gpio: syscon: rockchip: add GRF GPIO support for rk3328
In Rockchip RK3328, the output only GPIO_MUTE pin, originally for codec
mute control, can also be used for general purpose. It is manipulated by
the GRF_SOC_CON10 register in GRF. Aside from the GPIO_MUTE pin, the HDMI

Currently this GRF GPIO controller only supports the mute pin. If needed
in the future, the HDMI pins support can also be added.

gpio: aspeed: Add interfaces for co-processor to grab GPIOs
On the Aspeed chip, the GPIOs can be under control of the ARM
chip or of the ColdFire coprocessor. (There's a third command
source, the LPC bus, which we don't use or support yet).
The control of which master is allowed to modify a given
GPIO is per-bank (8 GPIOs).
Unfortunately, systems already exist for which we want to
use GPIOs of both sources in the same bank.
This provides an API exported by the gpio-aspeed driver
that an aspeed coprocessor driver can use to "grab" some
GPIOs for use by the coprocessor, and allow the coprocessor
driver to provide callbacks for arbitrating access.
Once at least one GPIO of a given bank has been "grabbed"
by the coprocessor, the entire bank is marked as being
under coprocessor control. It's command source is switched
to the coprocessor.
If the ARM then tries to write to a GPIO in such a marked bank,
the provided callbacks are used to request access from the
coprocessor driver, which is responsible to doing whatever
is necessary to "pause" the coprocessor or prevent it from
trying to use the GPIOs while the ARM is doing its accesses.
During that time, the command source for the bank is temporarily
switched back to the ARM.

gpio: aspeed: Add "Read Data" register to read the write latch
The Aspeed GPIO hardware has a quirk: the value register, for an
output GPIO, doesn't contain the last value written (the write
latch content) but the sampled input value.
This means that when reading back shortly after writing, you can
get an incorrect value as the input value is delayed by a few
synchronizers.
The HW supports a separate read-only register "Data Read Register"
which allows you to read the write latch instead.
This adds the definition for it, and uses it for the initial
population of the GPIO value cache. It will be used more in
subsequent patches.

gpio: Add API to explicitly name a consumer
The GPIO (descriptor) API registers a "label" naming what is
currently using the GPIO line. Typically this is taken from
things like the device tree node, so "reset-gpios" will result
in he line being labeled "reset".
The technical effect is pretty much zero: the use is for
debug and introspection, such as "lsgpio" and debugfs files.
However sometimes the user want this cuddly feeling of
listing all GPIO lines and seeing exactly what they are for
and it gives a very fulfilling sense of control. Especially
in the cases when the device tree node doesn't provide a
good name, or anonymous GPIO lines assigned just to
"gpios" in the device tree because the usage is implicit.
For these cases it may be nice to be able to label the
line directly and explicitly.

defined performance counters.
- support for sparse and cleanups suggested by it.
- support for R_RISCV_32 (a relocation, not the 32-bit ISA).
- some MAINTAINERS cleanups.
- the addition of CONFIG_HVC_RISCV_SBI to our defconfig, as it's
always present.
I've given these a simple build+boot test"

"Mostly the PPC part of the release, but also switching to Arnd's fix
for the hyperv config issue and a typo fix.
Main PPC changes:
- reimplement the MMIO instruction emulation

The specified locations are not right. Fix the wildcard logic
to point to the correct directories.

kernel-parameters.txt: fix pointers to sound parameters
The alsa parameters file was renamed to alsa-configuration.rst.
With regards to OSS, it got retired as a hole by at changeset 727dede0ba8a ("sound: Retire OSS"). So, it doesn't make sense
to keep mentioning it at kernel-parameters.txt.
Some files, like tools/memory-model/README has references to
a Documentation file that is locale to it. Handle references
that are relative to them too.
