Simplify the logic of ASIC health discovery.
ASIC device can indicate its health state as a good, booting or dormant.
During ASIC reset the device is dropped to dormant state and should get to
the stable good health state through the intermediate booting state.
The sequence for getting to the steady state health after reset is:
(dormant -> booting -> good)+.
Initial implementation assumes that ?good? within this sequence is always
repeated twice and device is getting steady state only after the second
?good?. This patch removes this dependency, since the second ?good? is
received because of the noise on line and can be ignored. Device reaches
steady state after the first ?good? is received.

Fix return code check for "max brightness" ACPI call.
The Dell laptop ACPI video brightness control is not present on dell
laptops anymore, but was present in older kernel versions.
The code that checks the return value is incorrect since the SMM
refactoring.
The old code was:
if (buffer->output[0] == 0)
Which was changed to:
ret = dell_send_request(...)
if (ret)
However, dell_send_request() will return 0 if buffer->output[0] == 0,
so we must change the check to:
if (ret == 0)
This issue was found on a Dell M4800 laptop, and the fix tested on it
as well.

The Dell laptop I have has an ACPI that sends 0xCB and 0xCC on entering
tablet mode. On exiting tablet mode it sends 0xCA and 0xCD. Based on:
http://www.traby.de/medion/DSDT/dsdt.dslhttps://gist.github.com/jprvita/5737de3cbb670e80973b7d4e51c38ab6https://osdn.net/projects/android-x86/scm/git/kernel/commits/
7cbe5a330687b851f32dd9f1048a6ce182d0ff44
It appears that 0xCA and 0xCB are about dock mode, which for my
convertible laptop seems questionably tied to whether I've put
the laptop in tablet or laptop mode. I previously proposed no-oping
0xCA and 0xCB but this revised change attempts to add support for
detecting dock mode--this detection will essentially be broken for
my laptop (the main workaround would be for 0xCA and 0xCB to be used
to provoke a query of the VGBS method that reports the current dock &
tablet mode [which is accurately reported on my laptop but based on
the prior workarounds in the driver it apparently can't be trusted
for all systems]).

In some of the recent platforms, it is possible that stand alone methods
for HEBC() or other methods used in this driver may not exist. In this
case intel-hid driver will fail to load and power button will not be
functional.
It is also possible that some quirks in this driver added for some
platforms may have same issue in loading intel-hid driver.
There is an update to the ACPI details for the HID event filter driver.
In the updated specification a _DSM is added, which has separate function
indexes for each of the previous stand alone methods.
This change brings in support for the _DSM and allows usage of function
index for corresponding stand alone methods.
Details of Device Specific Method:
Intel HID Event Filter Driver _DSM UUID:
eeec56b3-4442-408f-a792-4edd4d758054
• Function index 0: Returns a buffer with a bit-field representing the

--------------------------------
1 BTNL
2 HDMM
3 HDSM
4 HDEM
5 BTNS
6 BTNE
7 HEBC
8 VGBS
9 HEBC
One significant change is to query the supported methods implemented on
the platform. So the previous HEBC() has two variants. HEBC v1 and
HEBC v2. The v2 version allowed further define which of the 5-button
are actually defined by the platform. HEBC v2 support is only available
via new DSM.

Here is the big USB pull request for 4.18-rc1.
Lots of stuff here, the highlights are:
- phy driver updates and new additions
- usual set of xhci driver updates
- normal set of musb updates
- gadget driver updates and new controllers
- typec work, it's getting closer to getting fully out of the
staging portion of the tree.
- lots of minor cleanups and bugfixes.
All of these have been in linux-next for a while with no reported
issues.

Further changes from Dmitry related to the removal of platform data from
atmel_mxt_ts and chromeos_laptop. This time, we have some changes that
teach chromeos_laptop how to supply acpi properties for some input devices
so that the peripheral driver doesn't have to do dmi matching on some
Chromebook platforms.
Also adds the Chromebook Tablet switch driver, which is useful for x86
convertible Chromebooks.
Other misc. cleanup.
Thanks,
Benson

platform/chrome: Use to_cros_ec_dev more broadly

The XPS 13 9370 doesn't expose the necessary KBD_LED_AC_TOKEN in
the BIOS, so the driver thinks it cannot adjust the AC keyboard
backlight timeout. This patch adds a quirk to fix this until
Dell adds the missing token to the BIOS.

There are two new events generated by dell-wmi, rfkill and fn-lock, from
Dell Systems.
When Fn-lock hotkey gets pressed to switch to function mode:
[85951.591542] dell_wmi: Unknown key with type 0x0010 and code 0xe035
pressed
[85951.591546] dell_wmi: Unknown key with type 0x0010 and code 0x0000
pressed
When Fn-lock hotkey gets pressed to switch to multimedia mode:
[85956.667686] dell_wmi: Unknown key with type 0x0010 and code 0xe035
pressed
[85956.667690] dell_wmi: Unknown key with type 0x0010 and code 0x0001
pressed
When radio hotkey gets pressed:
[85974.430220] dell_wmi: Unknown key with type 0x0010 and code 0xe008
pressed
These events are for notification purpose, so we can ignore them.
This patch is tested on XPS 9370.

Add LED platform driver activation from mlx-platform. This LED driver uses
the same regmap infrastructure as others Mellanox platform drivers, so LED
specific registers description is added.
System LED configuration depends on system type. To support all the
relevant types per system type LED descriptions are defined for passing
to LED platform driver.

Add new ODM system types, matched according to DMI_BOARD_NAME. The
supported ODM Ids are: VMOD0001, VMOD0002, VMOD0003, VMOD0004, VMOD0005.
Patch does not introduce new systems, but allows to ODM companies to set
DMI_BOARD_VENDOR and DMI_PRODUCT_NAME on their own. It assumes that ODM
company can't change DMI_BOARD_NAME.
