From bed9d1bb4ed8c9bdaca77d31a2562c3a9dae43a7 Mon Sep 17 00:00:00 2001 From: Tarun Kanti DebBarma Date: Wed, 4 Jul 2012 05:00:48 -0600 Subject: [PATCH] ARM: OMAP2+: hwmod: add omap_hwmod_get_main_clk() API Add an API to get main clock name associated with a given @oh. This will avoid the need to construct fclk names during early initialization in order to get fclk handle using clk_get().
