Colibri modules need to be powered using the power pins 3V3 and
AVDD_AUDIO. Add fixed regulators which represent this power rails.
Potentially, those power rails could be switched on a carrier
board. A carrier board device tree could add a own regulator with
a GPIO, and reference that regulator in a vin-supply property of
those new module level system regulators. This also synchronize
the name of the +3.3V regulator with the one used in the Colibri
VF50/VF61 device tree.

Only i.MX 7Dual SoC supports CPU frequencies of up to 1GHz. The i.MX
7Solo can run with up to 800MHz and does so without making use of DVFS
usually. While the device tree clearly specified a too fast operating
point for i.MX 7Solo, the kernel did not used it in practise so far
because the CPUfreq driver does not get loaded on i.MX 7Solo devices
(since the fsl,imx7s compatible string is not in the list of devices
making use of the cpufreq-dt driver...).

bc677ff42e adds a device-tree property
to specify that an external watchdog reset is used to reset other
portions of the board and not just the IMX6 SoC.
This adds the property to the proper watchdog as well as the pinmux for
the Gateworks Ventana boards that use this external watchdog reset to
reset the PMIC which will reset all the PMIC power rails and not just
a chip-level IMX6 reset. This helps to work around various system issues
that can cause a hang when coming out of reset.

"As mentioned in the pull the other day, a few more fixes for this
round, all related to the bio op changes in this series.
Two fixes, and then a cleanup, renaming bio->bi_rw to bio->bi_opf. I
wanted to do that change right after or right before -rc1, so that
risk of conflict was reduced. I just rebased the series on top of
current master, and no new ->bi_rw usage has snuck in"

"This tree was waiting on some media stuff I hadn't had time to get a

It's been around a bit on the list and shouldn't affect anything
outside adding the generic API and moving some ARM drivers to using
it"

Since commit 63a4cc2486, 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.
No intended functional changes in this commit.

Commit abf545484d 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.

"This update is to allow architecture emulation containers to function
such that the emulation binary can be housed outside the container
itself. The container and fs parts both have acks from relevant
experts.
To use the new feature you have to add an F option to your binfmt_misc
configuration"
From the docs:
"The usual behaviour of binfmt_misc is to spawn the binary lazily when
the misc format file is invoked. However, this doesn't work very well
in the face of mount namespaces and changeroots, so the F mode opens
the binary as soon as the emulation is installed and uses the opened
image to spawn the emulator, meaning it is always available once
installed, regardless of how the environment changes"
* tag 'binfmt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/binfmt_misc:
