Subject: [PATCH 02/10] net: phy: micrel: add device-type abstraction
Date: Wed, 19 Nov 2014 12:59:15 +0100	[thread overview]
Message-ID: <1416398363-32306-3-git-send-email-johan@kernel.org> (raw)
In-Reply-To: <1416398363-32306-1-git-send-email-johan@kernel.org>

Add structured device-type information and support for generic led-mode
setup to the generic config_init callback.

This is a first step in ultimately getting rid of device-type specific
callbacks.
