From 171f1bc77c2d34308392841bcffa69b8a22c2e09 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 5 Dec 2011 22:28:18 -0800 Subject: [PATCH] sh: clkfwk: clock-sh7724: all div6_clks use SH_CLK_DIV6_EXT() Current div6 clocks can specify their current parent clocks from its register value if it is registered by sh_clk_div6_reparent_register(). This patch modifies all div6 clocks into SH_CLK_DIV6_EXT().
