commit 9066e151c37950af92c3be6a7270daa8e8063db9 upstream.
Since commit 488dac0c9237 ("libfs: fix error cast of negative value in
simple_attr_write()"), the EINJ debugfs interface no longer accepts
negative values as input. Attempt to do so will result in EINVAL.Fixes: 488dac0c9237 ("libfs: fix error cast of negative value in simple_attr_write()")

commit a11174952205d082f1658fab4314f0caf706e0a8 upstream.
The data node reference documentation was missing a package that must
contain the property values, instead property name and multiple values
being present in a single package. This is not aligned with the _DSD
spec.Fix it by adding the package for the values.
Also add the missing "reg" properties to two numbered nodes.

…ierry.reding/linux-pwm
Pull pwm updates from Thierry Reding:
"This contains mostly various fixes, cleanups and some conversions to
the atomic API. One noteworthy change is that PWM consumers can now
pass a hint to the PWM core about the PWM usage, enabling PWM
providers to implement various optimizations.There's also a fair bit of simplification here with the addition of
some device-managed helpers as well as unification between the DT and
ACPI firmware interfaces"* tag 'pwm/for-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: (50 commits)

Merge the ACPI PCI topic branch depended on by the following material.
-
The ACPI_DEBUG_PRINT() and ACPI_EXCEPTION() macros are used for
message printing in the ACPICA code and they should not be used
elsewhere. Special configuration (either kernel command line or
sysfs-based) is needed to see the messages printed by them and
the format of those messages is also special and convoluted.For this reason, replace all of the ACPI_DEBUG_PRINT() and
ACPI_EXCEPTION() instances in the ACPI processor driver with
corresponding dev_*(), acpi_handle_*() and pr_*() calls depending
on the context in which they appear.Also drop the ACPI_PROCESSOR_COMPONENT definition that is not going

For "fixed" PCI devices, such as chips directly soldered
on the main board (ethernet, Wi-Fi, serial ports, etc.),
it is possible to find an ACPI enumeration.This allows to add useful properties to these devices.
Just for an example: the property "gpio-line-names" can be
added to the pins of a GPIO expander on the PCI bus.In order to find the ACPI name of a PCI device, it's necessary
to disassemble the BIOS ACPI tables (in particular the DSDT)
and also to analyze the PCI bus topology of the board.This patch, with a practical example, show how to do this.
