Since the x86-android-tablets code uses platform_create_bundle() it cannot
use EPROBE_DEFER and the driver-core will translate EPROBE_DEFER to ENXIO.
Stop using EPROBE_DEFER instead log an error and return ENODEV, or for
non-fatal cases log a warning and return 0.

2 fixes for Lenovo tablets:
- The bq24190 charger on the Lenovo Yoga Tab2 830/1050 devices does not use
the crystal-cove PMIC charger IRQ, so these shouldn't use bq24190_modules
as that includes "intel_crystal_cove_charger"
- Both the Tab2 and the Tab3 devices have a SPI audio-codec which init()
attaches properties to, resp. the whole SPI device gets instantiated by
the x86-android-tablets code. This requires the "spi_pxa2xx_platform"
module to be loaded before init() runs

lenovo_yoga_tab2_830_1050_exit() only gets called after a successful
lenovo_yoga_tab2_830_1050_init() call so there is no need to check
if lenovo_yoga_tab2_830_1050_codec_[dev|pinctrl] are set.
Also change the exit() order to be the exact reverse of init().

Add support for the Acer Iconia One 8 A1-840 (non FHD version) tablet.
This tablet has the usual issues for tablets shipped with Android as
factory OS. The DSDT is broken in various ways, so i2c_clients for
various devices as well as the INT3496 platform-device for OTG extcon
handling need to be instantiated manually by x86-android-tablets.
This tablet is special in that it is the first time a Bay Trail device
has been found to use the Dollar Cove TI PMIC and the first time that
the PMIC's Coulomb Counter is used as fuel-gauge.
So far this PMIC has only been used together with Cherry Trail SoCs
and always in combination with a separate full-featured fuel-gauge IC.

Acer has several x86 based Android tablets which need x86-android-tablets
support to work around their broken ACPI tables.
At the moment x86-android-tablets only support one model, move this to
its own file before adding support for more models to avoid needing to
move more code around later.

software_node_register_node_group() / software_node_unregister_node_group()
both accept a NULL node-group as argument.
So there is no need to check for the node-group being NULL before calling
these functions, remove the checks to simplify the code.
Note the "if (gpio_button_swnodes)" check for registering is kept because
that also guards the creation of a gpio-button platform-device.

Now that gpiolib supports software nodes to describe GPIOs, switch the

Since the tablets are using either Baytrail or Cherryview GPIO
controllers x86_dev_info structure has been extended to carry gpiochip
type information so that the code can instantiate correct set of
software nodes representing the GPIO chip.
Because this adds a new point of failure in x86_android_tablet_probe(),
x86_android_tablet_remove() is rearranged to handle cases where battery
swnode has not been registered yet, and registering of GPIO lookup
tables is moved earlier as it can not fail.

through the acpi_quirk_skip_i2c_client_enumeration().

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.

The UART used for the Bluetooth HCI on the Vexia EDU ATLA 10 is enumerated

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.

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.

PCI parent devname()
On the Vexia EDU ATLA 10 tablet, which ships with Android + a custom Linux
(guadalinex) using the custom Android kernel the I2C controllers are not
enumerated as ACPI devices as they typically are.
Instead they are enumerated as PCI devices which do not have ACPI firmware
nodes associated with them, so getting the i2c_adapter by the ACPI path of
its firmware node does not work.
Add support for getting the i2c_adapter by the devname() of its PCI parent
instead.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/platform/x86/ to use
.remove(), with the eventual goal to drop struct
platform_driver::remove_new(). As .remove() and .remove_new() have the
same prototypes, conversion is done by just changing the structure
member name in the driver initializer.
While touching these files, make indention of the struct initializer
consistent in several files.

platform_device_register() errors
x86_android_tablet_remove() frees the pdevs[] array, so it should not
be used after calling x86_android_tablet_remove().
When platform_device_register() fails, store the pdevs[x] PTR_ERR() value
into the local ret variable before calling x86_android_tablet_remove()
to avoid using pdevs[] after it has been freed.

buttons LED
The "input-events" LED trigger used to turn on the backlight LEDs had to
be rewritten to use led_trigger_register_simple() + led_trigger_event()
to fix a serious locking issue.
This means it no longer supports using blink_brightness to set a per LED
brightness for the trigger and it no longer sets LED_CORE_SUSPENDRESUME.
Adjust the MiPad 2 bottom bezel touch buttons LED class device to match:
1. Make LED_FULL the maximum brightness to fix the LED brightness
being very low when on.
2. Set flags = LED_CORE_SUSPENDRESUME.

less strict
There are 2G and 4G RAM versions of the Lenovo Yoga Tab 3 X90F and it
turns out that the 2G version has a DMI product name of
"CHERRYVIEW D1 PLATFORM" where as the 4G version has
"CHERRYVIEW C0 PLATFORM". The sys-vendor + product-version check are
unique enough that the product-name check is not necessary.
Drop the product-name check so that the existing DMI match for the 4G
RAM version also matches the 2G RAM version.

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).

3. Put the fwnode link for red before green in ktd2026_node_group[] so that
multi_index becomes "red green blue".
