The prescaler works as parent rate divided by (PRES + 1) (is_pres_direct == 1)
It does not work in the way of parent rate shifted to the right by (PRES + 1),
which means division by 2^(PRES + 1) (is_pres_direct == 0)
Thus is_pres_direct must be enabled for this SoC, to make the right computation.

Sometimes clk drivers are attached to devices which are children of a
parent device that is connected to a node in DT. This happens when
devices are MFD-ish and the parent device driver mostly registers child
devices to match against drivers placed in their respective subsystem
directories like drivers/clk, drivers/regulator, etc. When the clk
driver calls clk_register() with a device pointer, that struct device
pointer won't have a device_node associated with it because it was
created purely in software as a way to partition logic to a subsystem.

This causes problems for the way we find parent clks for the clks
registered by these child devices because we look at the registering
device's device_node pointer to lookup 'clocks' and 'clock-names'
properties. Let's use the parent device's device_node pointer if the
registering device doesn't have a device_node but the parent does. This
simplifies clk registration code by avoiding the need to assign some
device_node to the device registering the clk.

In Exynos542x/5800 SoCs, the G3D leaf clocks are located in the G3D power
domain. This is similar to the other hardware modules and their power
domains. However there is one thing specific to G3D clocks hierarchy.
Unlike other hardware modules, the G3D clocks hierarchy doesn't have any
gate clock between the TOP part of the hierarchy and the part located in
the power domain and some SoC internal busses are sourced directly from
the TOP muxes. The consequence of this design if the fact that the TOP
part of the hierarchy has to be enabled permanently to ensure proper
operation of the SoC power related components (G3D power domain and
Exynos Power Management Unit for system suspend/resume).

This patch adds an explicit call to clk_prepare_enable() on the last MUX
in the TOP part of G3D clock hierarchy to keep it enabled permanently to
ensure that the internal busses get their clock regardless of the main
G3D clock enablement status.

This fixes following imprecise abort issue observed on Odroid XU3/XU4
after enabling Panfrost driver by commit 1a5a85c5 "ARM: dts: exynos:

In the above case, the Panfrost driver disables G3D clocks after failure
of getting the needed regulator and return with -EPROVE_DEFER code. This
causes G3D power domain disable failure and then, during second probe
an imprecise abort is triggered due to undefined power domain state.

Lockdep warns about a possible circular locking dependency because using
syscon_node_to_regmap() will make the created regmap get and enable the
first clock it can parse from the device tree. This clock is not needed to
access the registers and should not be enabled at that time.

Use the recently introduced device_node_to_regmap to solve that as it looks
up the regmap in the same list but doesn't care about the clocks.

 - Add missing sentinel for ulp_div_table in clk-imx7ulp driver
 - Fix clk_pll14xx_wait_lock() function which calls into

  clk: imx: clk-imx7ulp: Add missing sentinel of ulp_div_table
  clk: imx: clk-composite-8m: add lock to gate/mux

So far, we walked the orphan list every time a new clock was registered
in CCF. This was fine since the clocks were only referenced by name.

Now that the clock can be referenced through DT, it is not enough:
* Controller A register first a reference clocks from controller B
  through DT.
* Controller B register all its clocks then register the provider.

Each time controller B registers a new clock, the orphan list is walked
but it can't match since the provider is registered yet. When the
provider is finally registered, the orphan list is not walked unless
another clock is registered afterward.

This can lead to situation where some clocks remain orphaned even if
the parent is available.

Walking the orphan list on provider registration solves the problem.

Pull orangefs update from Mike Marshall:
 "orangefs: posix open permission checking...

  Orangefs has no open, and orangefs checks file permissions on each
  file access. Posix requires that file permissions be checked on open
  and nowhere else. Orangefs-through-the-kernel needs to seem posix
  compliant.

  The VFS opens files, even if the filesystem provides no method. We can
  see if a file was successfully opened for read and or for write by
  looking at file->f_mode.

  When writes are flowing from the page cache, file is no longer
  available. We can trust the VFS to have checked file->f_mode before
  writing to the page cache.

  The mode of a file might change between when it is opened and IO
  commences, or it might be created with an arbitrary mode.

  We'll make sure we don't hit EACCES during the IO stage by using
  UID 0"

[ This is "posixish", but not a great solution in the long run, since a
  proper secure network server shouldn't really trust the client like this.
  But proper and secure POSIX behavior requires an open method and a
  resulting cookie for IO of some kind, or similar.    - Linus ]

Pull nfsd updates from Bruce Fields:
 "This is a relatively quiet cycle for nfsd, mainly various bugfixes.

  Possibly most interesting is Trond's fixes for some callback races
  that were due to my incomplete understanding of rpc client shutdown.
  Unfortunately at the last minute I've started noticing a new
  intermittent failure to send callbacks. As the logic seems basically
  correct, I'm leaving Trond's patches in for now, and hope to find a
  fix in the next week so I don't have to revert those patches"

Pull NFS client updates from Trond Myklebust:
 "Highlights include:

  Features:

   - NFSv4.2 now supports cross device offloaded copy (i.e. offloaded
     copy of a file from one source server to a different target
     server).

   - New RDMA tracepoints for debugging congestion control and Local
     Invalidate WRs.

  Bugfixes and cleanups

   - Drop the NFSv4.1 session slot if nfs4_delegreturn_prepare waits for
     layoutreturn

   - Handle bad/dead sessions correctly in nfs41_sequence_process()

   - Various bugfixes to the delegation return operation.

   - Various bugfixes pertaining to delegations that have been revoked.

   - Cleanups to the NFS timespec code to avoid unnecessary conversions
     between timespec and timespec64.

   - Fix unstable RDMA connections after a reconnect

   - Close race between waking an RDMA sender and posting a receive

   - Wake pending RDMA tasks if connection fails

   - Fix MR list corruption, and clean up MR usage

   - Fix another RPCSEC_GSS issue with MIC buffer space"

We had cases in the previous patch where we were sending the security
descriptor context on SMB3 open (file create) in cases when we hadn't
mounted with with "modefromsid" mount option.

Add check for that mount flag before calling ad_sd_context in
open init.
