Instead of requesting a new slot on the ring to the backend early, do
so only after all has been setup for the request to be sent. This
makes error handling easier as we don't need to undo the request id
allocation and ring slot allocation.

The mddev->flags are used for different purposes. There are a lot of
places we check/change the flags without masking unrelated flags, we
could check/change unrelated flags. These usage are most for superblock
write, so spearate superblock related flags. This should make the code
clearer and also fix real bugs.

In some configurations, gcc cannot trace the state of variables
across a spin_unlock() barrier, leading to a warning about
correct code:
xgene_enet_main.c: In function 'xgene_enet_start_xmit':
../../../phy/mdio-xgene.h:112:14: error: 'mss_index' may be used uninitialized in this function [-Werror=maybe-uninitialized]
Here we can trivially move the assignment before that spin_unlock,
which reliably avoids the warning.

The array for initializing the cle is set up on the stack with
almost entirely constant data and then passed to a function that
converts it into HW specific bit patterns. With the latest
addition, the size of this array has grown to the point that
we get a warning about potential stack overflow in allmodconfig
builds:
xgene_enet_cle.c: In function ‘xgene_enet_cle_init’:
xgene_enet_cle.c:836:1: error: the frame size of 1032 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
Looking a bit deeper at the usage, I noticed that the only modification
of the data is in dead code, as we don't even use the cle module
for phy_mode other than PHY_INTERFACE_MODE_XGMII. This means we
can simply mark the structure constant and access it directly rather
than passing the pointer down through another structure, making
the code more efficient at the same time as avoiding the
warning.

Some driver is using this type of DT bindings for clock (more detail,
see ${LINUX}/Documentation/devicetree/bindings/sound/simple-card.txt).
sound_soc {
...
cpu {
clocks = <&xxx>;
...
};
codec {
clocks = <&xxx>;
...
};
};
Current driver in this case uses of_clk_get() for each node, but there
is no devm_of_clk_get() today.
OTOH, the problem of having devm_of_clk_get() is that it encourages the
use of of_clk_get() when clk_get() is more desirable.
Thus, this patch adds new devm_get_clk_from_chile() which explicitly
reads as get a clock from a child node of this device.
By this function, we can also use this type of DT bindings
sound_soc {
clocks = <&xxx>, <&xxx>;
clock-names = "cpu", "codec";
clock-ranges;
...
cpu {
...
};
codec {
...
};
};

The broadcom clk driver Kconfig file selects and depends on the
COMMON_CLK_IPROC config for different SoC specific drivers. Let's
simplify this by always selecting the COMMON_CLK_IPROC config,
turning it into a set of library code. We still want to retain
the SoC specific options, so we leave those in place. Since we're
here we also drop COMMON_CLK dependency because that's implicitly
handled by including this file in drivers/clk/Kconfig in the
right place and also make CLK_BCM_KONA default to y on the
architecture it exists for instead of plain default y.

Some peripheral clocks, like the VEC (Video EnCoder) clock need to be set
to a precise rate (in our case 108MHz). With the current implementation,
where peripheral clocks are not allowed to forward rate change requests
to their parents, it is impossible to match this requirement unless the
bootloader has configured things correctly, or a specific rate has been
assigned through the DT (with the assigned-clk-rates property).
Add a new field to struct bcm2835_clock_data to specify which parent
clocks accept rate change propagation, and support set rate propagation
in bcm2835_clock_determine_rate().
