This patch adds a method to tuning phy with the following
parameters to improve usb driver strength and increase usb2
compatibility.
1. Set max ODT compensation voltage and current tuning reference.
2. Set max pre-emphasis level.
3. Disable the pre-emphasize in eop state and chirp state
to avoid mis-trigger the disconnect detection and also
avoid hs handshake fail.
We don't enable the phy tuning by default. If you want to
tuning phy, you can add a property "rockchip,u2phy-tuning"
in u2phy node, like this:
&u2phy0 {
rockchip,u2phy-tuning;
};
&u2phy1 {
rockchip,u2phy-tuning;
};

Some platforms (e.g. RK3399 BOX board) otg port connector
interface is not standard, that is a Type-A connector with
vbus always powered on, looks like to work as host mode,
however, the otg port still need to support DRD mode.
In the current code, if otg vbus is always powered on, it
will cause USB2 PHY to detect a floating charger in error
case and power off USB2 PHY. This patch adds a new property
"rockchip,vbus-always-on" to fix this issue. With this patch,
we handle this case as otg host only mode, and avoid to do
charger detection and power off USB2 PHY.

Rockchip USB2 phy provides utmi_avalid and utmi_bvalid for
user to check UTMI vbus status. Generally, both of them can
reflect the vbus status correctly, and the utmi_bvalid has
higher sensitivity, so we select the utmi_bvalid to get vbus
status by default.
But some special SoCs may not provide utmi_bvalid, so we
need to select utmi_avalid in this case.

The squashfs multi CPU decompressor makes use of get_cpu_ptr() to
acquire a pointer to per-CPU data. get_cpu_ptr() implicitly disables
preemption which serializes the access to the per-CPU data.
But decompression can take quite some time depending on the size. The
observed preempt disabled times in real world scenarios went up to 32ms,
causing massive wakeup latencies. This happens on all CPUs as the
decompression is fully parallelized.
So replace CONFIG_SQUASHFS_DECOMP_MULTI_PERCPU by CONFIG_SQUASHFS_DECOMP_MULTI.

Before vop 2.0, the display sub system only
support one RGB/LVDS/eDP/HDMI/MIPI connector
for one vop, so we can find which output interface
should be enabled by output_type(DPI/LVDS/HDMI).
But for the VOP 2.0 display subsystem, we may
have two connector (LVDS/eDP/HDMI/MIPI) of the
same output_type(HDMI0,HDMI1) enabled at same time,
so the output_type is not enough to give the interface
information, we need to know HDMI0 or HDMI1, eDP0 or eDP1
should be enabled.
So we add output interface id here, every connector
driver should set it correctlly to tell vop driver
to enable the corresponding output interface.

Tsadc has a tshut pin which is designed to reset the pmic or soc,
when the temperature inside soc is too high. we should switch off
the tshut function and change the pin to gpio function in reboot
process, eg, software reset. If not, the tsadc module will WRONGLY
pull high the tshut pin during its reset process and then WRONGLY
reset the pmic or soc, which incurred a hardware reset. The hardware
reset will reset everything inside soc, even includes the power on
reason flag, which is set by software before reboot process.
we also change over-temperature protection mode to cru mode,
since the tshut pin have be changed to gpio function.
