Subject: [PATCH 1/6] dt-bindings: pci: amlogic,meson-pcie: Add G12A bindings
Date:   Sun,  8 Sep 2019 13:42:53 +0000
Message-Id: <1567950178-4466-2-git-send-email-narmstrong@baylibre.com>
In-Reply-To: <1567950178-4466-1-git-send-email-narmstrong@baylibre.com>
References: <1567950178-4466-1-git-send-email-narmstrong@baylibre.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add PCIE bindings for the Amlogic G12A SoC, the support is the same
but the PHY is shared with USB3 to control the differential lines.

Thus this adds a phy phandle to control the PHY, and sets invalid
MIPI clock as optional for G12A.
