From: Jyri Sarha Date: Mon, 8 Aug 2016 10:09:15 +0000 (+0530) Subject: pwm: pwm-tipwmss: Remove all runtime PM gets/puts X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=549c50af251969ecc8de1f773921c2a861fd240b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git pwm: pwm-tipwmss: Remove all runtime PM gets/puts Remove all pm_runtime_get_sync() and pm_runtime_put_sync() call as well as the dummy pm_ops from the pwm-tipwmss driver. No registers are being modified. The runtime PM still needs to be enabled, so that the runtime PM framework can take care of enabling/disabling the PWMSS clock when submodules of PWMSS (ECAP or EHRPWM) call runtime PM APIs. With this change PWMSS clock goes to idle when none of the submodules are in use.
