When playing NLPCM audio, such as AC3, HDMI is pluged in, it's
better to reset audio fifo and sync audio clock by reselect
audio input interface. Or sink may not recognize NLPCM format.

On LVDS buses, usually each sample is transferred serialized in seven
time slots per pixel clock, on three (18-bit) or four (24-bit) differential
data pairs at the same time. The remaining bits are used for control signals
as defined by SPWG/PSWG/VESA or JEIDA standards. The 24-bit RGB format
serialized in seven time slots on four lanes using JEIDA defined bit mapping
will be named MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA, for example.

xHC can generate two events for a short transfer if the short TRB and
last TRB in the TD are not the same TRB.
The driver will handle the TD after the first short event, and remove
it from its internal list. Driver then incorrectly prints a warning
for the second event:
"WARN Event TRB for slot x ep y with no TDs queued"
Fix this by not printing a warning if we get a event on a empty list
if the previous event was a short event.

(cherry picked from commit e4ec40ec4b)
This patch adds a kernel node "u3phy_mode" in sysfs to config
USB 2.0 only or USB 2.0/3.0 mode for combphy USB mode. This
method is only used for USB Host mode.
It needs to reinit the xHCI when switch between USB 2.0 only
and USB 2.0/3.0 mode dynamically. In order to reinit the xHCI,
we use the "otg_mode" node in sysfs to remove/add xHCI HCD.
<How to use>
1. Default is USB 3.0 OTG mode, config to USB 2.0 only mode
echo u2 > /sys/devices/platform/<u3phy dev name>/u3phy_mode
echo host > /sys/devices/platform/<u2phy dev name>/otg_mode
2. Default is USB 3.0 Host mode, config to USB 2.0 only mode
echo otg > /sys/devices/platform/<u2phy dev name>/otg_mode
echo u2 > /sys/devices/platform/<u3phy dev name>/u3phy_mode
echo host > /sys/devices/platform/<u2phy dev name>/otg_mode
3. Default is USB 2.0 only Host mode, config to USB 3.0 mode
echo otg > /sys/devices/platform/<u2phy dev name>/otg_mode
echo u3 > /sys/devices/platform/<u3phy dev name>/u3phy_mode
echo host > /sys/devices/platform/<u2phy dev name>/otg_mode

This patch adds support for the ultrasonic ranger srf04 of devantech.
This device is measuring the distance of objects in a range between 1 cm
and 3 meters and a theoretical resolution of 3 mm.
There are two GPIOs used:
- trigger: set as output to the device when the measurement should start
- echo: set by the device when the ultrasonic wave is sent out and reset
when the echo is recognized; this needs to be an interrupt input
The time between setting and resetting the echo pin is the time the
waveform needed for one round trip. This time is recorded in the interrupt
handler.
The distance is calculated in the read function by using the ultrasonic
speed at 20 degrees celsius which is about 343 m/s.

Innosilicon LVDS/TTL PHY implements LVDS TIA/EIA protocol.
Normally, Innosilicon LVDS/TTL PHY contains four 7-bit
parallel-load serial-out shift registers, a 7X clock PLL,
and five Low-Voltage Differential Signaling (LVDS) line drivers
in a single integrated circuit. These functions allow 28 bits
of single-ended LVTTL data to be synchronously transmitted over
five balanced-pair conductors for receipt by a compatible receiver.
In addition, Innosilicon LVDS/TTL PHY could extend from 4 lanes
to N lanes (N is required by the customer). Therefore, the TTL
lines extend respectively.
