Subject: [PATCH 1/4] ARM: OMAP2+: dm81xx: Add clkdm and hwmod for SATA
Date: Mon, 13 Mar 2017 17:43:16 +0100	[thread overview]
Message-ID: <1489423399-3824-2-git-send-email-bgolaszewski@baylibre.com> (raw)
In-Reply-To: <1489423399-3824-1-git-send-email-bgolaszewski@baylibre.com>

From: Kevin Hilman <khilman@baylibre.com>

Add the SATA clockdomain (part of CM_DEFAULT) and a hwmod for the SATA
block on dm81xx.

Tested on DM8168 EVM.
