Use the new dmaengine_synchronize() function to make sure that all complete
callbacks have finished running before the runtime data, which is accessed
in the completed callback, is freed.
This fixes a long standing use-after-free race condition that has been
observed on some systems.

kref_init initializes the reference count to 1, not 0. This additional
reference is never released since the conversion to reference counters.
As a result, uvc_delete is not called anymore when UVC cameras are
disconnected.
Fix this by adding an additional kref_put in uvc_disconnect and in the
probe error path. This also allows to remove the temporary additional
reference in uvc_unregister_video.

When RK3399 work as a host connect to RK1808 work as a ep:
1. RK3399 pcie DO NOT enter L2 state when suspend, because RK1808 won't
send the ACK.
2. Hand the link operation to userspace when RK3399 resume
3. Before RK1808 suspend or reboot, RK3399 do following first to break
the link:
echo 0x2 > sys/devices/platform/f8000000.pcie/pcie_reset_ep
4. After RK1808 resumed or booted, RK3399 do following to restart

When switching from another color to yuv422, neither
encoder input color nor encoder output color is rgb.
CSC coeff will be incorrectly selected as
csc_coeff_full_to_limited, which causes the display
turn to green. To solve this problem, choose
csc_coeff_full_to_limited only if the input and output
colors are both RGB.

We need to dynamically resize the TxFIFOs for some cases
where the default values don't match.
Test on RK1808-stick board, configurate the usb with four
functions "rndis, ntb, mass_storage, acm", the default
values of TxFIFOs is:
GTXFIFOSIZ(0) = 0x00000042
GTXFIFOSIZ(1) = 0x00420184
GTXFIFOSIZ(2) = 0x01c60184
GTXFIFOSIZ(3) = 0x034a0184
GTXFIFOSIZ(4) = 0x04ce0184
GTXFIFOSIZ(5) = 0x06520184
GTXFIFOSIZ(6) = 0x07d6002a
The ep6-in is used for acm ep-in which maxpacket is 1024B,
but the default fifo size of ep6-in is only 336B, less than
the length of the ep maxpacket, it cause acm works abnormally.
This patch creates a simple function to allocate enough TxFIFO
space for each of the enabled endpoints.

The early (RK_EXCAVATOR_MAIN_V10_20160627) v10 board had some hardware
issues, for example, pwm regulator even a small miscalculation by hardware
and the emmc can't work on hs400 mode. But there still have someone used
the old v10 boards on their hands.
Anyway, that should support the old v10 board with this patch.

The Linux SDK have a common issue with rk809/rk805/rk817..etc, the
regulator can't be disabled during suspending since the linux config
hadn't enable the CONFIG_PINCTRL_RK805 pinctrl for PMIC.
This config include the rk805/rk809/rk809..pinctrl to control for
pmic. So the related config need be enabled by default.

AFAWK, there are four layers in RK3399's VOPB, and two layers for
RK3399's VOPL.
And RK3399's VOBL has the win0 and win2 layers, the formats they support
as below.
win0:
XR24 AR24 XB24 AB24 RG24 BG24 RG16 BG16 NV12 NV16 NV24 NA12 NA16 NA24
win2:
XR24 AR24 XB24 AB24 RG24 BG24 RG16 BG16
So only win0 layer supports NV12 format (for video decode format),
adjust the overlay for video and primary layer for display.
It didn't care this case if some platforms had handled the display in
application (e.g android), then on the Linux platform, it's hard to handle
the all kinds of cases in Display application, perhaps the linux needn't
this patch fixes it in the future.

The zpos currently configure is the order in vop_win_data array,
which is related to the actual hardware plane.
But in the Linux platform, such as video hardware and camera preview,
it can only be played on the nv12 plane.
So set the order of zpos to PRIMARY < OVERLAY (if have) < CURSOR (if have).
