From mboxrd@z Thu Jan 1 00:00:00 1970 From: w-kwok2@ti.com (WingMan Kwok) Date: Thu, 15 Oct 2015 10:27:10 -0400 Subject: [PATCH] ARM: keystone: dts: add PCI serdes driver bindings Message-ID: <1444919230-30932-1-git-send-email-w-kwok2@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
