The combphy_u3_cp_test() is used for USB3 compliance test,
and it depends on the cp_test of phy_ops which will be
dropped later, so we remove combphy_u3_cp_test directly.
As a side effect, we need to use io commands to set the
USB3 enter compliance test mode instead of host_testmode
for RK1808 USB3 combphy.

This patch remove debugfs directory and host_testmode which
cause the following error:
ERROR: "xhci_set_link_state" [drivers/usb/dwc3/dwc3-rockchip-inno.ko] undefined!
We remove the code of host_testmode directly, because it
depends on the phy_cp_test() which will be dropped later.
As a side effect, we need to use io commands to set the
DWC3 Host enter compliance test mode instead of host_testmode
for RK3328 USB3.

When I test the uac gadget function, I find that the uac
gadget out transfer may stop expectedly and the alsa buffer
will be empty which results to input/output error.
In some cases, we will get an endpoint event
DWC3_DEPEVT_XFERINPROGRESS and the event status is
DEPEVT_STATUS_MISSED_ISOC, and the original code try to issue
an EndTransfer command. After the EndTransfer is completed,
we will get a XferNotReady event. However, it will fail to
giveback the req to the udc gadget driver due to an additional
request unmap operation.
To fix this problem, this patch return directly in kick transfer
if there are isochronous endpoints and retry to transfer next time.

There are some differences between hardware V12 and v10
1.Power:
The buck1 of rk809 supplies power to NPU and vepu
The discrete power supplies power to logic
2.Reset signal of camera:
The reset signal of csi rx0 is control by gpio1_D5,
The reset signal of csi rx1 is control by gpio2_A0.

The USB2.0 OTG PHY of RV1126/1109 which is designed for lower power
consumption provides only 8.8mA current source on DM. Multiplied
by 45 Ohm host termination resistance, voltage is about 400mV.
If the threshold voltage of host is greater than 400mV, the high
speed handshake will fail and SoC communicate at full speed. So
swing calibration is necessary.
We use gpio to control the 220 Ohm pull-up resistor to provide additional
current. Experiments show that the voltage of chirpK can be increases
to about 600mV.

This patch will enable id interrupt for otg port when the property
vbus-always-on is set in dts.
If vbus is always on, bvalid interrupt won't make sense and be
disabled. But we cat change id state to switch drd mode by software.

By bypass charge detect module, about 140uA current can be saved
on USB_AVDD_1V8 power supply when suspend. Notice that bandgap
current can not be turned off, so there is still about 165uA
current.
This patch also remove the tuning in phy resuming, because the power
of phy is always on and registers does not need to be configured
again.

RK1000 is a digital-analog mixed chip which has tve output function.
RK1000's registers can be written and read through I2C interaface.
Because RK1000's I2C need dclk and mclk, RK1000 TVE should be registered
after RK1000 CORE.
