- Add support for a new Goodix HID over SPI driver (Charles Wang)
Note: this driver doesn't rely on the spefication of HID over SPI
provided by Microsoft, thus needs a separate driver, not a generic bus
transport low level driver.
Various Wacom fixes (Jason Gerecke):
- Support for high-resolution wheel scrolling
- Support touchrings with relative motion
- Support devices with two touchrings
- Support sequence numbers smaller than 16-bit
Add reg-name: "dbi2", "atu" for i.MX8M PCIe Endpoint.
For i.MX8M PCIe EP, the dbi2 and atu addresses are pre-defined in the
driver. This method is not good.
In commit b7d67c6130 ("PCI: imx6: Add iMX95 Endpoint (EP) support"),
Frank suggests to fetch the dbi2 and atu from DT directly. This commit is
preparation to do that for i.MX8M PCIe EP.
These changes wouldn't break driver function. When "dbi2" and "atu"
properties are present, i.MX PCIe driver would fetch the according base
addresses from DT directly. If only two reg properties are provided, i.MX
PCIe driver would fall back to the old method.

Commit 9094e53ff5 ("pmdomain: core: Use dev_name() instead of
kobject_get_path() in debugfs") severely shortened the names of devices
in a PM Domain. Now the most common format[1] consists of a 32-bit
unit-address (8 characters), followed by a dot and a node name (20
characters for "air-pollution-sensor" and "interrupt-controller", which
are the longest generic node names documented in the Devicetree
Specification), for a typical maximum of 29 characters.
This offers a good opportunity to reduce the table width of the debug
summary:
- Reduce the device name field width from 50 to 30 characters, which
matches the PM Domain name width,
- Reduce the large inter-column space between the "performance" and
"managed by" columns.
Visual impact:
- The "performance" column now starts at a position that is a
multiple of 16, just like the "status" and "children" columns,
- All of the "/device", "runtime status", and "managed by" columns are
now indented 4 characters more than the columns right above them,
- Everything fits in (one less than) 80 characters again ;-)
[1] Note that some device names (e.g. TI AM335x interconnect target
modules) do not follow this convention, and may be much longer, but
these didn't fit in the old 50-character column width either.

The removed code was added to handle the case where the power domain is
already on during the driver's probing. In this use case, the "is_off"
parameter is passed as false to pm_genpd_init() to inform it not to call
the power_on() callback, as it's unnecessary to perform the hardware
power-on procedure since the power domain is already on. Therefore, with
the call to clk_bulk_prepare_enable() by probe(), the system is in the
same operational state as when "is_off" is passed as true after the
power_on() callback execution:
probe() -> is_off == true -> clk_bulk_prepare_enable() called by power_on()
probe() -> is_off == false -> clk_bulk_prepare_enable() called by probe()
Reaching the same logical and operational state, it follows that upon
driver removal, there is no need to perform different actions depending
on the power domain's on/off state during probing.

When entering the "len & sizeof(u32)" branch, len must be less than 8.
So after one operation, len must be less than 4.
At this time, "len -= sizeof(u32)" is not necessary for 64-bit CPUs.
After that, replace `while' loops with equivalent `for' to make the
code structure a little bit better by the way.

The qcom-rng driver supports both ACPI and device tree-based systems.
ACPI support was broken when the hw_random interface support was added.
Let's go ahead and fix this by adding the appropriate driver data to the
ACPI match table, and change the of_device_get_match_data() call to
device_get_match_data() so that it will also work on ACPI-based systems.
This fix was boot tested on a Qualcomm Amberwing server (ACPI based) and
on a Qualcomm SA8775p Automotive Development Board (DT based). I also
verified that qcom-rng shows up in /proc/crypto on both systems.
