sound updates for 4.21
There are no intensive changes in both ALSA and ASoC core parts while
rather most of changes are a bunch of driver fixes and updates.
A large diff pattern appears in ASoC TI part which now merges both
OMAP and DaVinci stuff, but the rest spreads allover the places.
Note that this pull request includes also some updates for LED trigger
and platform drivers for mute LEDs, appearing in the diffstat as well.
Some highlights:
ASoC:
- Preparatory work for merging the audio-graph and audio-graph-scu
cards
- A merge of TI OMAP and DaVinci directories, as both product lines
get merged together. Also including a few architecture changes as
well.
- Major cleanups of the Maxim MAX9867 driver
- Small fixes for tablets & co with Intel BYT/CHT chips
- Lots of rsnd updates as usual
- Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S
controllers
HD-audio:
- Introduce audio-mute LED trigger for replacing the former hackish
dynamic binding
- Huawei WMI hotkey and mute LED support
- Refactoring of PM code and display power controls
- Headset button support in the generic jack code
- A few updates for Tegra
- Fixups for HP EliteBook and ASUS UX391UA
- Lots of updates for Intel ASoC HD-audio, including the improved DSP
detection and the fallback binding from ASoC SST to legacy HD-audio
controller drivers
Others:
- Updates for FireWire TASCAM and Fireface devices, some other fixes
- A few potential Spectre v1 fixes that are all trivial

platform/x86: thinkpad_acpi: Drop superfluous exported function
Since we've switched to the LED trigger for binding with HD-audio, we can drop the exported function as well as the whole linux/thinkpad_acpi.h. The own TPACPI_LED_MUTE and TPACPI_LED_MICMUTE definitions are replaced with the identical ones for LEDS, i.e. LED_AUDIO_MUTE and LED_AUDIO_MICMUTE, respectively. They are no longer needed as referred only locally.

platform/x86: thinkpad_acpi: Add audio mute LED classdev support
In the upcoming change, the binding of audio mute / mic-mute LED controls will be switched with LED trigger. This patch is the last piece of preparation: adding the audio mute / mic-mute LED class devices to thinkpad_acpi driver. Two devices, platform::mute and platform::micmute, will be added for controlling the mute LED and mic-mute LED, respectively. The new prefix "platform" is the suggestion by upstream for indicating the generic laptop attribute. Also this selects CONFIG_LEDS_TRIGGERS and CONFIG_LEDS_TRIGGERS_AUDIO unconditionally. Strictly speaking, these aren't 100% mandatory, but leaving these manual selections would lead to a functional regression easily once after converting from the dynamic symbol binding to the LEDs trigger in a later patch.

platform/x86: thinkpad_acpi: Change the keymap for Favorites hotkey
The keycode KEY_FAVORITES(0x16c) used in thinkpad_acpi driver is too
big (out of range > 255) for xorg to handle.
xkeyboard-config has already mapped KEY_BOOKMARKS(156) to
XF86Favorites:
keycodes/evdev:
<I164> = 164; // #define KEY_BOOKMARKS 156
symbols/inet:
key <I164> { [ XF86Favorites ] };
So change the keymap to KEY_BOOKMARKS for Favorites hotkey.

platform-drivers-x86 for v4.19-1
The driver for Silead touchscreen configurations has been renamed from silead_dmi to touchscreen_dmi since it starts supporting other touchscreens which require some DMI quirks. At the same release cycle it gets expanded to cover cases for Chuwi Vi10, ONDA V891W, Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets. Another bunch of changes is related to Mellanox platform code to allow user space to communicate with Mellanox for system control and monitoring purposes. The driver notifies user on hotplug device signal receiving. ASUS WMI drivers recognize lid flip action on UX360, and correctly toggles airplane mode LED. In addition the keyboard backlight toggle gets support. ThinkPad ACPI driver enables support for calculator key (on at least P52). It also has been fixed to support three characters model designators, which are used for modern laptops. Earlier the battery, marked as BAT1, on ThinkPad laptops has not been configured properly, which is fixed. On the opposite the multi-battery configurations now probed correctly. Dell SMBIOS driver starts working on some Dell servers which do not support token interface. The regression with backlight detection has also been fixed. In order to support dock mode on some laptops, Intel virtual button driver has been fixed. The last but not least is the fix to Intel HID driver due to changes in Dell systems that prevented to use power button.

platform/x86: thinkpad_acpi: Proper model/release matching
Modern Thinkpads have three character model designators. Previously, they

the wrong bytes from the ID string. This made the use of quirks for modern
machines impossible.

treewide: kzalloc() -> kcalloc()
The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:
kzalloc(a * b, gfp)
with:
kcalloc(a * b, gfp)
as well as handling cases of:
kzalloc(a * b * c, gfp)
with:
kzalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kzalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kzalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
The Coccinelle script used for this was:

platform/x86: thinkpad_acpi: silence false-positive-prone pr_warn
Do not consider unknown HKEY events in the 0x6000 range to be thermal warnings.

platform-drivers-x86 for v4.17-1
Dell SMBIOS driver fixed against memory leaks. The fujitsu-laptop driver is cleaned up and now supports hotkeys for Lifebook U7x7 models. Besides that the typo introduced by one of previous clean up series has been fixed. Specific to x86-based laptops HID device now supports KEY_ROTATE_LOCK_TOGGLE event which is emitted, for example, by Wacom MobileStudio Pro 13. Turbo MAX 3 technology is enabled for the rest of platforms that support Hardware-P-States feature which have core priority described by ACPI CPPC table. Mellanox on x86 gets better support of I2C bus in use including support of hotpluggable ones. Silead touchscreen is enabled on two tablet models, i.e Yours Y8W81 and I.T.Works TW701. From now on the second fan on Thinkpad P50 is supported. The topstar-laptop driver is reworked to support new models, in particular Topstar U931. Some of the changes had been already applied during v4.16 cycle and thus have a duplication here: - |

platform/x86: thinkpad_acpi: suppress warning about palm detection
This patch prevents the thinkpad_acpi driver from warning about 2 event codes returned for keyboard palm-detection. No behavioral changes, other than suppressing the warning in the kernel log. The events are still forwarded via acpi-netlink channels. We could, optionally, decide to forward the event through a input-switch on the tpacpi input device. However, so far no suitable input-code exists, and no similar drivers report such events. Hence, leave it an acpi event for now. Note that the event-codes are named based on empirical studies. On the ThinkPad X1 5th Gen the sensor can be found underneath the arrow key.

platform-drivers-x86 for v4.15-1
For this cycle we have quite an update for the Dell SMBIOS driver including WMI work to provide an interface for SMBIOS tokens via sysfs and WMI support for 2017+ Dell laptop models. SMM dispatcher code is split into a separate driver followed by a new WMI dispatcher. The latter provides a character device interface to user space. The pull request contains a merge of immutable branch from Wolfram Sang in order to apply a dependent fix to the Intel CherryTrail Battery Management driver. Other Intel drivers got a lot of cleanups. The Turbo Boost Max 3.0 support is added for Intel Skylake. Peaq WMI hotkeys driver gets its own maintainer and white list of supported models. Silead DMI is expanded to support few additional platforms. Tablet mode via GMMS ACPI method is added to support some ThinkPad tablets. Two commits appear here which were previously merged during the v4.14-rcX cycle: - |

platform/x86: thinkpad_acpi: Implement tablet mode using GMMS method
Many thinkpad laptops and convertibles provide the GMMS method to resolve how far the laptop has been opened and whether it has been converted into tablet mode. This allows reporting a more precise tablet mode state to userspace. The current implementation only reports a summarized tablet mode state which is triggered as soon as the input devices become unusable as they are folded away from the display. This will work on all models where the CMMD method was used previously and it may also work in other cases. Thanks to Peter Zhang of Lenovo for providing information on how to use the GMMS method to query the tablet mode.

platform/x86: thinkpad_acpi: Fix warning about deprecated hwmon_device_register
Use hwmon_device_register_with_groups instead of deprecated
hwmon_device_register and fix a dmesg warning.
This patch however changes the userspace API.
hwmon_device_register_with_groups takes `hwmon' name as an argument and
creates a name file in the `hwmon' device, not in the `platform_device'.
This allows us to remove custom `name' device attribute, but in order to
make lm-sensors happy we also have to move fans and thermal attributes
to the `hwmon' device.
Even though this patch changes userspace API, it's still compatible with
the lm-sensors. Starting with lm-sensors 3.0 (circa 2007), it looks at
both hwmon and the backing device for the name and other attributes.

This will allow userspace to monitor (poll) for brightness changes on these LEDs caused by the hotkey.

platform/x86: thinkpad_acpi: Use brightness_set_blocking callback for LEDs
Now a days the LED core can take care of executing brightness_set from a workqueue if it needs to sleep, make use of this and remove a bunch of DIY code for this. Since this commit removes the workqueue usage for LEDs, the led_sysfs_blink_set callback may now also sleep, this is fine.

platform/x86: thinkpad_acpi: Stop setting led_classdev brightness directly
There is no need to set the led_classdev's brightness value from its set_brightness callback, this is taken care of by the led-core and thinkpad_acpi really should not be mucking with it. Note that kbdlight_set_level_and_update() is still used by the old thinpad_acpi specific sysfs interface for the led, so we cannot remove it.

platform/x86: thinkpad_acpi: Adding new hotkey ID for Lenovo thinkpad
Recently we met an issue on lots of Lenovo thinkpad laptops (those laptops are not released to market yet), the issue is that the thinkpad_acpi.ko can't be automatically loaded as before. Through debugging, we found the HKEY_HID is LEN0268 instead of LEN0068 on those machines, and the MHKV is 0x200 instead of 0x100. So adding the new ID into the driver.

platform/x86: thinkpad_acpi: Move tablet detection into separate function
The hotkey events and ACPI handles used for detecting tablet mode on a few of the newer thinkpad models (Yoga X1 and the Yoga 260 specifically) have been changed around, so unfortunately this means we're definitely going to need to probe for multiple types of tablet mode support. Since the hotkey_init() is already a lot larger than it should be, let's split up this detection into its own function to make things a little easier to read. As well, since we're going to have multiple types of tablet modes, make hotkey_tablet into an enum so we can also use it to indicate the type of tablet mode reporting the machine supports.

Pull more power management and ACPI updates from Rafael Wysocki:
"This includes fixes on top of the previous batch of PM+ACPI updates
and some new material as well.
From the new material perspective the most significant are the driver
core changes that should allow USB devices to stay suspended over
system suspend/resume cycles if they have been runtime-suspended
already beforehand. Apart from that, ACPICA is updated to upstream
revision 20160108 (cosmetic mostly, but including one fixup on top of
the previous ACPICA update) and there are some devfreq updates the
didn't make it before (due to timing).
A few recent regressions are fixed, most importantly in the cpuidle
menu governor and in the ACPI backlight driver and some x86 platform
drivers depending on it.
Some more bugs are fixed and cleanups are made on top of that.

- Modify the driver core and the USB subsystem to allow USB devices
