Subject: [PATCH v3 05/19] phy: mvebu-cp110-comphy: Add RXAUI support

From: Miquel Raynal <[email-masked]>
Date: Wed, 31 Jul 2019 14:21:12 +0200

From: Grzegorz Jaszczyk <[email-masked]>

Add support for RXAUI mode by adding an entry in the COMPHY modes list.

There is no user for this mode yet so we can enforce an up-to-date
firmware and return an error otherwise without breaking anywone.

[[email-masked]: adapt the content to the mainline driver]
