The RZ/G2L multi-function timer pulse unit 3 (MTU3a) is embedded in the Renesas RZ/G2L family SoC's. It consists of eight 16-bit timer channels and one 32-bit timer channel. It supports the following functions - Counter - Timer - PWM This patch series aim to add MFD and pwm driver for MTU3a. The 8/16/32 bit registers are mixed in each channel. The HW specifications of the IP is described in patch#1. Current patch set is tested for PWM mode1 on MTU3 channel. RFC->v1: * replaced devm_reset_control_get->devm_reset_control_get_exclusive * Dropped 'bindings' from the binding title * Updated the binding example * Added additionalProperties: false for counter bindings * Squashed all the binding patches * Modelled as a single counter device providing both 16-bit and 32-bit phase counting modes * Modelled as a single pwm device for supporting different pwm modes. * Moved counter and pwm bindings to respective subsystems.
