[PATCH v6 2/2] ARM: dts: am335x: add am335x-sancloud-bbe board support

From: Koen Kooi
Date: Tue Jul 17 2018 - 02:52:44 EST

The "Beaglebone Enhanced" by Sancloud is based on the Beaglebone Black,
but with the following differences:

* Gigabit capable PHY
* Extra USB hub, optional i2c control
* lps3331ap barometer connected over i2c
* MPU6050 6 axis MEMS accelerometer/gyro connected over i2c
* 1GiB DDR3 RAM
* RTL8723 Wifi/Bluetooth connected over USB

Tested on a revision G board.

v6: Generic nodename for usbhub, was missed in v5
v5: generic nodenames (e.g. mpu6050 -> accelerometer), lowercase hex numbers
v4: No changes
v3: Drop oppnitro-1000000000, not needed on the versions Sancloud is using
v2: * Add missing #include <dt-bindings/interrupt-controller/irq.h>
* Fix Barometer compatible string
v1: Initial submission
