There are no in-tree users of this driver, so nothing defines

Add a dependency on GPIOLIB_LEGACY for the moment to avoid the build
failure, and make sure the sound driver does not get built without the
mfd portion either pass that dependency along.
Alternatively, we could remove the mfd driver along with the radio and
sound portions.

dt-bindings: mfd: Move embedded controllers to own directory
Move several embedded controller bindings (like ChromeOS EC, Gateworks
System Controller and Kontron sl28cpld Board Management) to new
subdirectory "embedded-controller" matching their purpose.
An embedded controller (EC) is a discrete component that contains a
microcontroller (i.e. a small CPU running a small firmware without
operating system) mounted into a larger computer system running
a fully fledged operating system that needs to utilize the embedded
controller as part of its operation.
So far the EC bindings were split between "mfd" and "platform"
directory. MFD name comes from Linux, not hardware, and "platform" is a
bit too generic.
Rename Gateworks GSC and Huawei Gaokun filenames to match compatible, as
preferred for bindings.

mfd: da9063: Split chip variant reading in two bus transactions
We observed the initial probe of the da9063 failing in
da9063_get_device_type in about 30% of boots on a Xilinx ZynqMP based
board. The problem originates in da9063_i2c_blockreg_read, which uses
a single bus transaction to turn the register page and then read a
register. On the bus, this should translate to a write to register 0,
followed by a read to the target register, separated by a repeated
start. However, we found that after the write to register 0, the
controller sometimes continues directly with the register address of
the read request, without sending the chip address or a repeated start
in between, which makes the read request invalid.
To fix this, separate turning the page and reading the register into
two separate transactions. This brings the initialization code in line
with the rest of the driver, which uses register maps (which to my
knowledge do not use repeated starts after turning the page). This has
been included in our kernel for several months and was recently
included in a shipped product. For us, it reliably fixes the issue,
and we have not observed any new issues.
While the underlying problem is probably with the i2c controller or
its driver, I still propose a change here in the interest of
robustness: First, I'm not sure this issue can be fixed on the
controller side, since there are other issues related to repeated
start which can't (AR# 60695, AR# 61664). Second, similar problems
might exist with other controllers.

Pull smb server fixes from Steve French:
- Fix limiting repeated connections from same IP
- Fix for extracting shortname when name begins with a dot
- Four smbdirect fixes:
- three fixes to the receive path: potential unmap bug, potential
resource leaks and stale connections, and also potential use
after free race
- cleanup to remove unneeded queue

tools/power turbostat: Fix bogus SysWatt for forked program
Similar to delta_cpu(), delta_platform() is called in turbostat main
loop. This ensures accurate SysWatt readings in periodic monitoring mode
$ sudo turbostat -S -q --show power -i 1
CoreTmp PkgTmp PkgWatt CorWatt GFXWatt RAMWatt PKG_% RAM_% SysWatt

58 60 6.27 1.11 0.24 0.00 0.00 0.00 13.55
However, delta_platform() is missing for forked program and causes bogus
SysWatt reporting,
