The second CAN port cannot be used without hardware modification

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.

This implies that all unused voltage rails for Vayu can never be

on other domains and increased leakage and power-on-hour impacts.

Add MMC1 and 2 nodes. MMC1 is SDcard and MMC2 is eMMC.

NOTE on MMC1 card detect: Ideally, we should be using in-built SDCD
support, but we dont have it yet. So, use the fact that control module
of DRA7 is setup such that no matter what mode one configures it, GPIO
option is always hardwired in - use GPIO mode for SDcard detection.

[peter.ujfalusi@ti.com]
The power line feeding the SD card is also used by other devices on the EVM.
Use generic name instead of mmc2_3v3 so when other devices want to use the
same regulator it will look a bit better.
