Subject: [PATCH v3 5/9] wireless: wl1271: make ref_clock configurable by board
Date: Wed, 11 Aug 2010 01:12:24 +0300 [thread overview]
Message-ID: <1281478348-24833-6-git-send-email-ohad@wizery.com> (raw)
In-Reply-To: <1281478348-24833-1-git-send-email-ohad@wizery.com>
The wl1271 device is using a reference clock that may change
between board to board.
Make the ref_clock parameter configurable by the board
files that set up the device, instead of having a hard coded
value in the driver source itself.
