Allow the mockup driver to be probed via the device tree without any
module parameters, allowing it to be used to configure and test higher
level drivers like the leds-gpio driver and corresponding userspace
before actual hardware is available.

A bus lock [1] is acquired either through split locked access to
writeback (WB) memory or by using locks to uncacheable (UC) memory
(e.g. direct device assignment). This is typically >1000 cycles slower
than an atomic operation within a cache line. It also disrupts performance
on other cores.

A few issues about sprd watchdog driver were found recently, this
patchset would fix them.

* Added Reviewed-by from Guenter Roeck;
* Abandon original patch 2, add a new patch to use usleep_range() instead of

* Revised the max times of loop, also

This oops is caused by a wrong chip_data and it is because plic_irq_unmask
uses irq_get_chip_data(irq_data->irq) to get the chip_data. However it may
get another irq_data with the same irq_data->irq if it is hierarchy.
In this case, it will get irq_data of sifive_gpio_irqchip instead of
plic_chip

Do GC before shutdown -> delete IO Q -> shutdown from host -> breakup GC ->

SRAM -> over program

The Allwinner V3 and S3 can use PG6/7 as RX/TX for UART1. Since no other
functions are assigned to those pins, they are a convenient choice for
a debugging or application UART.
This is specific to V3/S3 as the V3s's non-BGA package did not have
those pins.

Check whether the hypervisor reported the correct C-bit when running as
an SEV guest. Using a wrong C-bit position could be used to leak
sensitive data from the guest to the hypervisor.
The check function is in arch/x86/kernel/sev_verify_cbit.S so that it
can be re-used in

When SEV is enabled the kernel requests the C-Bit position again from
the hypervisor to built its own page-table. Since the hypervisor is an
untrusted source the C-bit position needs to be verified before the
kernel page-table is used.
Call the sev_verify_cbit() function
