SiS 761 chipset does not support AGP cards but has AGP capability (for
the onboard video). At least PC Chips A31G board using this chipset has
an AGP-like AGPro slot that's wired to the PCI bus. Enabling AGP will
fail (GPU lockup and software fbcon, X11 hangs).
Add support for matching just the host bridge in nvkm_device_agp_quirks
and add entry for SiS 761 with mode 0 (AGP disabled).

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

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

This commit adds MIDI functionality to capture/playback MIDI messages
from/to physical MIDI ports. These messages are transferred in isochronous
packets.
When no substreams request AMDTP streams to run, this driver starts the
streams at current sampling rate. When other substreams start at different
sampling rate, the streams are stopped temporarily, then start again at
requested sampling rate. This operation can generate missing MIDI bytes,
thus it's preferable to start PCM substreams at favorite sampling rate in
advance.

These ports are added in later commits.

In Digi 002/003 protocol, MIDI messages are transferred in the last data
channel of data blocks. Although this data channel has a label of 0x80,
it's not fully MIDI conformant data channel especially because the Counter
field always zero independently of included MIDI bytes. The 4th byte of
the data channel in LSB tells the number of included MIDI bytes. This byte
also includes the number of MIDI port. Therefore, the data format in this
data channel is:
* 1st: 0x80 as label
* 2nd: MIDI bytes
* 3rd: 0 or MIDI bytes
* 4th: the number of MIDI byte and the number of MIDI port
This commit adds support of MIDI messages in data block processing layer.
Like AM824 data format, this data channel has a capability to transfer
more MIDI messages than the capability of phisical MIDI bus. Therefore, a
throttle for data rate is required to prevent devices' internal buffer to
overflow.
