[PATCH 0/3] Add RZ/G2L MTU3a MFD and pwm driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
