All chips of this series with published datasheets support IIN, PIN, and
STATUS_INPUT PMBus commands. Per TI Power Management Forum, "TPS53679 and
TPS53681 have the same PMBus command set". There is no reason to believe
that this does not apply to TPS53688. Let's assume that this is correct
and add support for IIN, PIN, and STATUS_INPUT to TPS53679 and TPS53688
to simplify adding support for more chips of the same series.

At the same time, drop reporting VIN on channel 2. On chips with published
datasheets this voltage is identical to the voltage reported on channel 1,
and there is no reason to believe that this is different for TPS53679 and
TPS53888.

Chip specific support will be needed in the driver to be able to
support additional chips of the same series. Add support for it
to the driver.

To simplify adding support for more chips, call identification code
from the probe function. This lets us use a single structure for common
elements of struct pmbus_driver_info, thus reducing code size as support
for more chips is added.

Some PMBus chips support multiple phases, and report telemetry such
as input current, output current, or temperature for each phase.
Add support for such chips to the PMBus core.

Start with a maximum of 8 phases per page, and assume that supported
sensors per phase are similar for all pages. Only support per-phase
telemetry attributes, no limits or alarms.

As part of this patch, set the initial page variable to 0xff to ensure
that the page is updated when the first page command is issued. Also
only issue page commands if the chip supports more than one page.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertenly introduced[3] to the codebase from now on.

This issue was found with the help of Coccinelle.

Use a bit map to describe if temperature channels are supported,
and use it for all temperature channels. Use a separate flag,
independent of Tdie support, to indicate if the system is running
on a Ryzen CPU.
Signed-off-by: Guenter Roeck <linux@roeck-us.net>

Traditionally, the temperature displayed by k10temp was Tctl.
On Family 17h CPUs, Tdie was displayed instead. To reduce confusion,
Tctl was added later as second temperature. This resulted in Tdie
being reported as temp1_input, and Tctl as temp2_input. This is
different to non-Ryzen CPUs, where Tctl is displayed as temp1_input.
Swap temp1_input and temp2_input on Family 17h CPUs, such that Tctl
is now reported as temp1_input and Tdie is reported as temp2_input,
to align with other CPUs, streamline the code, and make it less
confusing. Coincidentally, this also aligns the code with its
documentation, which states that Tdie is reported as temp2_input.

The purpose of this IP Core is to control the fan used for the cooling of a
Xilinx Zynq Ultrascale+ MPSoC without the need of any external temperature
sensors. To achieve this, the IP core uses the PL SYSMONE4 primitive to
obtain the PL temperature and, based on those readings, it then outputs
a PWM signal to control the fan rotation accordingly.

Pull ARM SoC fixes from Olof Johansson:
 "We've been accruing these for a couple of weeks, so the batch is a bit
  bigger than usual.

  Largest delta is due to a led-bl driver that is added -- there was a
  miscommunication before the merge window and the driver didn't make it
  in. Due to this, the platforms needing it regressed. At this point, it
  seemed easier to add the new driver than unwind the changes.

  Besides that, there are a handful of various fixes:

   - AMD tee memory leak fix

   - A handful of fixlets for i.MX SCU communication

   - A few maintainers woke up and realized DEBUG_FS had been missing
     for a while, so a few updates of that.

  ... and the usual collection of smaller fixes to various platforms"

There is a recipe to deadlock the kernel: submit a timeout sqe with a
linked_timeout (e.g.  test_single_link_timeout_ception() from liburing),
and SIGKILL the process.

Then, io_kill_timeouts() takes @ctx->completion_lock, but the timeout
isn't flagged with REQ_F_COMP_LOCKED, and will try to double grab it
during io_put_free() to cancel the linked timeout. Probably, the same
can happen with another io_kill_timeout() call site, that is
io_commit_cqring().

Pull file locking fixes from Jeff Layton:
 "Just a couple of late-breaking patches for the file locking code. The
  second patch (from yangerkun) fixes a rather nasty looking potential
  use-after-free that should go to stable.

  The other patch could technically wait for 5.7, but it's fairly
  innocuous so I figured we might as well take it"
