platform/x86: x86-android-tablets: Add Vexia Edu Atla 10 tablet 5V data
The Vexia EDU ATLA 10 tablet comes in 2 different versions with
significantly different mainboards. The only outward difference is that
the charging barrel on one is marked 5V and the other is marked 9V.
Both are x86 ACPI tablets which ships with Android x86 as factory OS.
with a DSDT which contains a bunch of I2C devices which are not actually
there, causing various resource conflicts. Enumeration of these is skipped
through the acpi_quirk_skip_i2c_client_enumeration().
Extend the existing support for the 9V version by adding support for
manually instantiating the I2C devices which are actually present on
the 5V version by adding the necessary device info to
the x86-android-tablets module.

platform/x86: x86-android-tablets: Add Vexia EDU ATLA 10 EC battery driver
The Vexia EDU ATLA 10 tablet has an embedded controller instead of
giving the os direct access to the charger + fuel-gauge ICs as is normal
on tablets designed for Android.
There is ACPI Battery device in the DSDT using the EC which should work
except that it expects the I2C controller to be enumerated as an ACPI
device and the tablet's BIOS enumerates all LPSS devices as PCI devices
(and changing the LPSS BIOS settings from PCI -> ACPI does not work).
Add a power_supply class driver for the Atla 10 EC to expert battery info
to userspace. This is made part of the x86-android-tablets directory and
Kconfig option because the i2c_client it binds to is instantiated by
the x86-android-tablets kmod.

platform/x86: x86-android-tablets: Add Bluetooth support for Vexia EDU ATLA 10
The UART used for the Bluetooth HCI on the Vexia EDU ATLA 10 is enumerated
as a PCI device, but the ODBA7823 ACPI fwnode for the HCI expects it to
use the more standard ACPI enumeration mode.
So Bluetooth does not work out of the box. Add x86_serdev_info to make
the x86-android-tablets manually associate the fwnode with the UART.

platform/x86: x86-android-tablets: Add support for getting serdev-controller by PCI parent
On the Vexia EDU ATLA 10 tablet, which ships with Android + a custom Linux
(guadalinex) using the custom Android kernel the UART controllers are not
enumerated as ACPI devices as they typically are.
Instead they are enumerated through PCI and getting the serdev-controller
by ACPI HID + UID does not work.
Add support for getting the serdev-controller by the PCI devfn of its
parent instead.
This also renames the use_pci_devname flag to use_pci since the former
name now no longer is accurate.

platform/x86: x86-android-tablets: Add support for Vexia EDU ATLA 10 tablet
Add support for the Vexia EDU ATLA 10 tablet, Android 4.2/4.4 + Guadalinex
Ubuntu tablet distributed to schools in the Spanish Andalucía region.
Besides the usual broken DSDT issues this tablet is special because all
its LPSS island peripherals are enumerated as PCI devices rather then as
ACPI devices as they typically are.
At the same time there are disabled (_STA=0) ACPI devices for
the peripherals and child ACPI devices for e.g. attached I2C/SDIO devices
are children of these disabled ACPI devices and thus will not be used
by Linux since the parent is disabled.
So besides the usual manual i2c-client instantiation for accel/touchscreen
this tablet also requires manual i2c-client instantiation for the codec
and for the PMIC.
Also it seems the mainboard was designed for Windows not Android, so
it has an I2C attached embedded controller instead of allowing direct
access to the charger + fuel-gauge chips as is usual with Android boards.
Normally when there is an embedded controller, there also is ACPI battery
support, but since this shipped with Android that is missing and Linux
needs to have a power_supply class driver talking directly to the EC.

platform/x86: x86-android-tablets: Create LED device for Xiaomi Pad 2 bottom bezel touch buttons
The Xiaomi [Mi]Pad 2 has 3 menu / home / back capacitive touch-buttons
on its bottom bezel. These are backlit by LEDs attached to a TPS61158 LED
controller which is controlled by the "pwm_soc_lpss_2" PWM output.
Create a LED class device for this, using the new input-events trigger
as default trigger so that the buttons automatically light up on any
input activity.
Note alternatively a "leds_pwm" platform device could be created together
with the necessary fwnode_s_ and a fwnode link to the PWM controller.
There are 2 downsides to this approach:
1. The code would still need to pwm_get() the PWM controller to get/attach
a fwnode for the PWM controller fwnode link and setting up the necessary
fwnodes is non-trivial. So this would likely require more code then simply
registering the LED class device directly.
2. Currently the leds_pwm driver and its devicetree bindings do not support
limiting the maximum dutycycle to less then 100% which is required in this
case (the leds_pwm driver can probably be extended to allow this).
