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.

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.

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.

This allows voltage-scaling with cpufreq-dt. The reliability of voltage-scaling has been checked by reducing the voltage of all operating points by 0.025V (for extra safety headroom) and running libjpeg-turbo decoding tests on 5 pcDuino2 boards. It means that the standard sun4i voltages should be perfectly fine too.

The hummingbird A31 has 2 rtc devices available: one in the SoC, and a pcf8563 external rtc on i2c2. For some unknown reason, the onboard backup battery alone can not supply enough power to the internal rtc. When external power is removed, the internal rtc would reset. Hence we want to use the external one by default. Add aliases for the rtc devices with the external one as rtc0.

This commits adds a generic dts file for q8 formfactor a13 based tablets. The tablets ship in many variants, with the difference mainly being the touchscreen controller / accelerometer / wifi chip used. The wifi is USB based, and thus not listed in devicetree. The touchscreen controller / accelerometer may turn out to be a problem once we add support for those. We can either do something with devicetree overlays, or add sun5i-a13-<touchscreen>-<accelerometer>.dts files. The latter is what the android mod community is doing with firmware images. This dts was tested with an a13 q8 tablet with a pcb labelled: "94V-0", silead gsl1680 touchscreen controller and a mc32x0 accelerometer.
