commit: cab1e0a36c9dd0b0671fb84197ed294513f5adc1 From: Markus Pargmann <mpa@xxxxxxxxxxxxxx> Date: Fri, 29 Mar 2013 16:20:09 +0100 Subject: ARM: clk-imx35: Bugfix iomux clock This patch enables iomuxc_gate clock. It is necessary to be able to reconfigure iomux pads. Without this clock enabled, the clk_disable_unused function will disable this clock and the iomux pads are not configurable anymore. This happens at every boot. After a reboot (watchdog system reset) the clock is not enabled again, so all iomux pad reconfigurations in boot code are without effect. The iomux pads should be always configurable, so this patch always enables it.
