[PATCH 1/6] dt-bindings: timer: renesas,rz-mtu3: Improve documentation

[Biju Das]

Fix the documentation issues pointed by Pavel while backporting
it to 6.1.y-cip.
 - Replace '32- bit'->'32-bit'
 - Consistently remove '.' at the end of line for the specifications
 - Replace '          (excluding MTU8)'-> '(excluding MTU8)'

[PATCH 2/6] dt-bindings: timer: renesas,rz-mtu3: Fix overflow/underflow interrupt names

[Biju Das]

As per R01UH0914EJ0130 Rev.1.30 HW manual the MTU3 overflow/underflow
interrupt names starts with 'tci' instead of 'tgi'.

Fix this documentation issue by replacing below overflow/underflow
interrupt names:
 - tgiv0->tciv0
 - tgiv1->tciv1
 - tgiu1->tciu1
 - tgiv2->tciv2
 - tgiu2->tciu2
 - tgiv3->tciv3
 - tgiv4->tciv4
 - tgiv6->tciv6
 - tgiv7->tciv7
 - tgiv8->tciv8
 - tgiu8->tciu8

I assume this means that nothing is actually using these interrupt
names?

Yes, That is correct. Corresponding driver doesn't have interrupt support.

[PATCH 3/6] dt-bindings: timer: renesas,rz-mtu3: Document RZ/G2UL SoC

[Biju Das]

Add MTU3a binding documentation for Renesas RZ/G2UL SoC.

MTU3a block is identical to one found on RZ/G2L, so no driver changes are
required. The fallback compatible string "renesas,rz-mtu3" will be used
on RZ/G2UL.
