ARM: dts: sun6i: Add Merrii A31 Hummingbird support
This adds support for the A31 Hummingbird: http://www.merrii.com/en/pla_d.asp?id=172 The Merrii A31 Hummingbird is a development board based on the Allwinner A31 SoC with multiple USB ports through a USB hub chip, a uSD slot, a 10/100/1000M ethernet port, an AP6210 WiFi/BT chip, TV-in, HDMI, VGA, audio in/out ports, and LCD/CSI headers. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> [wens@csie.org: enable usbphy, ehci0, ohci0 for on-board usb hub; add pcf8563 rtc node; add comments for i2c0 and mmc0 pull-ups; correct ethernet phy address to 0x01; drop uart2 (BT chip has no power) and uart3 (no device); use proper commit message] Signed-off-by: Chen-Yu Tsai <wens@csie.org>
