Subject: [PATCH 09/25] phy: berlin-sata: Move PHY_BASE into private data struct
Date: Thu, 27 Nov 2014 11:56:01 +0530	[thread overview]
Message-ID: <1417069577-1169-10-git-send-email-kishon@ti.com> (raw)
In-Reply-To: <1417069577-1169-1-git-send-email-kishon@ti.com>

From: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>

Currently, Berlin SATA PHY driver assumes PHY_BASE address being
constant. While this PHY_BASE is correct for BG2Q, older BG2 PHY_BASE
is different. Prepare the driver for BG2 support by moving the phy_base
into private driver data.
