726806ad9b ARM: dts: am57xx-beagle-x15: Fix USB2 mode
On this board USB2 is meant to be used as peripheral only.
The ID pin for USB2 is hardwired HIGH.

f60db98eaa ARM: dts: am57xx-beagle-x15: Add extcon nodes for USB
On this EVM, the USB cable state has to be determined via the
ID pin tied to a GPIO line. We use the gpio-usb-extcon driver
to read the ID pin and the extcon framework to forward
the USB cable state information to the USB driver so the
controller can be configured in the right mode (host/peripheral).

NOTE: the ports on this board cannot switch roles. They are
configured either host or peripheral by hardwiring the
respective ID pins.

7a03f2c08d ARM: dts: am57xx-beagle-x15: Add GPIO controlled fan node
TPS gpio now controls a 5v 500mA TL5209 regulator which may be supply
a fan (such as AFB02505HHB) over J1 connector for various purposes.
Provide device tree node to enable the same.

a75dacf820 ARM: dts: am57xx-beagle-x15: Add dual ethernet
Add CPSW DT binding to beagle X15 DTS in order to
get ethernet working with this board.

Note that we're also adding sleep state which will
place all pins in mux mode 15 - which means "driver
off" - thus conserving power.

5a0f93c657 ARM: dts: Add am57xx-beagle-x15
BeagleBoard-X15 is the next generation Open Source Hardware
BeagleBoard based on TI's AM5728 SoC featuring dual core 1.5GHz A15
processor. The platform features 2GB DDR3L (w/dual 32bit busses),
eSATA, 3 USB3.0 ports, integrated HDMI (1920x1080@60), separate LCD
port, video In port, 4GB eMMC, uSD, Analog audio in/out, dual 1G
Ethernet.

For more information, refer to:
BeagleBoard-X15 Wiki:
http://www.elinux.org/Beagleboard:BeagleBoard-X15

AM5728 is part of the Sitara product family whose additional details
will be available: http://www.ti.com/lsds/ti/arm/overview.page

Technical Reference Manual for AM5728 is public domain at:
http://www.ti.com/lit/spruhz6

Just add basic support for the moment, the following updates are needed:
  i)	Ethernet - depends on SoC dts fixes
  ii)	USB Client (USB2) - depends on GPIO extcon
  ii)	HDMI - additional driver fixes pending
  iii)	Audio - additional driver fixes pending

NOTE:
AM5728 Data Manual (SPRS915L - August 2014) section 4.1.1 states: "All
unused power supply balls must be supplied with the voltages specified
in the Section 5.2, Recommended Operating Conditions". This implies
that all unused voltage rails for AM5728 can never be switched off even
if the hardware blocks inside that voltage domain is unused. Switching
off these unused rails may result in stability issues on other domains
and increased leakage and power-on-hour impacts.
