Subject: [PATCH 1/7] arm64: zynqmp: Add support for Xilinx zcu100-revC
Date:   Fri, 19 Jan 2018 13:55:40 +0100
Message-Id: <7dd5614c878adb30e38caf4002921c0ca995329c.1516366474.git.michal.simek@xilinx.com>

References: <cover.1516366474.git.michal.simek@xilinx.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This board has 2GB of memory, i2c, sd, wifi sdio, spis, uarts, display
port and usbs.
Board is using fixed clocks because clock driver hasn't been merged yet.
