That is the MTU3, which seems to be a further evolution of the MTU2
in e.g. RZ/A1, which is already supported as a timer through the
sh_mtu2 driver?

Do you really need an MFD? (MFDs trigger a red flag for me ;-)
E.g. there are two sets of bindings for renesas,tpu: when #pwm-cells
is present, it is used for PWM, otherwise it is used as a timer.
