Subject: [PATCH v2 2/3] dt-bindings: net: ftgmac100: Describe clock properties
Date: Thu, 10 Oct 2019 12:37:55 +1030 [thread overview]
Message-ID: <20191010020756.4198-3-andrew@aj.id.au> (raw)
In-Reply-To: <20191010020756.4198-1-andrew@aj.id.au>
Critically, the AST2600 requires ungating the RMII RCLK if e.g. NCSI is
in use.
