platform/x86: intel-vbtn: Support for tablet mode on HP Pavilion 13 x360 PC

[ Upstream commit 8b205d3e1bf52ab31cdd5c55f87c87a227793d84 ]

The Pavilion 13 x360 PC has a chassis-type which does not indicate it is
a convertible, while it is actually a convertible. Add it to the
dmi_switches_allow_list.

platform/x86: thinkpad_acpi: Add BAT1 is primary battery quirk for Thinkpad Yoga 11e 4th gen

2020-12-16T09:56:57+00:00

[ Upstream commit c986a7024916c92a775fc8d853fba3cae1d5fde4 ]

The Thinkpad Yoga 11e 4th gen with the N3450 / Celeron CPU only has
one battery which is named BAT1 instead of the expected BAT0, add a
quirk for this. This fixes not being able to set the charging tresholds
on this model; and this alsoe fixes the following errors in dmesg:

ACPI: \_SB_.PCI0.LPCB.EC__.HKEY: BCTG evaluated but flagged as error
thinkpad_acpi: Error probing battery 2
battery: extension failed to load: ThinkPad Battery Extension
battery: extension unregistered: ThinkPad Battery Extension

Note that the added quirk is for the "R0K" BIOS versions which are
used on the Thinkpad Yoga 11e 4th gen's with a Celeron CPU, there
is a separate "R0L" BIOS for the i3/i5 based versions. This may also
need the same quirk, but if that really is necessary is unknown.

platform/x86: thinkpad_acpi: Do not report SW_TABLET_MODE on Yoga 11e

2020-12-16T09:56:56+00:00

[ Upstream commit f2eae1888cf22590c38764b8fa3c989c0283870e ]

The Yoga 11e series has 2 accelerometers described by a BOSC0200 ACPI node.
This setup relies on a Windows service which reads both accelerometers and
then calculates the angle between the 2 halves to determine laptop / tent /
tablet mode and then reports the calculated mode back to the EC by calling
special ACPI methods on the BOSC0200 node.

The bmc150 iio driver does not support this (it involves double
calculations requiring sqrt and arccos so this really needs to be done
in userspace), as a result of this on the Yoga 11e the thinkpad_acpi
code always reports SW_TABLET_MODE=0, starting with GNOME 3.38 reporting
SW_TABLET_MODE=0 causes GNOME to:

1. Not show the onscreen keyboard when a text-input field is focussed
   with the touchscreen.
2. Disable accelerometer based auto display-rotation.

This makes sense when in laptop-mode but not when in tablet-mode. But
since for the Yoga 11e the thinkpad_acpi code always reports
SW_TABLET_MODE=0, GNOME does not know when the device is in tablet-mode.

Stop reporting the broken (always 0) SW_TABLET_MODE on Yoga 11e models
to fix this.

Note there are plans for userspace to support 360 degree hinges style
2-in-1s with 2 accelerometers and figure out the mode by itself, see:

platform/x86: toshiba_acpi: Fix the wrong variable assignment

2020-12-02T07:49:53+00:00

[ Upstream commit 2a72c46ac4d665614faa25e267c3fb27fb729ed7 ]

The commit 78429e55e4057 ("platform/x86: toshiba_acpi: Clean up
variable declaration") cleans up variable declaration in
video_proc_write(). Seems it does the variable assignment in the
wrong place, this results in dead code and changes the source code
logic. Fix it by doing the assignment at the beginning of the funciton.

platform/x86: thinkpad_acpi: Send tablet mode switch at wakeup time

[ Upstream commit e40cc1b476d60f22628741e53cf3446a29e6e6b9 ]

The lid state may change while the machine is suspended. As such, we may
need to re-check the state at wake-up time (at least when waking up from
hibernation).
Add the appropriate call to the resume handler in order to sync the
SW_TABLET_MODE switch state with the hardware state.

platform/x86: mlx-platform: Remove PSU EEPROM configuration

2020-10-29T08:57:44+00:00

[ Upstream commit c071afcea6ecf24a3c119f25ce9f71ffd55b5dc2 ]

Remove PSU EEPROM configuration for systems class equipped with
Mellanox chip Spectrume-2. Till now all the systems from this class
used few types of power units, all equipped with EEPROM device with
address space two bytes. Thus, all these devices have been handled by
EEPROM driver "24c32".
There is a new requirement is to support power unit replacement by "off
the shelf" device, matching electrical required parameters. Such device
could be equipped with different EEPROM type, which could be one byte
address space addressing or even could be not equipped with EEPROM.
In such case "24c32" will not work.

platform/x86: fix kconfig dependency warning for FUJITSU_LAPTOP

2020-10-14T08:33:03+00:00

[ Upstream commit afdd1ebb72051e8b6b83c4d7dc542a9be0e1352d ]

When FUJITSU_LAPTOP is enabled and NEW_LEDS is disabled, it results in the
following Kbuild warning:

WARNING: unmet direct dependencies detected for LEDS_CLASS
  Depends on [n]: NEW_LEDS [=n]
  Selected by [y]:
  - FUJITSU_LAPTOP [=y] && X86 [=y] && X86_PLATFORM_DEVICES [=y] && ACPI [=y] && INPUT [=y] && BACKLIGHT_CLASS_DEVICE [=y] && (ACPI_VIDEO [=n] || ACPI_VIDEO [=n]=n)

The reason is that FUJITSU_LAPTOP selects LEDS_CLASS without depending on
or selecting NEW_LEDS while LEDS_CLASS is subordinate to NEW_LEDS.

Honor the kconfig menu hierarchy to remove kconfig dependency warnings.
