The Orange Pi 2 is a SBC based on the Allwinner H3 SoC with a uSD slot,
4 USB ports connected via a USB-2 hub, a 10/100M ethernet port using the
SoC's integrated PHY, Wifi via a RTL8189ETV sdio wifi chip, USB OTG, HDMI,
a TRRS headphone jack for stereo out and composite out, a microphone,
an IR receiver, a CSI connector, 2 LEDs, a 3 pin UART header
and a 40-pin GPIO header.

While still 3.3V, the power of the mmc1 if supplied by an other
regulator.

I do not have schematics for the OPi 2, on the OPi plus schematic the
2 share a regulator. But even if it is another fixed 3.3V regulator,
there is little use in modelling it as a separate regulator when we
cannot control it.
