Allow mlxreg-io platform driver activation for the next generation
systems, in particular for MQM87xx, MSN34xx, MSN37xx types, which have:
- extended reset causes bits related to ComEx reset, voltage devices
firmware upgrade, system platform reset;
- additional CPLD device;
- JTAG select capability;

Exchange LED configuration between msn201x and next generation systems
types.
Bug was introduced when LED driver activation was added to mlx-platform.
LED configuration for the three new system MQMB7, MSN37, MSN34 was
assigned to MSN21 and vice versa. This bug affects MSN21 only and
likely requires backport to v4.19.

Shift by one the registers for tachometers (7 - 12).
This fix is relevant for the same new systems MQMB7, MSN37, MSN34,
which are about to be released to the customers.
At the moment, none of them is at customers sites. The customers will
not suffer from this change.
This fix is necessary, because register used before for tachometer 7
has been than reserved for the second PWM for newer systems, which are
not supported yet in mlx-platform driver. So registers of tachometers
7-12 have been shifted by one.

We lose even config space access when we power gate the ISP
via the PUNIT. That makes lspci & co. produce gibberish.
To fix that let's try to implement actual runtime pm hooks
and inform the pci core that the device always goes to
D3cold. That will cause the pci core to resume the device
before attempting config space access.
This introduces another annoyance though. We get the
following error every time we try to resume the device:
intel_atomisp2_pm 0000:00:03.0: Refused to change power state, currently in D3
The reason being that the pci core tries to put the device
back into D0 via the standard PCI PM mechanism before
calling the driver resume hook. To fix this properly
we'd need to infiltrate the platform pm hooks (could
turn ugly real fast), or use pm domains (which don't
seem to exist on x86), or some extra early resume
hook for the driver (which doesn't exist either).
So maybe we just choose to live with the error?

According to Asus firmware engineers, the meaning of these codes is only
to notify the OS that the screen brightness has been turned on/off by
the EC. This does not match the meaning of KEY_DISPLAYTOGGLE /
KEY_DISPLAY_OFF, where userspace is expected to change the display
brightness.

When the OS registers to handle events from the display off hotkey the
EC will send a notification with 0x35 for every key press, independent
of the backlight state.
The behavior of this key on Windows, with the ATKACPI driver from Asus
installed, is turning off the backlight of all connected displays with a
fading effect, and any cursor input or key press turning the backlight
back on. The key press or cursor input that wakes up the display is also
passed through to the application under the cursor or under focus.
The key that matches this behavior the closest is KEY_SCREENLOCK.

In the past, Asus firmwares would change the panel backlight directly
through the EC when the display off hotkey (Fn+F7) was pressed, and
only notify the OS of such change, with 0x33 when the LCD was ON and
0x34 when the LCD was OFF. These are currently mapped to
KEY_DISPLAYTOGGLE and KEY_DISPLAY_OFF, respectively.
Most recently the EC on Asus most machines lost ability to toggle the
LCD backlight directly, but unless the OS informs the firmware it is
going to handle the display toggle hotkey events, the firmware still
tries change the brightness through the EC, to no effect. The end result
is a long list (at Endless we counted 11) of Asus laptop models where
the display toggle hotkey does not perform any action. Our firmware
engineers contacts at Asus were surprised that there were still machines
out there with the old behavior.
Calling WMNB(ASUS_WMI_DEVID_BACKLIGHT==0x00050011, 2) on the _WDG device
tells the firmware that it should let the OS handle the display toggle
event, in which case it will simply notify the OS of a key press with
0x35, as shown by the DSDT excerpts bellow.

Pull x86 platform driver updates from Darren Hart:
- Move the Dell dcdbas and dell_rbu drivers into platform/drivers/x86
as they are closely coupled with other drivers in this location.
- Improve _init* usage for acerhdf and fix some usage issues with
messages and module parameters.
- Simplify asus-wmi by calling ACPI/WMI methods directly, eliminating
workqueue overhead, eliminate double reporting of keyboard backlight.
- Fix wake from USB failure on Bay Trail devices (intel_int0002_vgpio).
- Notify intel_telemetry users when IPC1 device is not enabled.
- Update various drivers with new laptop model IDs.

Export asus_wmi_evaluate_method() and related headers for use by other
drivers.
hid-asus is going to use this to avoid advertising that it has a keyboard
backlight when the keyboard backlight is controlled via WMI.

Since commit dbb3d78f61ba ("platform/x86: asus-wmi: Call led hw_changed
API on kbd brightness change"), asus-wmi directly changes the keyboard
LED brightness when the keyboard brightness keys are pressed,
raising the appropriate notification.
However, this notification was unintentionally also being raised during
boot and resume from suspend. This was resulting in userspace showing
the keyboard LED OSD on resume for no good reason.
Move the keyboard LED brightness changed notification
from kbd_led_update to the new kbd_led_set_by_kbd function which is only
called from the keyboard brightness function keys codepath.

The only usage of device_type structure is getting stored as
a reference in the type field of device structure. This type
field is declared const. Therefore, the device_type structure
can never be modified and can be declared as const.

The Image Signal Processor found on Cherry Trail devices is brought up in
D0 state on devices which have camera sensors attached to it. The ISP will
not enter D3 state again without some massaging of its registers beforehand
and the ISP not being in D3 state blocks the SoC from entering S0ix modes.
There was a driver for the ISP in drivers/staging but that got removed
again because it never worked. It does not seem likely that a real
driver for the ISP will be added to the mainline kernel anytime soon.
This commit adds a dummy driver which contains the necessary magic from
the staging driver to powerdown the ISP, so that Cherry Trail devices where
the ISP is used will properly use S0ix modes when suspended.
Together with other recent S0ix related fixes this allows S0ix modes to
be entered on e.g. a Chuwi Hi8 Pro and a HP x2 210.

Add min-x and min-y settings now that we've support for this and for some
models also update the width/height settings with slighly more accurate
values.
This fixes touches along the edges registering at the wrong coordinates.
While at it also set max-fingers to 10 in a couple of cases where the
touchpad can handle 10 fingers (rather then the default 5) and that was
missing.

On some Goldmont based systems such as ASRock J3455M the BIOS may not
enable the IPC1 device that provides access to the PMC and PUNIT. In
such scenarios, the IOSS and PSS resources from the platform device can
not be obtained and result in a invalid telemetry_plt_config which is an
internal data structure that holds platform config and is maintained by
the telemetry platform driver.
This is also applicable to the platforms where the BIOS supports IPC1
device under debug configurations but IPC1 is disabled by user or the
policy.
This change allows user to know the reason for not seeing entries under
/sys/kernel/debug/telemetry/* when there is no apparent failure at boot.

The original asus-wmi queues a work which calls the ACPI/WMI methods to
update the keyboard LED brightness. Similar drivers - acer-wmi,
dell-wmi-led just call the ACPI/WMI methods directly without workqueues.
This patch simplifies the keyboard brightness updating process which
calls the kbd_led_update function directly without workqueue in
asus-wmi.
