platform/x86: x86-android-tablets: Add Lenovo Yoga Tablet 2 Pro 1380F/L data

2024-06-27T11:52:16Z

[ Upstream commit 3eee73ad42c3899d97e073bf2c41e7670a3c575c ] The Lenovo Yoga Tablet 2 Pro 1380F/L is a x86 ACPI tablet which ships with Android x86 as factory OS. Its DSDT 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(). Add support for manually instantiating the I2C + other devices which are actually present on this tablet by adding the necessary device info to the x86-android-tablets module.

platform/x86: x86-android-tablets: Add support for extra buttons on Cyberbook T116

2023-05-09T09:54:43Z

The Cyberbook T116 rugged tablet comes in both Windows and Android versions and even on the Android version the DSDT is mostly sane. This tablet has 2 extra general purpose buttons in the row with the power + volume-buttons, labeled P and F. Use the x86-android-tablets infra to create a gpio-button device for these 2 extra buttons.

platform/x86: x86-android-tablets: Add Nextbook Ares 8A data

2023-05-09T09:54:42Z

The Nextbook Ares 8A is a x86 ACPI tablet which ships with Android x86 as factory OS. Its DSDT 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(). Add support for manually instantiating the I2C devices which are actually present on this tablet by adding the necessary device info to the x86-android-tablets module. Note the Ares 8A is the Cherry Trail (CHT) model, the regular Ares 8 is Bay Trail (BYT) based and was already supported. This also updates the comments for the BYT model to point out this is the BYT model. Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20230429105057.7697-3-hdegoede@redhat.com

platform/x86: x86-android-tablets: Lenovo Yoga Book match is for YB1-X91 models only

2023-03-07T11:08:31Z

When support for instantiating an i2c-client for the fuel-gauge was added for the Windows based Yoga Book YB1-X91F/L models, the assumption was made that this would apply to the Android based YB1-X90F/L models too. But these have a completely different BIOS with completely different DMI strings. Update the existing YB1-X91 support to reflect that it only applies to the YB1-X91F/L models.

platform/x86: x86-android-tablets: Add support for the Dolby button on Peaq C1010

2023-03-07T11:08:31Z

The Peaq C1010 tablet has a special "Dolby" button. This button has a WMI interface, but this is broken in several ways: 1. It only supports polling 2. The value read on polling goes from 0 -> 1 for one poll on both edges of the button, with no way to tell which edge causes the poll to return 1. 3. It uses a non unique GUID (it uses the Microsoft docs WMI example GUID). There currently is a WMI driver for this, but it uses several kludges to work around these issues and is not entirely reliable due to 2. Replace the unreliable WMI driver by using the x86-android-tablets code to instantiate a gpio_keys device for this.

In order to have a single MODULE_DEVICE_TABLE(dmi, ...), while allowing splitting the board descriptions into multiple files, add a new separate file for the DMI match table.
