mfd: Add Renesas RZ/G2L MTU3a core driver
The RZ/G2L multi-function timer pulse unit 3 (MTU3a) is embedded in
the Renesas RZ/G2L family SoCs. It consists of eight 16-bit timer
channels and one 32-bit timer channel. It supports the following
functions
- Counter
- Timer
- PWM
The 8/16/32 bit registers are mixed in each channel.
Add MTU3a core driver for RZ/G2L SoC. The core driver shares the
clk and channel register access for the other child devices like
Counter, PWM and Clock event.
