The description below is already in use for rk3308.dtsi,
but was somehow never added to a document, so add
"rockchip,rk3308-i2s", "rockchip,rk3066-i2s"

One of the rk3308 i2s nodes also has a different dma layout,
so change that as well.

2.21.0
In order to support new EASRC and simplify the code structure,
We decide to share the common structure between them. This bring
a problem that EASRC accept format directly from devicetree, but
ASRC accept width from devicetree.
In order to align with new ESARC, we add new property fsl,asrc-format.
The fsl,asrc-format can replace the fsl,asrc-width, then driver
can accept format from devicetree, don't need to convert it to
format through width.

Both names are already in use in arch/arm64/boot/dts/qcom/sdm845.dtsi.
Also add #address-cells + #size-cells to the q6asm example,

Some devices have a 4-pin headset jack instead of 3-pin microphone jack.
The new boolean nvidia,headset property tells that the Mic Jack represents
the state of a headset microphone. This additional hardware description is
needed because microphone detection procedure differs in a case of a 4-pin
jack from a 3-pin jack.

sent a reversion patch. I had to modify his patch since
reverting at this point broke Orangefs.
Cleanup 1: Christoph Hellwig noticed that we were doing some unnecessary
work in orangefs_flush, so he sent in a patch that removed
the un-needed code.
Cleanup 2: Al Viro told me he had trouble building Orangefs. Orangefs
should be easy to build, even for Al :-). I looked back
at the test server build notes in orangefs.txt, just in case
that's where the trouble really is, and found a couple of
typos and made a couple of clarifications.
Merge Conflict: Stephen Rothwell reported that my modifications to
orangefs.txt caused a merge conflict with orangefs.rst
in Linux Next. I wasn't sure what to do, so I asked,
and Jonathan Corbet said not to worry about it and
just to report it to Linus.

Commit 944d9fec8d ("hugetlb: add support for gigantic page allocation
at runtime") has added the run-time allocation of gigantic pages.
However it actually works only at early stages of the system loading,
when the majority of memory is free. After some time the memory gets
fragmented by non-movable pages, so the chances to find a contiguous 1GB
block are getting close to zero. Even dropping caches manually doesn't
help a lot.
At large scale rebooting servers in order to allocate gigantic hugepages
is quite expensive and complex. At the same time keeping some constant
percentage of memory in reserved hugepages even if the workload isn't
using it is a big waste: not all workloads can benefit from using 1 GB
pages.
The following solution can solve the problem:
1) On boot time a dedicated cma area* is reserved. The size is passed
as a kernel argument.
2) Run-time allocations of gigantic hugepages are performed using the
cma allocator and the dedicated cma area
In this case gigantic hugepages can be allocated successfully with a
high probability, however the memory isn't completely wasted if nobody
is using 1GB hugepages: it can be used for pagecache, anon memory, THPs,
etc.
* On a multi-node machine a per-node cma area is allocated on each node.
Following gigantic hugetlb allocation are using the first available
numa node if the mask isn't specified by a user.
Usage:
1) configure the kernel to allocate a cma area for hugetlb allocations:
pass hugetlb_cma=10G as a kernel argument
2) allocate hugetlb pages as usual, e.g.
echo 10 > /sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages
If the option isn't enabled or the allocation of the cma area failed,
the current behavior of the system is preserved.
x86 and arm-64 are covered by this patch, other architectures can be
trivially added later.
The patch contains clean-ups and fixes proposed and implemented by Aslan
Bakirov and Randy Dunlap. It also contains ideas and suggestions
proposed by Rik van Riel, Michal Hocko and Mike Kravetz. Thanks!

* tag '9p-for-5.7-2' of git://github.com/martinetd/linux:
9p: document short read behaviour with O_NONBLOCK
- support for asynchronous create and unlink (Jeff Layton). Creates
and unlinks are satisfied locally, without waiting for a reply from
the MDS, provided the client has been granted appropriate caps (new
in v15.y.z ("Octopus") release). This can be a big help for metadata
heavy workloads such as tar and rsync. Opt-in with the new nowsync
mount option.
- multiple blk-mq queues for rbd (Hannes Reinecke and myself). When
the driver was converted to blk-mq, we settled on a single blk-mq
queue because of a global lock in libceph and some other technical
debt. These have since been addressed, so allocate a queue per CPU
to enhance parallelism.
- don't hold onto caps that aren't actually needed (Zheng Yan). This
has been our long-standing behavior, but it causes issues with some
active/standby applications (synchronous I/O, stalls if the standby
goes down, etc).
- .snap directory timestamps consistent with ceph-fuse (Luis Henriques)

Merge tag 'ceph-for-5.7-rc1' of git://github.com/ceph/ceph-client
Pull ceph updates from Ilya Dryomov:
"The main items are:
- support for asynchronous create and unlink (Jeff Layton).
Creates and unlinks are satisfied locally, without waiting for a
reply from the MDS, provided the client has been granted
appropriate caps (new in v15.y.z ("Octopus") release). This can be
a big help for metadata heavy workloads such as tar and rsync.
Opt-in with the new nowsync mount option.
- multiple blk-mq queues for rbd (Hannes Reinecke and myself).
When the driver was converted to blk-mq, we settled on a single
blk-mq queue because of a global lock in libceph and some other
technical debt. These have since been addressed, so allocate a
queue per CPU to enhance parallelism.
- don't hold onto caps that aren't actually needed (Zheng Yan).
This has been our long-standing behavior, but it causes issues with
some active/standby applications (synchronous I/O, stalls if the
standby goes down, etc).
- .snap directory timestamps consistent with ceph-fuse (Luis
Henriques)"
* tag 'ceph-for-5.7-rc1' of git://github.com/ceph/ceph-client: (49 commits)
ceph: fix snapshot directory timestamps
ceph: wait for async creating inode before requesting new max size
ceph: don't skip updating wanted caps when cap is stale
ceph: request new max size only when there is auth cap
ceph: cleanup return error of try_get_cap_refs()
ceph: return ceph_mdsc_do_request() errors from __get_parent()
ceph: check all mds' caps after page writeback
ceph: update i_requested_max_size only when sending cap msg to auth mds
ceph: simplify calling of ceph_get_fmode()
ceph: remove delay check logic from ceph_check_caps()
ceph: consider inode's last read/write when calculating wanted caps
ceph: always renew caps if mds_wanted is insufficient
ceph: update dentry lease for async create
ceph: attempt to do async create when possible
ceph: cache layout in parent dir on first sync create
ceph: add new MDS req field to hold delegated inode number
ceph: decode interval_sets for delegated inos
ceph: make ceph_fill_inode non-static
ceph: perform asynchronous unlink if we have sufficient caps
ceph: don't take refs to want mask unless we have all bits
