Subject: [RFC 1/2] dt-bindings: clk: versaclock5: Add load capacitance properties
Date: Wed, 6 Jan 2021 11:38:59 -0600 [thread overview]
Message-ID: <20210106173900.388758-1-aford173@gmail.com> (raw)
There are two registers which can set the load capacitance for
XTAL1 and XTAL2. These are optional registers when using an
external crystal. Update the bindings to support them.
