[PATCH v1 2/2] riscv: dts: renesas: add specific RZ/Five cache compatible
Posted by Conor Dooley 7 months, 1 week ago
From: Conor Dooley <conor.dooley@microchip.com>

When the binding was originally written, it was assumed that all
ax45mp-caches had the same properties etc. This has turned out to be
incorrect, as the QiLai SoC has a different number of cache-sets.

Add a specific compatible for the RZ/Five for property enforcement and
in case there turns out to be additional differences between these
implementations of the cache controller.
