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.

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.

ARM: dts: am57xx-beagle-x15: Add support for rev B1 Latest update to the BeagleBoard-X15 platform (revision B1)[1] updates for allowing UHS SD cards to function with the split of supply to SD card from a dedicated LDO. As a result of this, AM57xx BeagleBoard-X15 now uses gpio2_30 instead of gpio6_28 for HDMI because HDMI_LS_OE should now be switched from GPIO6_28(Y9) to GPIO2_30 (AG8) to avoid a 1.8V GPIO toggling a 3.3V SoC input when the SD card is in UHS 1.8V mode. NOTE: For UHS mode to function, we need full fledged IODelay support in kernel to be functional. IODelay support is yet to be added. Further, It does not make much sense to spin off a new board compatible flag since there is no real functional benefit for the same. Note: Even though production version is supposed to be B1, there is over ~200 boards of previous version (A2)[2] out there which continue to get supported with the existing dts file (to maintain compatibility with existing bootloaders for A2) and the production board is now supported as revb1.
