Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers while registering clks in
these drivers, allowing us to move closer to a clear split of
consumer and provider clk APIs.

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 0861e5b8cf80 (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.

The driver is to provide the functional clock to OMAP4/5 McPDM. The clock
is named as pdmclk in the documentations so change the function names,
structure names and variables to align with this.
At the same time rename the driver from "twl6040-clk" to "twl6040-pdmclk".
This can be done w/o regression since the clock driver is not in use at
the moment, the MFD core driver is not even registering the device for it.

This fix is along the same lines as 5e33ebff7edd ("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 fc8726a2c021 ("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}.

According to the datasheet, SDn clocks are from the SDSRC clock. And
the SDSRC has a 1/2 divider. So, we should have ".sdsrc" as an internal
core clock. Otherwise, since the sdhi driver will calculate clock for
a sd card using the wrong parent clock rate, and then performance will
be not good.

The condition passed to read*_poll_timeout() is the break condition,
i.e. wait for this condition to happen and return success.
The original code assumed the opposite, resulting in a warning when
the PLL clock rate was changed but never lost it's lock as far as
the readout indicated. This was verified by checking the read out
register value.

Since commit 63a4cc24867d, bio->bi_rw contains flags in the lower
portion and the op code in the higher portions. This means that
old code that relies on manually setting bi_rw is most likely
going to be broken. Instead of letting that brokeness linger,
rename the member, to force old and out-of-tree code to break
at compile time instead of at runtime.

Commit abf545484d31 changed it from an 'rw' flags type to the
newer ops based interface, but now we're effectively leaking
some bdev internals to the rest of the kernel. Since we only
care about whether it's a read or a write at that level, just
pass in a bool 'is_write' parameter instead.
Then we can also move op_is_write() and friends back under
CONFIG_BLOCK protection.

Pull pwm updates from Thierry Reding:
"This set of changes improve some aspects of the atomic API as well as
make use of this new API in the regulator framework to allow properly
dealing with critical regulators controlled by a PWM.
Aside from that there's a bunch of updates and cleanups for existing
drivers, as well as the addition of new drivers for the Broadcom
iProc, STMPE and ChromeOS EC controllers"
