Thanks for your patch!

I would drop this change (see below).

Adding renesas,tmu-sh7750 to this list is OK.

The new interrupt logic is not really correct: several TMU instances
on other SoCs do support the fourth interrupt. It just was not
documented before, or supported by the driver.
I have sent a patch to document the fourth interrupt[1]. Once that
patch has been applied, adding support for sh7751 involves adding just
two new lines.
