Add MTU3 for RZ/T2H and RZ/N2H

[PATCH 07/11] dt-bindings: timer: renesas,rz-mtu3: move required resets to conditional

Posted by Cosmin Tanislav 5 days, 20 hours ago

The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs do not have a
reset line for the MTU3 block.

Prepare for adding support for them by moving the required reset into a
conditional matching all compatibles except the fallback one.
