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.
