I found if eDP_AVDD_1V0 and eDP_AVDD_1V8 are not been power at
RK3288, once trying to enable the pclk clock, the kernel would dead.
This patch would try to enable them first.

The eDP_AVDD_1V8 is used for eDP phy, and the eDP_AVDD_1V0 are used
both for eDP phy and controller.

UPSTREAM: usb: gadget: f_fs: Fix possibe deadlock

When system try to close /dev/usb-ffs/adb/ep0 on one core, at the same
time another core try to attach new UDC, which will cause deadlock as

CHROMIUM: xhci: fix USB3 device undetected after resume

Some xHC controllers (e.g. Rockchip rk3399) integrated in
DWC3 IP, will be powered down in S3, and reinitialized after
resume.

However, if a USB3 device is plugged before system enter S3,
the device will be disconnected after resume because of xHC
lose power. And the device can't be detected again even if
we reinitialize xHC. In this case, CCS and CSC is '0' and
can't reflect the current state of the port, also the link
state stays in Rx.Detect.

So try to do warm reset on resume to reset USB3 device to
the default state, also reset a USB3 link, and re-exchange
link configuration information.

UPSTREAM: ARM: DTS: Fix register map for virt-capable GIC

Since everybody copied my own mistake from the DT binding example,
let's address all the offenders in one swift go.

Most of them got the CPU interface size wrong (4kB, while it should
be 8kB), except for both keystone platforms which got the control
interface wrong (4kB instead of 8kB).

In a few cases where I knew for sure what implementation was used,
I've added the "arm,gic-400" compatible string. I'm 99% sure that
this is what everyone is using, but short of having the TRM for
all the other SoCs, I've left them alone.

FROMLIST: usb: dwc3: add disable u2mac linestate check quirk

This patch adds a quirk to disable USB 2.0 MAC linestate check
during HS transmit. Refer the dwc3 databook, we can use it for
some special platforms if the linestate not reflect the expected
line state(J) during transmission.

When use this quirk, the controller implements a fixed 40-bit
TxEndDelay after the packet is given on UTMI and ignores the
linestate during the transmit of a token (during token-to-token
and token-to-data IPGAP).

On some rockchip platforms (e.g. rk3399), it requires to disable
the u2mac linestate check to decrease the SSPLIT token to SETUP
token inter-packet delay from 566ns to 466ns, and fix the issue

cpufreq: dt: support checking initial rate

Bootloader or kernel sets CPU frequency to an initial value before cpufreq
starts on rockchip platform, if cpu's opp table is modified to a specified
value, it will cause an issue.

For example, the initial frequency is 816MHz and voltage set by hardware
is 900mV:
1. there is only one opp whose frequency is 816MHz and voltage is 850mV
in opp table list, as they frequency is equal, the voltage will not be
changed, it is still 900mV and a little too large relative to 850mV.
2. there is only one opp whose frequency is 1200MHz and voltage is 1100mV
in opp table list, as it doesn't set voltage to 1100mV before set frequency
to 1200MHz in the dev_pm_opp_set_rate function, the initial voltage 900mV
cann't supply for 1200MHz, the system crash.

phy: rockchip-inno-usb2: tuning USB 2.0 squelch detection threshold

According to USB 2.0 Spec Table 7-7, the High-speed squelch
detection threshold Min 100mV and Max 150mV, and we set USB
2.0 PHY0 and PHY1 squelch detection threshold to 150mV by
default, so if the amplitude of differential voltage envelope
is < 150 mV, the USB 2.0 PHYs envelope detector will indicate
it as squelch.

On RK3399 box, if we connect usb device with a 4 meter cable,
we can see that the impedance of U2 cable is too big according
to the eye-diagram test report, and this cause serious signal
attenuation at the end of receiver, the amplitude of differential
voltage falls below 150mV.

This patch aims to reduce the PHY0 and PHY1 otg-ports squelch
detection threshold to 125mV (host-ports still use 150mV by
default), this is helpful to increase USB 2.0 PHY compatibility.
