Anson Huang 9f4c8f9607 pwm: imx: Add ipg clock operation ... i.MX PWM module's ipg_clk_s is for PWM register access, on most of i.MX SoCs, this ipg_clk_s is from system ipg clock or perclk which is always enabled, but on i.MX7D, the ipg_clk_s is from PWM1_CLK_ROOT which is controlled by CCGR132, that means the CCGR132 MUST be enabled first before accessing PWM registers on i.MX7D. This patch adds ipg clock operation to make sure register access successfully on i.MX7D and it fixes Linux kernel boot up hang during PWM driver probe.
