From 245bd6f6af8a62a2e2e14976e5ef3dc2b82ec153 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 6 Nov 2014 15:51:00 +0200 Subject: PM / clock_ops: Add pm_clk_add_clk() The existing pm_clk_add() allows to pass a clock by con_id. However, when referring to a specific clock from DT, no con_id is available. Add pm_clk_add_clk(), which allows to specify the struct clk * directly. The will will increment refcount on clock pointer, so the caller has to use clk_put() on clock pointer when done.
