Subject: [PATCH] ARM: BCM5301X: Add DT for D-Link DIR-885L
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
It's device based on BCM47094 which is quite similar to BCM4709 except
for higher CPU frequency. This device has 2 flash memories, it boots
from serial one and stores firmware on NAND. Other than that we define
standard stuff like LEDs, buttons and UART.
