From mboxrd@z Thu Jan 1 00:00:00 1970 From: marex@denx.de (Marek Vasut) Date: Sun, 17 Nov 2013 02:20:49 +0100 Subject: [PATCH 3/5] ARM: imx: imx53: Add SATA PHY clock In-Reply-To: <1384651251-5548-1-git-send-email-marex@denx.de> References: <1384651251-5548-1-git-send-email-marex@denx.de> Message-ID: <1384651251-5548-3-git-send-email-marex@denx.de> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add SATA PHY clock which are derived from the USB PHY1 clock. Note that this patch derives the SATA PHY clock from USB PHY1 clock gate so that the SATA driver can ungate both the SATA PHY clock and USB PHY1 clock for the SATA to work correctly.
