Change i2c_acpi_new_device() into i2c_acpi_new_device_by_fwnode() and
add a static inline wrapper providing the old i2c_acpi_new_device()
behavior.
This is necessary because in some cases we may only have access
to the fwnode / acpi_device and not to the matching physical-node
struct device *.

Enable drivers to tell ACPI that there's no need to power on a device for
probe. Drivers should still perform this by themselves if there's a need
to. In some cases powering on the device during probe is undesirable, and
this change enables a driver to choose what fits best for it.
Add a field called "flags" into struct i2c_driver for driver flags, and a
flag I2C_DRV_ACPI_WAIVE_D0_PROBE to tell a driver supports probe in ACPI D
states other than 0.

Here is the big set of IIO and staging driver patches for 5.14-rc1.
Loads of IIO driver updates and additions in here, the shortlog has the
full details.
For the staging side, we moved a few drivers out of staging, and deleted
the kpc2000 drivers as the original developer asked us to because no one
was working on them anymore.
Also in here are loads of coding style cleanups due to different intern
projects focusing on the staging tree to try to get experience doing

More and more drivers rely on devres to manage their resources, however
if bus' probe() and release() methods are not trivial and control some
of resources as well (for example enable or disable clocks, or attach
device to a power domain), we need to make sure that driver-allocated
resources are released immediately after driver's remove() method
returns, and not postponed until driver core gets around to releasing
resources. To fix that we open a new devres group before calling
driver's probe() and explicitly release it when we return from driver's
remove().

...
Multiple I2C bus drivers use similar bindings to obtain information needed
for I2C recovery. For example, for platforms using device-tree, the
properties look something like this:
&i2c {
...
pinctrl-names = "default", "gpio";
pinctrl-0 = <&pinctrl_i2c_default>;
pinctrl-1 = <&pinctrl_i2c_gpio>;
sda-gpios = <&pio 0 GPIO_ACTIVE_HIGH>;
scl-gpios = <&pio 1 (GPIO_ACTIVE_HIGH | GPIO_OPEN_DRAIN)>;
...
}
For this reason, we can add this common initialization in the core. This
way, other I2C bus drivers will be able to support GPIO recovery just by
providing a pointer to platform's pinctrl and calling i2c_recover_bus()
when SDA is stuck low.

There are few maximum bus frequencies being used in the I²C core code.
Provide generic definitions for bus frequencies and use them in the core.
The drivers may use predefined constants where it is appropriate.
Some of them are already using these under slightly different names.
We will convert them later to use newly introduced defines.
Note, the name of modes are chosen to follow well established naming
scheme [1].
These definitions will also help to avoid typos in the numbers that
may lead to subtle errors.
