From b5272b509a8570bb559156001e74ee162c5cb96a Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Wed, 21 Jul 2010 10:13:06 +0000 Subject: sh: add a list of parent configurations to struct clk Many system clocks can select a parent by writing a value to a specific field in the configuration register. Add a list of parents and location and width of the source selection field in the clock configuration register to struct clk to assist in clk_set_parent() implementation.
