Here are a number of Staging and IIO driver fixes for 5.9-rc5.
The majority of these are IIO driver fixes, to resolve a timestamp issue
that was recently found to affect a bunch of IIO drivers.
The other fixes in here are:
- small IIO driver fixes
- greybus driver fix
- counter driver fix (came in through the IIO fixes tree)
All of these have been in linux-next for a while with no reported
issues.

On the older-gen 32-bit SoCs the meson-saradc driver is used to read the
SoC temperature. This requires reading calibration data from the eFuse.
Looking up the calibration data nvmem-cell requires the OF device_node
pointer to be available in the struct device which is passed to
devm_nvmem_cell_get(). This however got lost with commit 8cb631ccbb
("iio: Remove superfluous of_node assignments") from indio_dev->dev. As
devm_nvmem_cell_get() is called in the initialization phase the
device_node is not yet available because the NVMEM cell is looked up
before iio_device_register() is called (which would then set the
device_node automatically).
Use the parent device to look up the NVMEM cell instead to fix this
issue.

One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable structure in the iio_priv() data.
This data is allocated with kzalloc so no data can leak apart
from previous readings.
The explicit alignment of ts is necessary to ensure correct padding
on architectures where s64 is only 4 bytes aligned such as x86_32.

In case of CONFIG_PM is not set: __pm_runtime_suspend() returns -ENOSYS,

This change does the following:
* removes the SPI device table in favor of the OF device table
* adds 'name' && 'chip_id' fields to chip_info
* implements chip ID & silicon revision checking; the device ID for
AD7124-4 is 0x0, so just checking that value can be useless;
but at least the silicon revision isn't 0, so a non-zero value can be
used to check that "a" device is on the SPI bus; it's probably the best
way to narrow it down to one of the 2 AD7124 chip IDs

The SADC component in JZ47xx SoCs provides support for touchscreen
operations (pen position and pen down pressure) in single-ended and
differential modes.
The touchscreen component of SADC takes a significant time to stabilize
after first receiving the clock and a delay of 50ms has been empirically
proven to be a safe value before data sampling can begin.
Of the known hardware to use this controller, GCW Zero and Anbernic RG-350
utilize the touchscreen mode by having their joystick(s) attached to the
X/Y positive/negative input pins.
JZ4770 and later SoCs introduce a low-level command feature. With it, up
to 32 commands can be programmed, each one corresponding to a sampling
job. It allows to change the low-voltage reference, the high-voltage
reference, have them connected to VCC, GND, or one of the X-/X+ or Y-/Y+
pins.
This patch introduces support for 6 stream-capable channels:
- channel #0 samples X+/GND
- channel #1 samples Y+/GND
- channel #2 samples X-/GND
- channel #3 samples Y-/GND
- channel #4 samples X+/X-
- channel #5 samples Y+/Y-
Being able to sample X-/GND and Y-/GND is useful on some devices, where
one joystick is connected to the X+/Y+ pins, and a second joystick is
connected to the X-/Y- pins.
All the boards which probe this driver have the interrupt provided from
Device Tree, with no need to handle a case where the IRQ was not provided.

Merge 5.8-rc6 into staging-next
We need the staging fixes in here, and it resolves a merge issue with an
iio driver.

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

This change attaches the life-cycle of the kfifo buffer & IRQ to the
parent-device. This in turn cleans up the exit & error paths, since we
don't need to explicitly cleanup these resources.
The main intent here is to remove the explicit cleanup of the
'indio_dev->buffer' via 'iio_kfifo_free(indio_dev->buffer);'.
As we want to add support for multiple buffers per IIO device, having it
exposed like this makes it tricky to consider a safe backwards compatible
approach for it.

This change attaches the life-cycle of the channels array to the parent
device object that is attached to the IIO device.
This way we can remove from the cleanup code, the explicit
tiadc_channels_remove() which simply does a kfree() on the channels array.

Whilst it's unlikely this device will ever be instantiated using
ACPI, there is little advantage not assigning the of_device_id table in all
cases and it avoids providing an example that might be coppied into new
drivers.
Also include mod_devicetable.h whilst here as of_device_id is defined
in there so including the header is best practice.

These stop us using ACPI PRP0001 to instantiate the device.
I am slowly clearly out use of these in IIO to avoid this being coppied
into new drivers.
Here I also included mod_devicetable.h as we are using of_match_id
which is defined in there and hence it is best practice to include
it directly.

Dropping this allows use of ACPI PRP0001.
I'm also looking to drop all of_match_ptr use in IIO in order to avoid
it getting cut and paste into new drivers in the future.
Also add a direct include of mod_devicetable.h to reflect the use
of struct of_device_id.

Whilst this driver already supports explicit ACPI bindings we
might as well also allow for PRP0001 based binding.
I'm also keen to remove of_match_ptr from IIO drivers to avoid
this (now) anti-pattern getting coppied into new drivers.

Dropping of_match_ptr allows this driver to be used with ACPI.
The header includes are adjusted to include platform_device.h
and mod_devicetable.h instead of OF specific header as nothing
from that header itself is actually used.
