The OTG arrangement on the LinkSprite pcDuino v3 Nano is the same as the pcDuino 1/2/3: the OTG port's 5V line is connected directly to the 5V bus (it's not switchable), and the OTG port's ID pin is connected to PH4 on the A20. Tested successfully in both host and device modes. Signed-off-by:

Now that we have axp22x.dtsi describing common axp22x hardware, use it and reference the nodes instead of declaring the whole tree. Also drop the "always-on" from the vdd-gpu regulator, since we don't support the GPU anyway. And add a regulator reference for cpu0. Signed-off-by:

The AXP22x family of PMIC is used with some Allwinner SoCs. This includes the AXP221, AXP221s and AXP223. They differ in the host interface, maximum supply current for DCDC1 regulator, and default voltage and state for various LDO regulators. Also, the AXP221s does not support fine calibration of the battery fuel gauge. This patch adds a dtsi file for all the common bindings for these PMICs. Currently this is just listing all the regulator nodes. The regulators are initialized based on their device node names. Signed-off-by:

The LinkSprite pcDuino v3 Nano's two USB host ports are powered by a single RT9701GB regulator, which has its enable input tied to the A20's PD2 pin, pulled up to 3v3 via a 10k resistor. However, the script.bin that shipped with the device listed PH11 and PH3 as Vbus control pins for the two USB ports. Neither of these are actually connected to anything. Siarhei Siamashka spotted this problem while reviewing the other LinkSprite boards. This patch fixes it by only defining a single regulator, controlled by PD2. Testing shows that the USB ports are now (correctly) only powered up once the USB PHY driver is loaded. Reported-by:

Enable the otg/drc usb controller on the pcDuino1/2 board. Note that the pcDuino1 FEX file from the vendor contains the following information in the [usbc0] section: usb_id_gpio = port:PH04<0><1><default><default> usb_det_vbus_gpio = port:PH05<0><0><default><default> usb_drv_vbus_gpio = port:PB09<1><0><default><0> While the pcDuino2 FEX has: usb_id_gpio = port:PH04<0><1><default><default> usb_det_vbus_gpio = port:PH05<0><0><default><default> usb_drv_vbus_gpio = port:PD02<1><0><default><0> The ID pin is indeed PH4. The PD2 pin can be used to switch power on/off for the USB Type A receptacle on pcDuino2, but it has nothing to do with the MicroUSB OTG receptacle. The VBUS pin of the MicroUSB receptacle is always connected to 5V according to the schematics (both pcDuino1 and pcDuino2) and confirmed by doing some tests on pcDuino2. The PH5 pin is just one of the pins on the J8 expansion header and has nothing to do with USB OTG. The PB9 pin is pulled up and connected to the N_VBUSEN pin of AXP209 PMIC, while the VBUS pin of AXP209 only has a capacitor between it and the ground (this pin is not used for anything else). To sum it up. Only the ID pin (PH4) has a real use. And 5V voltage is always served to the MicroUSB OTG receptacle no matter what is the state of the PB9/PD2 pins. This patch has been tested on pcDuino2 to work fine in a host role with a USB keyboard connected via an OTG cable. It also works fine in a device role (cdc_ether) with a regular Micro-B cable connected to a desktop PC. Signed-off-by: -

The LinkSprite pcDuino2 board is almost identical to the older LinkSprite pcDuino1 board according to the schematic pdf files. So we just include the existing "sun4i-a10-pcduino.dts" file and make the necessary adjustments. Signed-off-by:

The pcDuino1 board does not use any power switches at all for its two USB host ports and the VBUS pins are always connected to 5V. The pcDuino2 board uses the RT9701GB power switch for its single USB host port, but the USB_EN pin (PD2) is pulled up with a 10K resistor. So that the USB power is still enabled by default, resulting in the same behaviour as pcDuino1 if nobody touches the PD2 pin. This minor difference is going to be handled in a follow-up patch, introducing a separate dts file for pcDuino2. The primary reason for this fix is that the current dts file unnecessarily meddles with the PH3 and PH6 pins. But the PH6 pin is available on the Arduino-compatible expansion header and may have a better use for other purposes. This patch fixes the problem and now the PH6 pin can be used with the GPIO sysfs interface. Tested on a pcDuino2 board with a multimeter: echo 230 > /sys/class/gpio/export echo "out" > /sys/class/gpio/gpio230/direction echo 0 > /sys/class/gpio/gpio230/value echo 1 > /sys/class/gpio/gpio230/value USB still works as expected too.

sun7i-a20-bananapi.dts doesn't contain regulator nodes for the AXP209 PMU driver, so add them to allow for voltage-scaling with cpufreq-dt. Also add board-specific OPP to use slightly higher voltages at lower frequencies since Kevin Hilman reported that not all BananaPi boards run stable at the default voltages inherited by sun7i-a20.dtsi.
