Subject: [PATCH RFC 0/8] Add RZ/G2L MTU3a MFD and Counter driver
Date: Mon, 26 Sep 2022 14:21:06 +0100	[thread overview]
Message-ID: <20220926132114.60396-1-biju.das.jz@bp.renesas.com> (raw)

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 counter driver for MTU3a.
Subsequent patch seies will add TImer and PWM driver support
also enhancements to counter driver.

The 8/16/32 bit registers are mixed in each channel. The HW
specifications of the IP is described in patch#2.

Current patch set is tested for 16-bit phase counting mode on
MTU1 channel.

Please share your valuable comments on this patch series.
