Should GIC_SPI 306 also be here for TMU 2 channel 3?
And likewise for the r8a77980 (V3H)

The documentation seems inconsistent as I see this listed in the
interrupt controller documentation. But I do not see that channel
documented in the TMU documentation.

Should GIC_SPI 369 for TMU 4 channel 3 be present not here for
the r8a77970 (V3M) but rather below for the r8a77980 (V3H) ?

As per my note above, the documentation seems inconsistent here.
