#1247848 — [PATCH] ARM: keystone: dts: add PCI serdes driver bindings

FromWingMan Kwok <w-kwok2@ti.com>
Date2015-10-15 16:30 +0200
Subject[PATCH] ARM: keystone: dts: add PCI serdes driver bindings
Message-ID<qjRHA-AM-21@gated-at.bofh.it>
This patch adds the required PCI serdes bindings whcih can then be
enabled by setting the corresponding statuses to "ok" in order to
configure and start the PCI serdes.

This patch depends on the updates to the Keystone PCIe host driver
and common serdes driver patch series that is submitted separately.
