Jonathan Yong 9745fb0747 platform/x86/intel: Add Primary to Sideband (P2SB) bridge support
SoC features such as GPIO are accessed via a reserved MMIO area,
we don't know its address but can obtain it from the BAR of
the P2SB device, that device is normally hidden so we have to
temporarily unhide it, read address and hide it back.

There are already a few users and at least one more is coming which
require an access to Primary to Sideband (P2SB) bridge in order
to get IO or MMIO BAR hidden by BIOS.

Create a library to access P2SB for x86 devices in a unified way.

Background information
======================
Note, the term "bridge" is used in the documentation and it has nothing
to do with a PCI (host) bridge as per the PCI specifications.

The P2SB is an interesting device by its nature and hardware design.
First of all, it has several devices in the hardware behind it. These
devices may or may not be represented as ACPI devices by a firmware.

It also has a hardwired (to 0s) the least significant bits of the
base address register which is represented by the only 64-bit BAR0.
It means that OS mustn't reallocate the BAR.

On top of that in some cases P2SB is represented by function 0 on PCI
slot (in terms of B:D.F) and according to the PCI specification any
other function can't be seen until function 0 is present and visible.

In the PCI configuration space of P2SB device the full 32-bit register
is allocated for the only purpose of hiding the entire P2SB device. As
per [3]:

  3.1.39 P2SB Control (P2SBC)—Offset E0h

  Hide Device (HIDE): When this bit is set, the P2SB will return 1s on
  any PCI Configuration Read on IOSF-P. All other transactions including
  PCI Configuration Writes on IOSF-P are unaffected by this. This does
  not affect reads performed on the IOSF-SB interface.

This doesn't prevent MMIO accesses, although preventing the OS from
assigning these addresses. The firmware on the affected platforms marks
the region as unusable (by cutting it off from the PCI host bridge
resources) as depicted in the Apollo Lake example below:

  PCI host bridge to bus 0000:00
  pci_bus 0000:00: root bus resource [io  0x0070-0x0077]
  pci_bus 0000:00: root bus resource [io  0x0000-0x006f window]
  pci_bus 0000:00: root bus resource [io  0x0078-0x0cf7 window]
  pci_bus 0000:00: root bus resource [io  0x0d00-0xffff window]
  pci_bus 0000:00: root bus resource [mem 0x7c000001-0x7fffffff window]
  pci_bus 0000:00: root bus resource [mem 0x7b800001-0x7bffffff window]
  pci_bus 0000:00: root bus resource [mem 0x80000000-0xcfffffff window]
  pci_bus 0000:00: root bus resource [mem 0xe0000000-0xefffffff window]
  pci_bus 0000:00: root bus resource [bus 00-ff]

The P2SB 16MB BAR is located at 0xd0000000-0xd0ffffff memory window.

The generic solution
====================
The generic solution for all cases when we need to access to the information
behind P2SB device is a library code where users ask for necessary resources
by demand and hence those users take care of not being run on the systems
where this access is not required.

The library provides the p2sb_bar() API to retrieve the MMIO of the BAR0 of
the device from P2SB device slot.

P2SB unconditional unhiding awareness
=====================================
Technically it's possible to unhide the P2SB device and devices on
the same PCI slot and access them at any time as needed. But there are
several potential issues with that:

 - the systems were never tested against such configuration and hence
   nobody knows what kind of bugs it may bring, especially when we talk
   about SPI NOR case which contains Intel FirmWare Image (IFWI) code
   (including BIOS) and already known to be problematic in the past for
   end users

 - the PCI by its nature is a hotpluggable bus and in case somebody
   attaches a driver to the functions of a P2SB slot device(s) the
   end user experience and system behaviour can be unpredictable

 - the kernel code would need some ugly hacks (or code looking as an
   ugly hack) under arch/x86/pci in order to enable these devices on
   only selected platforms (which may include CPU ID table followed by
   a potentially growing number of DMI strings

The future improvements
=======================
The future improvements with this code may go in order to gain some kind
of cache, if it's possible at all, to prevent unhiding and hiding many
times to take static information that may be saved once per boot.

The identification is DMI-based with a vendor specific way to tell them

Drivers for LEDs and Watchdogs will follow to make use of that platform
detection.

There is also some code to allow secondary drivers to find GPIO memory,
that needs to be in place because the pinctrl drivers do not come up.

Luke D. Jones 0f0ac158d2 platform/x86: asus-wmi: Add support for custom fan curves
Add support for custom fan curves found on some ASUS ROG laptops.

These laptops have the ability to set a custom curve for the CPU
and GPU fans via two ACPI methods.

This patch adds two pwm<N> attributes to the hwmon sysfs,
pwm1 for CPU fan, pwm2 for GPU fan. Both are under the hwmon of the
name `asus_custom_fan_curve`. There is no safety check of the set
fan curves - this must be done in userspace.

The fans have settings [1,2,3] under pwm<N>_enable:
1. Enable and write settings out
2. Disable and use factory fan mode
3. Same as 2, additionally restoring default factory curve.

Use of 2 means that the curve the user has set is still stored and
won't be erased, but the laptop will be using its default auto-fan
mode. Re-enabling the manual mode then activates the curves again.

Notes:
- pwm<N>_enable = 0 is an invalid setting.
- pwm is actually a percentage and is scaled on writing to device.

sound subsystem too.

Move these to include/linux/platform_data/x86/soc.h, so that
other code can use them too.

Linus Torvalds 75d6e7d9ce Nothing changed in the clk framework core this time around. We did get
some updates to the basic clk types to use determine_rate for the
 divider type and add a power of two fractional divider flag though.
 Otherwise, this is a collection of clk driver updates. More than half
 the diffstat is in the Qualcomm clk driver where we add a bunch of data
 to describe clks on various SoCs and fix bugs. The other big new thing
 in here is the Mediatek MT8192 clk driver. That's been under review for
 a while and it's nice to see that it's finally upstream.
 
 Beyond that it's the usual set of minor fixes and tweaks to clk drivers.
 There are some non-clk driver bits in here which have all been acked by

Luke D. Jones 98829e84dc asus-wmi: Add dgpu disable method
In Windows the ASUS Armory Crate program can enable or disable the
dGPU via a WMI call. This functions much the same as various Linux
methods in software where the dGPU is removed from the device tree.

However the WMI call saves the state of dGPU (enabled or not) and
this then changes the dGPU visibility in Linux with no way for
Linux users to re-enable it. We expose the WMI method so users can
see and change the dGPU ACPI state.

Samuel Čavoj ea856ec266 platform/x86: asus-wmi: Add support for SW_TABLET_MODE on UX360
The UX360CA has a WMI device id 0x00060062, which reports whether the
lid is flipped in tablet mode (1) or in normal laptop mode (0).

Add a quirk (quirk_asus_use_lid_flip_devid) for devices on which this
WMI device should be used to figure out the SW_TABLET_MODE state, as
opposed to the quirk_asus_use_kbd_dock_devid.

Additionally, the device needs to be queried on resume and restore
because the firmware does not generate an event if the laptop is put to
sleep while in tablet mode, flipped to normal mode, and later awoken.

It is assumed other UX360* models have the same WMI device. As such, the
quirk is applied to devices with DMI_MATCH(DMI_PRODUCT_NAME, "UX360").
More devices with this feature need to be tested and added accordingly.

The reason for using an allowlist via the quirk mechanism is that the new
WMI device (0x00060062) is also present on some models which do not have
a 360 degree hinge (at least FX503VD and GL503VD from Hans' DSTS
collection) and therefore its presence cannot be relied on.

Daniel Drake e3168b8743 platform/x86: asus-wmi: fix CPU fan control on recent products
Previously, asus-wmi was using the AGFN interface and FAN_CTRL device
for CPU fan control. However, this code has been found to be not fully
working on some recent products, and having checked the spec, these
interfaces are marked as being removed from future products currently
in development.

The replacement appears to be the CPU_FAN device, added in spec version
8.3 (March 2014) and present on many modern Asus laptops.

Add support for this device, and use it whenever it is detected.
The older approach based on AGFN and FAN_CTRL is used as a fallback
on products that do not have such device.

Other than switching between automatic and full speed, there is
no fan speed control through this new interface.

Daniel Drake 2889ffcfc2 platform/x86: asus-wmi: cleanup AGFN fan handling
The asus-wmi driver currently uses the "AGFN" interface and
the FAN_CTRL device for fan control. According to the spec, this
interface is very dated and marked as pending removal from products
currently in development.

Clean up the way that the AGFN fan is detected and handled, also
preparing the driver for the introduction of an alternate fan
control method needed to support recent Asus products.

Not anticipating further development of this interface, simplify
the code by dropping any notion of being able to control multiple
AGFN fans (this was already limited to just a single fan through only
exposing a single fan in sysfs).

Check for the presence of AGFN fans at probe time, simplifying the code
flow in asus_hwmon_sysfs_is_visible().

Daniel Drake 9af93db9e1 platform/x86: asus: Rename "fan mode" to "fan boost mode"
The Asus WMI spec indicates that the function being controlled here
is called "Fan Boost Mode". The user-facing documentation also calls it
this.

The spec uses the term "fan mode" is used to refer to other things,
including functionality expected to appear on future products.
We missed this before as we are not dealing with the most readable of
specs, and didn't forsee any confusion around shortening the name.

Rename "fan mode" to "fan boost mode" to improve consistency with the
spec and to avoid a future naming conflict.

There is no interface breakage here since this has yet to be included
in an official kernel release. I also updated the kernel version listed
under ABI accordingly.

Linus Torvalds 5516745311 platform-drivers-x86 for v5.3-1
ASUS WMI driver got a big refactoring in order to support the TUF Gaming
 laptops. Besides that, the regression with backlight being permanently off
 on various EeePC laptops has been fixed.
 
 Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
 X axis being inverted. This has been fixed.
 
 Intel PMC core driver has been extended to be ACPI enumerated
 if the DSDT provides device with _HID "INT33A1". This allows
 to convert the driver to be pure platform and support new hardware
 purely based on ACPI DSDT.
 
 From now on the Intel Speed Select Technology is supported thru
 a corresponding driver. This driver provides an access to the features
 of the ISST, such as Performance Profile, Core Power, Base frequency and
 Turbo Frequency.
 
 Mellanox platform drivers has been refactored and now extended
 to support more systems, including new coming ones.
 
 The OLPC XO-1.75 platform is now supported.
 
 CB4063 Beckhoff Automation board is using PMC clocks,
 provided via pmc_atom driver, for ethernet controllers in a way
 that they can't be managed by the clock driver. The quirk
 has been extended to cover this case.
 
 Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
 the information of Chuwi Hi10 Air has been fixed to cover more models
 based on the same platform.
 
 Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it
 has been provided. It required some extension of the generic WMI library,
 which allows to propagate opaque context to the ->probe() of the
 individual drivers.
 
 This release includes debugfs clean up from Greg KH for several drivers
 that drop return code check and make debugfs absence or failure non-fatal.
 
 Miscellaneous fixes here and there, mostly for Acer WMI and
 various Intel drivers.
 
 The listed below commits are duplicated due to previously pushed fixes in v5.2 cycle:

Pull x86 platform driver updates from Andy Shevchenko:
 "Gathered a bunch of x86 platform driver changes. It's rather big,
  since includes two big refactors and completely new driver:

   - ASUS WMI driver got a big refactoring in order to support the TUF
     Gaming laptops. Besides that, the regression with backlight being
     permanently off on various EeePC laptops has been fixed.

   - Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
     X axis being inverted. This has been fixed.

   - Intel PMC core driver has been extended to be ACPI enumerated if
     the DSDT provides device with _HID "INT33A1". This allows to
     convert the driver to be pure platform and support new hardware
     purely based on ACPI DSDT.

   - From now on the Intel Speed Select Technology is supported thru a
     corresponding driver. This driver provides an access to the
     features of the ISST, such as Performance Profile, Core Power, Base
     frequency and Turbo Frequency.

   - Mellanox platform drivers has been refactored and now extended to
     support more systems, including new coming ones.

   - The OLPC XO-1.75 platform is now supported.

   - CB4063 Beckhoff Automation board is using PMC clocks, provided via
     pmc_atom driver, for ethernet controllers in a way that they can't
     be managed by the clock driver. The quirk has been extended to
     cover this case.

   - Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
     the information of Chuwi Hi10 Air has been fixed to cover more
     models based on the same platform.

   - Xiaomi notebooks have WMI interface enabled. Thus, the driver to
     support it has been provided. It required some extension of the
     generic WMI library, which allows to propagate opaque context to
     the ->probe() of the individual drivers.

  This release includes debugfs clean up from Greg KH for several
  drivers that drop return code check and make debugfs absence or
  failure non-fatal.

  Also miscellaneous fixes here and there, mostly for Acer WMI and
  various Intel drivers"

Yurii Pavlovskyi b096f626a6 platform/x86: asus-wmi: Switch fan boost mode
The WMI exposes a write-only device ID where up to three fan modes can be
switched on some laptops (TUF Gaming FX505GM). There is a hotkey
combination Fn-F5 that does have a fan icon, which is designed to toggle
between fan modes. The DSTS of the device ID returns information about the
presence of this capability and the presence of each of the two additional
fan modes as a bitmask (0x01 - overboost present, 0x02 - silent present)
[1].

Add a SysFS entry that reads the last written value and updates value in
WMI on write and a hotkey handler that toggles the modes taking into
account their availability according to DSTS.

Modes:
* 0x00 - normal or balanced,
* 0x01 - overboost, increased fan RPM,
* 0x02 - silent, decreased fan RPM

Yurii Pavlovskyi e0668f2888 platform/x86: asus-wmi: Improve DSTS WMI method ID detection
The DSTS method detection mistakenly selects DCTS instead of DSTS if
nothing is returned when the method ID is not defined in WMNB. As a result,
the control of keyboard backlight is not functional for TUF Gaming series
laptops. Implement detection based on _UID of the WMI device instead.

There is evidence that DCTS is handled by ACPI WMI devices that have _UID
ASUSWMI, whereas none of the devices without ASUSWMI respond to DCTS and
DSTS is used instead [1].

DSDT examples:

FX505GM (_UID ATK):
Method (WMNB, 3, Serialized)
{ ...
    If ((Local0 == 0x53545344))
    {
        ...
        Return (Zero)
    }
    ...
    // No return
}

K54C (_UID ATK):
Method (WMNB, 3, Serialized)
{ ...
    If ((Local0 == 0x53545344))
    {
        ...
        Return (0x02)
    }
    ...
    Return (0xFFFFFFFE)

Chris Chiu 487579bab8 platform/x86: asus-wmi: Add fn-lock mode switch support
Some of latest ASUS laptops support new fn-lock mode switching.
This commit detect whether if the fn-lock option is enabled in
BIOS setting, and toggle the fn-lock mode via a new WMI DEVID
0x00100023 when the corresponding notify code captured.

The ASUS fn-lock mode switch is activated by pressing Fn+Esc.
When on, keys F1 to F12 behave as applicable, with meanings
defined by the application being used at the time. When off,
F1 to F12 directly triggers hardware features, well known audio
volume up/down, brightness up/down...etc, which were triggered
by holding down Fn key and F-keys.

Because there's no way to retrieve the fn-lock mode via existing
WMI methods per ASUS spec, driver need to initialize and keep the
fn-lock mode by itself.
