Subject: [PATCH] arm64: dts: stingray: use NUM_SATA to configure number of sata ports
Date:   Fri, 18 May 2018 11:34:06 -0700
Message-Id: <1526668446-20048-1-git-send-email-scott.branden@broadcom.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Move remaining sata configuration to stingray-sata.dtsi and enable
ports based on NUM_SATA defined.
Now, all that needs to be done is define NUM_SATA per board.
