Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.

Pull regulator fixes from Mark Brown:

operates the TPS6287x devices more within the design spec and can
prevent current surges when changing voltages and another more trivial
one for error message formatting"

regulator: TPS6287X: Use min/max uV to get VRANGE
When DSA/IAA device hits a fatal error, the device enters a halt state.
The driver can reset the device depending on Reset Type required by
hardware to recover the device.
Supported Reset Types are:
0: Reset Device command
1: Function Level Reset (FLR)
2: Warm reset
3: Cold reset
Currently, the driver only supports Reset Type 0.
This patch adds support for FLR recovery Type 1. Before issuing a PCIe
FLR command, IDXD device and WQ states are saved. After the FLR command
execution, the device is recovered to its previous states, allowing
the user can continue using the device.

Changing voltage might ignore slew rate and cause a current surge.
With current implementation the driver will get the regulator to change
the voltage range used during run time. According to communication I
have had with Texas Instruments, this is not intended, since the
Dynamic Voltage Scaling in the hardware is only designed to work
within a voltage range. The current implementation will therefore
ignore the slew rate that is defined in devicetree when the voltage
range is changed during use.
The current implementation will always select a voltage in the most
accurate range that can reach that voltage even though multiple ranges
are able to reach that voltage. There are 4 Voltage ranges with the
following reach:
0b00: 0.4-0.71875V (1.25mV step size)
0b01: 0.4-1.0375V (2.5mV)
0b10: 0.4-1.675V (5mV)
0b11: 0.8-3.3V (10mV)
This in practice means that a change from below to above 0.71875V will
use the smallest range(0b00) for the values below and the second
smallest range(0b01) for the voltages above (Up to 1.675V). I have
timed how long it takes to go from below 0.71875V to above. The
increase was 100mV which, with the slew rate set to 1250µV/µs. This
in theory should take 80µs to do. With the current implementation, it
takes 10µs on my hardware. Doing the same test with the slew rate set
to 5000µV/µs, which should take 20µs, also only takes 10µs to do on
my hardware. Not only is this not in line with the technical
specification for the regulator. It also causes a current surge. Which
when calculating the output current, as described in the technical
specification, compared to what I could observe on my hardware the real
output is ~1A higher (~1.2A) than what I calculated it to be(~0.2A).
I tested also transitioning from a bigger to a smaller range, and the
results were the same.
Instead, let's limit the voltage range to a single one, which is in
line with the intended use of the regulator. This is done by looking
up the minimum and maximum requested voltage specified in devicetree.
