struct clk_hw still has a pointer to a struct clk, which is the implementation's per-user clk instance, for backwards compatibility. The struct clk that clk_get_parent() returns isn't owned by the caller, but by the clock implementation, so the former shouldn't call clk_put() on it. Because some boards in mach-omap2 still register clocks statically, their clock registration had to be updated to take into account that the clock information is stored in struct clk_core now.
