Emulate NMIs on systems where they are not available by using timer
interrupts on other cpus. Each cpu will use its softlockup hrtimer
to check that the next cpu is processing hrtimer interrupts by
verifying that a counter is increasing.
This patch is useful on systems where the hardlockup detector is not
available due to a lack of NMIs, for example most ARM SoCs.
Without this patch any cpu stuck with interrupts disabled can
cause a hardware watchdog reset with no debugging information,
but with this patch the kernel can detect the lockup and panic,
which can result in useful debugging info.

On RK3588 platform, the USB Host port may miss disconnect
falling edge irq which is used to detect usb device plug in.
This always happens in the following two cases:
1. For RK3588 ARM PC, boot system from U Disk which connected
the USB2 Host port (EHCI & OHCI Controller);
2. For RK3588 EVB, increase the disconnect filer counter to
0xF4240 in the reg USB2PHY_GRF_DIS_CON. That is, the
disconnect rising/falling irq filter time is set to 10ms
depend on the 100MHz pclk.
In this case, we can clear the host_disconnect state depend
on the linestate irq which also means that an usb device is
connecting to the port.

BU18TL82-M supports MIPI DSI and LVDS data
transmission by ROHM's original CDR (Clock Data
Recovery) technology. This chip is the serial interface
transmitter IC of the Clockless Link-BD series.
BU18TL82-M converts the MIPI DSI and LVDS data
stream into Clockless Link format transmit through 2
pairs of differential wires.
BU18RL82-M supports LVDS data transmission by
ROHM's original CDR (Clock Data Recovery) technology.
This chip is serial interface receiver IC of the Clockless
Link-BD series.
BU18RL82-M converts Clockless link stream into a
LVDS format, and transmits through one or two ports of
LVDS.
Flexible Input / Output mode is suitable for a variety of
application interface.

For linestate irq as a wakeup source, we need to reconfigure the
linestate filter value base on 32KHz clk at suspend time, and restore
it to the default when the system resume.
By the way, set the grf to handle the phy status when the system
suspend, which can support the linestate wakeup even the PD of the
USB controller was off for RK3588 OTG1 port.
