      Merge series "Add frequency / voltage scaling support for IPQ6018 SoC" from Kathiravan T <kathirav@codeaurora.org>:

IPQ6018 SoC uses the PMIC MP5496. SMPA2 and LDOA2 regulator of MP5496
controls the APSS and SDCC voltage scaling respectively. Add support
for the same.

changes since V1:
	- Moved YAML conversion to the last as per Mark's comments

      regulator: lp87565: enable voltage regardless of ENx pin · 81fdcef3
      Luca Ceresoli authored 
      This driver enables outputs by setting bit EN_BUCKn in the BUCKn_CTRL1
register. However, if bit EN_PIN_CTRLn in the same register is set, the
output is actually enabled only if EN_BUCKn is set AND an enable pin is
active. Since the driver does not touch EN_PIN_CTRLn, the choice is left to
the hardware, which in turn gets this bit from OTP memory, and in absence
of OTP data it uses a default value that is documented in the datasheet for
LP8752x, but not for LP8756x.

Thus the driver doesn't really "know" whether it is actually enabling the
output or not.

In order to make sure activation is always driver-controlled, just clear
the EN_PIN_CTRLn bit. Now all activation solely depend on the EN_BUCKn bit.

      Pull SafeSetID update from Micah Morton:
 "Add additional LSM hooks for SafeSetID

  SafeSetID is capable of making allow/deny decisions for set*uid calls
  on a system, and we want to add similar functionality for set*gid
  calls.

  The work to do that is not yet complete, so probably won't make it in
  for v5.8, but we are looking to get this simple patch in for v5.8
  since we have it ready.

  We are planning on the rest of the work for extending the SafeSetID
  LSM being merged during the v5.9 merge window"

      security: Add LSM hooks to set*gid syscalls · 39030e13
      Thomas Cedeno authored 
      The SafeSetID LSM uses the security_task_fix_setuid hook to filter
set*uid() syscalls according to its configured security policy. In
preparation for adding analagous support in the LSM for set*gid()
syscalls, we add the requisite hook here. Tested by putting print
statements in the security_task_fix_setgid hook and seeing them get hit
during kernel boot.

  There are four reverts in total, but three of them are followup
  cleanups needed to revert a43a67a2 cleanly. The result is the
  buffer head based implementation of direct io.

      Revert "btrfs: switch to iomap_dio_rw() for dio" · 55e20bd1
      David Sterba authored 
      This reverts commit a43a67a2.

This patch reverts the main part of switching direct io implementation
to iomap infrastructure. There's a problem in invalidate page that
couldn't be solved as regression in this development cycle.

The problem occurs when buffered and direct io are mixed, and the ranges
overlap. Although this is not recommended, filesystems implement
measures or fallbacks to make it somehow work. In this case, fallback to
buffered IO would be an option for btrfs (this already happens when
direct io is done on compressed data), but the change would be needed in
the iomap code, bringing new semantics to other filesystems.

Another problem arises when again the buffered and direct ios are mixed,
invalidation fails, then -EIO is set on the mapping and fsync will fail,
though there's no real error.

There have been discussions how to fix that, but revert seems to be the
least intrusive option.
