Subject: [PATCH robh next] dt-bindings: bus: add Broadcom CRU
Date: Tue,  9 Mar 2021 15:22:41 +0100	[thread overview]
Message-ID: <20210309142241.16259-1-zajec5@gmail.com> (raw)

From: Rafał Miłecki <rafal@milecki.pl>

CRU is a block used in Northstar devices. It can be seen in the
bcm5301x.dtsi and this binding documents its proper usage.
