The clock IP used on the Maxim PMICs max77686 and max77802 are
same. The configuration of clock register is also same except
the number of clocks.
Part of common code utilisation, there is 3 files for these chips
clock driver, one for common and two files for driver registration.
Combine both drivers into single file and move common code into
same common file reduces the 2 files and make max77686 and max77802
clock driver in single fine. This driver does not depends on the
parent driver structure. The regmap handle is acquired through
regmap APIs for the register access.
This combination of driver helps on adding clock driver for different
Maxim PMICs which has similar clock IP like MAX77620 and MAX20024.

Before commit 0861e5b8cf (clk: Add clk_hw OF clk providers,
2016-02-05) __of_clk_get_from_provider() would return an error
pointer of the provider's choosing if there was a provider
registered and EPROBE_DEFER otherwise. After that commit, it
would return EPROBE_DEFER regardless of whether or not the
provider returned an error. This is odd and can lead to behavior
where clk consumers keep probe deferring when they should be
seeing some other error.
Let's restore the previous behavior where we only return
EPROBE_DEFER when there isn't a provider in our of_clk_providers
list. Otherwise, return the error from the last provider we find
that matches the node.

These clocks are the ones which will be used as source for the
peripherals of the Armada 3700 SoC. On this SoC there is two blocks of
clocks: the North bridge one and the South bridge one.
Most of them are gatable. Most of the time their rate are their parent
rated divided by a ratio depending of two registers. Their parent can be
choose between the TBG clocks for most of them.
However, some of them can't choose their parent or directly depend of the
xtal clocks. Other ones do not use exactly the same pattern to find the
ratio between their parent rate and their rate.
For these reason each clock is a composite clock and the operations they
use are different depending of the clock.
According to the datasheet it would be possible to select the parent
clock and the ratio, however currently the driver does not support it.

At the same time rename the driver from "twl6040-clk" to "twl6040-pdmclk".

This fix is along the same lines as 5e33ebff7e ("clk: imx7d: do not
set parent of ethernet time/ref clocks") and the explanation from that
commit is:
"The reason for the warning is that setting the parent enables the ENET
PLL since we are using CLK_OPS_PARENT_ENABLE. Enabling the ENET PLL can
cause clk_pllv3_wait_lock to sleep. See also:
commit fc8726a2c0 ("clk: core: support clocks which requires parents
enable (part 2)")."
imx7s-warp does not even use the FEC interface, so we should not really
configure the parent of IMX7D_ENET_AXI_ROOT_SRC in the common MX7 clock
driver code.
The dts file should use the assigned-clocks/assigned-clock-parents method,
so simply remove the configuration of IMX7D_ENET_AXI_ROOT_SRC parent.

It's always nice to see families reunited, and this is equally true when
talking about parent clocks and their children. However, if the orphan
clk had a positive prepare_count or enable_count, then we would not
migrate those counts up the parent chain correctly.
This has manifested with the recent critical clocks feature, which often
enables clocks very early, before their parents have been registered.
Fixed by replacing the call to clk_core_reparent with calls to
__clk_set_parent_{before,after}.

Merge tag 'xfs-rmap-for-linus-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
Pull more xfs updates from Dave Chinner:
"This is the second part of the XFS updates for this merge cycle, and
contains the new reverse block mapping feature for XFS.
Reverse mapping allows us to track the owner of a specific block on
disk precisely. It is implemented as a set of btrees (one per
allocation group) that track the owners of allocated extents.
Effectively it is a "used space tree" that is updated when we allocate
or free extents. i.e. it is coherent with the free space btrees we
already maintain and never overlaps with them.
This reverse mapping infrastructure is the building block of several
upcoming features - reflink, copy-on-write data, dedupe, online
metadata and data scrubbing, highly accurate bad sector/data loss
reporting to users, and significantly improved reconstruction of
damaged and corrupted filesystems. There's a lot of new stuff coming
along in the next couple of cycles,a nd it all builds in the rmap
infrastructure.
As such, it's a huge chunk of new code with new on-disk format
features and internal infrastructure. It warns at mount time as an
experimental feature and that it may eat data (as we do with all new
on-disk features until they stabilise). We have not released
userspace suport for it yet - userspace support currently requires
download from Darrick's xfsprogs repo and build from source, so the
access to this feature is really developer/tester only at this point.
Initial userspace support will be released at the same time kernel
with this code in it is released.
The new rmap enabled code regresses 3 xfstests - all are ENOSPC
related corner cases, one of which Darrick posted a fix for a few
hours ago. The other two are fixed by infrastructure that is part of
the upcoming reflink patchset. This new ENOSPC infrastructure
requires a on-disk format tweak required to keep mount times in
check - we need to keep an on-disk count of allocated rmapbt blocks so
we don't have to scan the entire btrees at mount time to count them.
This is currently being tested and will be part of the fixes sent in
the next week or two so users will not be exposed to this change"
