Subject: [PATCH v2 2/3] ARM: dts: imx7d: Add node for PCIe PHY
Date: Tue, 5 Feb 2019 00:17:40 +0000 [thread overview]
Message-ID: <20190205001721.18639-3-tpiepho@impinj.com> (raw)
In-Reply-To: <20190205001721.18639-1-tpiepho@impinj.com>
This adds the PHY as a new node. The PCI-e controller node gains a
phandle property that points to it.
There isn't yet any code in the kernel that uses this device's
registers, but it will be added for a PCIe PLL erratum workaround.
