Subject: [PATCH v4 2/6] dt-bindings: audio-graph-card: Add plls and sysclks properties
Date: Fri, 8 Jan 2021 16:04:57 +0000 [thread overview]
Message-ID: <20210108160501.7638-3-rf@opensource.cirrus.com> (raw)
In-Reply-To: <20210108160501.7638-1-rf@opensource.cirrus.com>
The audio-graph-card driver has properties for configuring the clocking
for DAIs within a component, but is missing properties for setting
up the PLLs and sysclks of the component.
This patch adds the two new properties 'plls' and 'sysclks' so that the
audio-graph-driver can fully configure the component clocking.
