[PATCH 0/6] Add DMA support for RZ/T2H and RZ/N2H

Posted by Cosmin Tanislav 9 hours ago

The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs have three
DMAC instances. Compared to the previously supported RZ/V2H, these SoCs
are missing the error interrupt line and the reset lines, and they use
a different ICU IP.

This series depends on the ICU series [1].
