The dp_out_en is config as take effect by vsync signal. When disable
the output, it will do some thing as follow:
1. clean dp_out_en bit in vop.
2. disable dp video stream;
3. disable dp link clk.
If it not wait clean dp_out_en bit take effect, the link clk may
disable before clean dp_out_en bit, which will cause dp fifo overflow
issue.
When enable the output, though it not has this issue, it's better to
wait set dp_out_en bit take effect to avoid the similar issue in the
future.

The gpio hpd state will be mismatch the real state if the cable
plug before init the dp controller. So it need updage the gpio
hpd state when dp controller init.

According to the DP PHY CTS v1.2b 3.2.3 and 3.3.3 chapters, the
PreEmphasis Level Test Pattern(PLTPAT), which also was called
80-bit custom pattern, should be:
1111100000 1111100000 1111100000 1111100000
1111100000 1111100000 1111100000 1111100000
It is used to verify the HBR2 in "Non Pre-Emphasis Level Verification
Testing" and "Pre-Emphasis Level Verification and Maximum Pk-Pk
Differential Voltage Testing".
Without this patch, the PLTPAT pattern is incorrect.

Since the report buffer is used by all kinds of drivers in various ways, let's
zero-initialize it during allocation to make sure that it can't be ever used
to leak kernel memory via specially-crafted report.

When an eMMC error occurs due to changes in hardware conditions
(such as temperature, voltage, etc.), it may not return to normal
without reinitializing the eMMC. In this case, adding hardware
reset and reinitialization can solve the problem.

1. Core component of a new driver for InvenSense ICM-42670 devices.
It includes registers definition, main probe/setup, and device
utility functions.
2. Add SPI driver for InvenSense ICM-42670 devices.
3. Add I2C driver for InvenSense ICM-42670 devices.
The ICM-42670-P is a high performance 6-axis MEMS MotionTracking
device that combines a 3-axis gyroscope and a 3-axis accelerometer.
It has a configurable host interface that supports I3CSM, I2C, and
SPI serial communication, features up to 2.25 Kbytes FIFO
and 2 programmable interrupts with ultra-lowpower wake-on-motion
support to minimize system power consumption
