I think the LCD connector on Banana Pi's uses parallel interface,
although the LCD should be an external DT overlay.

Hello,

All the RSB based PMICs support both modes. They start in I2C mode
when cold booted.

I think it starts at a vendor-customized mode. In all PMICs sold
with Allwinner SoCs the mode is predefined to RSB.

In fact many registers in AXPs are vendor-customizable, see
the datasheets.

currently the "x-powers,axp803" binding is "RSB" bus specific as it's
currently only listed in drivers/mfd/axp20x-rsb.c

was there a discussion about supporting both, the "RSB" and I2C bus
for one chip (for example the AXP803) in the past (I couldn't find
anything online)?

No. None of the boards actually use I2C instead of RSB. RSB mode is
initialized by the boot loader. There is no easy way for the kernel to
switch it back.

what about the device-tree bindings in this case?

We can deal with it if someone actually comes up with a practical
case needing it. Otherwise things go untested, which is not what
we want.

In the sample batch (1.2V fixed voltage) the card detect is normal
(PF6 low as inserted), however in the final batch (1.1V/1.3V
switchable) it's inverted at PF6 (high as inserted).

Then just use the final version's.

It can operate in OTG -- you can power the board via the OTG port,
as the VBUS is not gated from 5V at all, so 5V power at VBUS will
power up the board. Yes, it's a bit unsafe, but the board designer
did it.

What will provide the 5v in the first place then if a USB device is
connected to the micro-USB connector?

There're two micro-USB connectors, one is power-only and another is
OTG. The Vbus of these two connectors are connected together, so
the external USB device will be powered just by the power input
from the power-only USB port.

[PATCH] ARM: sun8i: h2+: add support for Banana Pi M2 Zero board

2017-11-01 Thread Icenowy Zheng

Banana Pi M2 Zero board is a H2+-based board by Sinovoip, with a form
factor and GPIO holes similar to Raspberry Pi Zero.

It features:
- Allwinner H2+ SoC
- Single-chip (16-bit) 512MiB DDR3 DRAM
- Ampak AP6212 Wi-Fi/Bluetooth module
- MicroSD slot
- Two MicroUSB Type-B ports (one can only be used to power the board and
  the other features OTG functionality)
- Two keys, a reset and a GPIO-connected key.
- HDMI Type-C (miniHDMI) connector connected to the HDMI part of H2+.
- CSI connector to connect the camera sensor provided by Sinovoip.
