From 009b21f392759ca7be91bc4be9d9534f6cee2878 Mon Sep 17 00:00:00 2001 From: Tinghan Shen Date: Wed, 22 Jun 2022 14:22:42 +0800 Subject: [PATCH 1/4] dt-bindings: dsp: mediatek: Use meaningful names for mbox Rename mbox according to actions instead of 'mbox0' and 'mbox1'. The 8195 dsp node, which uses this binding, has not yet been added to the 8195 devicetree.
