[PATCH v1] dt-bindings: cache: ax45mp: add 2048 as a supported cache-sets value

From: Conor Dooley
Date: Wed Aug 27 2025 - 14:04:53 EST


From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>

The QiLai implementation of this cache controller uses a cache-sets of
2048, and mandates it in an if/else block - but the definition of the
property only permits 1024. Add 2048 as an option, and deny its use
outside of the QiLai.

Fixes: 51b081cdb9237 ("dt-bindings: cache: add QiLai compatible to ax45mp")
