Another fix for isochronous transfers on dwc3. This time around, we're
making sure that we use correct PIDs in all transfer sizes.

MSM PHY driver got a fix for the use of devm_regulator_bulk_get() API
which will avoid kernel crashes.

Renesas DRD driver got 3 fixes: a fix on giveback, a fix for proper
controller programming and the removal of set-but-never-used variable.

ASoC: Fixes for v4.13

Quite a few fixes here that have been sent since the merge window, the
biggest one is the fix from Tony for some confusion with the device
property API which was causing issues with the of-graph card. This is
fixed with some changes in the graph API itself as it seemed very likely
to be error prone.

Pull device mapper fixes from Mike Snitzer:

- a few DM integrity fixes that improve performance. One that address
inefficiencies in the on-disk journal device layout. Another that
makes use of the block layer's on-stack plugging when writing the
journal.

- a dm-bufio fix for the blk_status_t conversion that went in during
the merge window.

- a few DM raid fixes that address correctness when suspending the
device and a validation fix for validation that occurs during device
activation.

- a couple DM zoned target fixes. Important one being the fix to not
use GFP_KERNEL in the IO path due to concerns about deadlock in
low-memory conditions (e.g. swap over a DM zoned device, etc).

- a DM DAX device fix to make sure dm_dax_flush() is called if the
underlying DAX device is operating as a write cache.

dm zoned: drive-managed zoned block device target

The dm-zoned device mapper target provides transparent write access
to zoned block devices (ZBC and ZAC compliant block devices).
dm-zoned hides to the device user (a file system or an application
doing raw block device accesses) any constraint imposed on write
requests by the device, equivalent to a drive-managed zoned block
device model.

Write requests are processed using a combination of on-disk buffering
using the device conventional zones and direct in-place processing for
requests aligned to a zone sequential write pointer position.
A background reclaim process implemented using dm_kcopyd_copy ensures
that conventional zones are always available for executing unaligned
write requests. The reclaim process overhead is minimized by managing
buffer zones in a least-recently-written order and first targeting the
oldest buffer zones. Doing so, blocks under regular write access (such
as metadata blocks of a file system) remain stored in conventional
zones, resulting in no apparent overhead.

dm-zoned implementation focus on simplicity and on minimizing overhead
(CPU, memory and storage overhead). For a 14TB host-managed disk with
256 MB zones, dm-zoned memory usage per disk instance is at most about
3 MB and as little as 5 zones will be used internally for storing metadata
and performing buffer zone reclaim operations. This is achieved using
zone level indirection rather than a full block indirection system for
managing block movement between zones.

dm-zoned primary target is host-managed zoned block devices but it can
also be used with host-aware device models to mitigate potential
device-side performance degradation due to excessive random writing.

Zoned block devices can be formatted and checked for use with the dm-zoned
target using the dmzadm utility available at:
