Pull x86 cpu-feature updates from Ingo Molnar:
- Rework the Intel model names symbols/macros, which were decades of
ad-hoc extensions and added random noise. It's now a coherent, easy
to follow nomenclature.
- Add new Intel CPU model IDs:
- "Tiger Lake" desktop and mobile models
- "Elkhart Lake" model ID
- and the "Lightning Mountain" variant of Airmont, plus support code
- Add the new AVX512_VP2INTERSECT instruction to cpufeatures
- Remove Intel MPX user-visible APIs and the self-tests, because the
toolchain (gcc) is not supporting it going forward. This is the
first, lowest-risk phase of MPX removal.
- Remove X86_FEATURE_MFENCE_RDTSC
- Various smaller cleanups and fixes

Pull GPIO updates from Linus Walleij:
"This is the bulk of changes in the GPIO subsystem for the v5.4 kernel
cycle.
Core changes:
- Support hierarchical GPIO irqchips.
We now have three consumers that can use this: Intel IXP4xx,
ThunderX and Qualcomm SPMI GPIO (in the pinctrl subsystem).
The support code has been long in the making and hashed out so it
should be easily adaptable for all hierarchical irqchip parents.
The code only gets compiled in if hierarchical irqchip is used at
the topmost irq controller at least, as the hierarchical irqchip
requires strict hierarchy all the way up in the system.
- Determine the need for a "valid_mask" for GPIO lines on the
gpio_chip and conversely for the "valid_mask" for the GPIO
interrupt chip interrupt lines by looking for a .init_valid_mask()
callback in the main chip or GPIO interrupt chip respectively.
Allocate it with bitmap_alloc().
- Isolate the device tree/open firmware GPIO description code out in
its own file properly.
- Isolate the ACPI GPIO description code out in its own file
properly.
- Drop a whole lot of #ifdef:s in the main includes: it does not hurt
to keep the include items around, and we get quicker and clearer
compile failures if the appropriate kernel symbols are not selected
for drivers.
New/deleted drivers:
- New driver for Aspeed SGPIO.
- The KS8695 driver is deleted as the platform gets deleted from
arch/arm in this kernel cycle.
- The Cirrus Logic Madera driver now supports CS47L92 and CS47L15.
- The Freescale MPC8xxx now supports LS1028A and LS1088A.
Driver improvements:
- We pass the GPIO irqchip intialization by directly filling in the
struct instead of using set-up functions (the new way) for Intel
MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed, ZX, VF610, TQMX86,
MT7621, Zynq and EP93xx.
Out-of-band changes:
- Fix a GPIO header inclusion in Unicore - no response from
maintainer.
- Drop FMC subsystem from MAINTAINERS - was deleted in the GPIO tree
last cycle so let's mop up the shards"

When driver has been switched to use ACPI battery API in the commit
7973353e92ee ("Refactor charge threshold to use the battery hooking API")
it makes it implicitly dependent to a corresponding kernel configuration

Allow to poll on the cros_ec device to receive the MKBP events.
The /dev/cros_[ec|fp|..] file operations now implements the poll
operation. The userspace can now receive specific MKBP events by doing
the following:
- Open the /dev/cros_XX file.
- Call the CROS_EC_DEV_IOCEVENTMASK ioctl with the bitmap of the MKBP
events it wishes to receive as argument.
- Poll on the file descriptor.
- When it gets POLLIN, do a read on the file descriptor, the first
queued event will be returned (using the struct
ec_response_get_next_event format: one byte of event type, then
the payload).
The read() operation returns at most one event even if there are several
queued, and it might be truncated if the buffer is smaller than the
event (but the caller should know the maximum size of the events it is
reading).
read() used to return the EC version string, it still does it when no
event mask or an empty event is set for backward compatibility (despite
nobody really using this feature).
This will be used, for example, by the userspace daemon to receive and
treat the EC_MKBP_EVENT_FINGERPRINT sent by the FP MCU.

Since the rpmsg_endpoint is created before probe is called, it's
possible that a host event is received during cros_ec_register, and
there would be some pending work in the host_event_work workqueue while
cros_ec_register is called.
If cros_ec_register fails, when the leftover work in host_event_work
run, the ec_dev from the drvdata of the rpdev could be already set to
NULL, causing kernel crash when trying to run cros_ec_get_next_event.
Fix this by creating the rpmsg_endpoint by ourself, and when
cros_ec_register fails (or on remove), destroy the endpoint first (to
make sure there's no more new calls to cros_ec_rpmsg_callback), and then
cancel all works in the host_event_work workqueue.

After changing the valid_mask for the struct gpio_chip
to detect the need and presence of a valid mask with the
presence of a .init_valid_mask() callback to fill it in,
we augment the gpio_irq_chip to use the same logic.
Switch all driver using the gpio_irq_chio valid_mask
over to this new method.
This makes sure the valid_mask for the gpio_irq_chip gets
filled in when we add the gpio_chip, which makes it a
little easier to switch over drivers using the old
way of setting up gpio_irq_chip over to the new method
of passing the gpio_irq_chip along with the gpio_chip.
(See drivers/gpio/TODO for details.)

Commit 871f1f2bcb01 ("platform/x86: intel_int0002_vgpio: Only implement
irq_set_wake on Bay Trail") removed the irq_set_wake method from the
struct irq_chip used on Cherry Trail, but it did not set
IRQCHIP_SKIP_SET_WAKE causing kernel/irq/manage.c: set_irq_wake_real()
to return -ENXIO.
This causes the kernel to no longer see PME events reported through the
INT0002 device as wakeup events. Which e.g. breaks wakeup by the (USB)
keyboard on many Cherry Trail 2-in-1 devices.

On a Xen-based PVH virtual machine with more than 4 GiB of RAM,
intel_pmc_core fails initialization with the following warning message
from the kernel, indicating that the driver is attempting to ioremap
RAM:
ioremap on RAM at 0x00000000fe000000 - 0x00000000fe001fff

Call Trace:
? pmc_core_probe+0x87/0x2d0 [intel_pmc_core]

This issue appears to manifest itself because of the following fallback
mechanism in the driver:
if (lpit_read_residency_count_address(&slp_s0_addr))
pmcdev->base_addr = PMC_BASE_ADDR_DEFAULT;
The validity of address PMC_BASE_ADDR_DEFAULT (i.e., 0xFE000000) is not
verified by the driver, which is what this patch introduces. With this
patch, if address PMC_BASE_ADDR_DEFAULT is in RAM, then the driver will
not attempt to ioremap the aforementioned address.

There is a bit of mess between cros-ec mfd includes and platform
includes. For example, we have a linux/mfd/cros_ec.h include that
exports the interface implemented in platform/chrome/cros_ec_proto.c. Or
we have a linux/mfd/cros_ec_commands.h file that is non related to the
multifunction device (in the sense that is not exporting any function of
the mfd device). This causes crossed includes between mfd and
platform/chrome subsystems and makes the code difficult to read, apart
from creating 'curious' situations where a platform/chrome driver includes
a linux/mfd/cros_ec.h file just to get the exported functions that are
implemented in another platform/chrome driver.
In order to have a better separation on what the cros-ec multifunction
driver does and what the cros-ec core provides move and rework the
affected includes doing:
- Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h
- Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c
driver from include/linux/mfd/cros_ec.h to a new file
include/linux/platform_data/cros_ec_proto.h
- Update all the drivers with the new includes, so
- Drivers that only need to know about the protocol include
- linux/platform_data/cros_ec_proto.h
- linux/platform_data/cros_ec_commands.h
- Drivers that need to know about the cros-ec mfd device also include
- linux/mfd/cros_ec.h

That's a driver to talk with the ChromeOS Embedded Controller via a
miscellaneous character device, it creates an entry in /dev for every
instance and implements basic file operations for communicating with the
Embedded Controller with an userspace application. The API is moved to
the uapi folder, which is supposed to contain the user space API of the
kernel.
Note that this will replace current character device interface
implemented in the cros-ec-dev driver in the MFD subsystem. The idea is
to move all the functionality that extends the bounds of what MFD was
designed to platform/chrome subsystem.

An MFD is a device that contains several sub-devices (cells). For instance,
the ChromeOS EC fits in this description as usually contains a charger and
can have other devices with different functions like a Real-Time Clock,
an Audio codec, a Real-Time Clock, ...
If you look at the driver, though, we're doing something odd. We have
two MFD cros-ec drivers where one of them (cros-ec-core) instantiates
another MFD driver as sub-driver (cros-ec-dev), and the latest
instantiates the different sub-devices (Real-Time Clock, Audio codec,
etc).

|___ mfd-cellA (cros-ec-dev)

| |__ mfd-cell1
| |__ ...
|
|___ mfd-cellB (cros-ec-dev)
|__ mfd-cell0
|__ mfd-cell1

The problem that was trying to solve is to describe some kind of topology for
the case where we have an EC (cros-ec) chained with another EC
(cros-pd). Apart from that this extends the bounds of what MFD was
designed to do we might be interested on have other kinds of topology that
can't be implemented in that way.
Let's prepare the code to move the cros-ec-core part from MFD to
platform/chrome as this is clearly a platform specific thing non-related
to a MFD device.

Add the GET_BATT_PPID_INFO=0x8A command to the allowlist of accepted
telemetry commands. In addition, since this new command requires
verifying the contents of some of the arguments, I also restructure
the request to use a union of the argument structs. Also, zero out the
request buffer before each request, and change "whitelist" to
"allowlist".

Commit 10a08fd65ec1 ("ACPI: PM: Set up EC GPE for system wakeup from
drivers that need it") assumed that the EC GPE would only need to be
set up for system wakeup if either the intel-hid or the intel-vbtn
driver was in use, but that turns out to be incorrect. In particular,
on ASUS Zenbook UX430UNR/i7-8550U, if the EC GPE is not enabled while
suspended, the system cannot be woken up by opening the lid or
pressing a key, and that machine doesn't use any of the drivers
mentioned above.
For this reason, always set up the EC GPE for system wakeup from
suspend-to-idle by setting and clearing its wake mask in the ACPI
suspend-to-idle callbacks.

We have extra indentation level where it can be avoided by changing conditional

Do it here for three such locations in the driver.

The use of sscanf() is an overkill here. Moreover, there is no need to check
for count to be 0, since it's guaranteed by sysfs not to be.
Taking above into account, replace sscanf() with kstrtoint() calls.

There are few issues with the current code:
- the error code from kstrtouint() is shadowed
- the error code from asus_wmi_set_devstate() is ignored
- the extra check against 0 for count (this is guaranteed by sysfs)
Fix these issues by doing a slight refactoring of charge_threshold_store().

Notice that intel_button_array_enable() never disables the power
button which is the only one needed to wake up the system from
suspend-to-idle, so it can be safely called during suspend-to-idle
as well as during "regular" system suspend, and rearrange the
code in the driver's "suspend" and "resume" callbacks accordingly.
While at it, use pm_suspend_no_platform() to check if the current
suspend-resume cycle is suspend-to-idle, as that is the only
case when the device should be enabled while suspended.

Both intel-hid and intel-vbtn set a wakeup_mode flag causing them
to behave in a special way during system suspend and while suspended
in their "prepare" PM callbacks and clear it in their "resume" PM
callbacks. That may cause the wakeup_mode flag to remain set after
a system suspend failure (if some other driver's "suspend" callback
returns an error before the "suspend" callback of either intel-hid
or intel-vbtn is invoked).
After commit 10a08fd65ec1 ("ACPI: PM: Set up EC GPE for system wakeup
from drivers that need it") that also affects the "wakeup mask" bit
of the EC GPE, which may not be cleared after a failing system
suspend.
Fix this issue by adding "complete" PM callbacks to intel-hid and
intel-vbtn to clear the wakeup_mode flag and the "wakeup mask" bit
of the EC GPE if they have not been cleared earlier.

Platform drivers now have the option to have the platform core create
and remove any needed sysfs attribute files. So take advantage of that
and do not register "by hand" a bunch of sysfs files.
