From 7cabf9251a2f38db1ad1e49be2738955ab61d381 Mon Sep 17 00:00:00 2001 From: David Lechner Date: Sun, 1 Sep 2019 17:58:22 -0500 Subject: bus/ti-pwmss: move TI PWMSS driver from PWM to bus subsystem The TI PWMSS driver is a simple bus driver for providing power power management for the PWM peripherals on TI AM33xx SoCs, namely eCAP, eHRPWM and eQEP. The eQEP is a counter rather than a PWM, so it does not make sense to have the bus driver in the PWM subsystem since the PWMSS is not exclusive to PWM devices.
