3 daysplatform/x86: x86-android-tablets: Make Lenovo Yoga Tab 3 X90F DMI match ↵Hans de Goede1-1/+0
less strict [ Upstream commit a3379eca24a7da5118a7d090da6f8eb8611acac8 ] 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.

2024-05-14platform/x86: x86-android-tablets: Create LED device for Xiaomi Pad 2 bottom ↵Hans de Goede1-0/+47
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).

2024-04-15platform/x86: x86-android-tablets: Unregister devices in reverse orderHans de Goede1-4/+4
Not all subsystems support a device getting removed while there are still consumers of the device with a reference to the device. One example of this is the regulator subsystem. If a regulator gets unregistered while there are still drivers holding a reference a WARN() at drivers/regulator/core.c:5829 triggers, e.g.: WARNING: CPU: 1 PID: 1587 at drivers/regulator/core.c:5829 regulator_unregister Hardware name: Intel Corp. VALLEYVIEW C0 PLATFORM/BYT-T FFD8, BIOS BLADE_21.X64.0005.R00.1504101516 FFD8_X64_R_2015_04_10_1516 04/10/2015 RIP: 0010:regulator_unregister Call Trace: <TASK> regulator_unregister devres_release_group i2c_device_remove device_release_driver_internal bus_remove_device device_del device_unregister x86_android_tablet_remove On the Lenovo Yoga Tablet 2 series the bq24190 charger chip also provides a 5V boost converter output for powering USB devices connected to the micro USB port, the bq24190-charger driver exports this as a Vbus regulator. On the 830 (8") and 1050 ("10") models this regulator is controlled by a platform_device and x86_android_tablet_remove() removes platform_device-s before i2c_clients so the consumer gets removed first. But on the 1380 (13") model there is a lc824206xa micro-USB switch connected over I2C and the extcon driver for that controls the regulator. The bq24190 i2c-client *must* be registered first, because that creates the regulator with the lc824206xa listed as its consumer. If the regulator has not been registered yet the lc824206xa driver will end up getting a dummy regulator. Since in this case both the regulator provider and consumer are I2C devices, the only way to ensure that the consumer is unregistered first is to unregister the I2C devices in reverse order of in which they were created. For consistency and to avoid similar problems in the future change x86_android_tablet_remove() to unregister all device types in reverse order.

Yogabook1 X90 After commit 4014ae236b1d ("platform/x86: x86-android-tablets: Stop using gpiolib private APIs") the touchscreen in the keyboard half of the Lenovo Yogabook1 X90 stopped working with the following error: Goodix-TS i2c-goodix_ts: error -EBUSY: Failed to get irq GPIO The problem is that when getting the IRQ for instantiated i2c_client-s from a GPIO (rather then using an IRQ directly from the IOAPIC), x86_acpi_irq_helper_get() now properly requests the GPIO, which disallows other drivers from requesting it. Normally this is a good thing, but the goodix touchscreen also uses the IRQ as an output during reset to select which of its 2 possible I2C addresses should be used. Add a new free_gpio flag to struct x86_acpi_irq_data to deal with this and release the GPIO after getting the IRQ in this special case.

Pro YT3-X90F Fix the maximum brightness being much too low on the Yoga Tab 3 Pro. The LP8557 backlight controller can either be configured to multiply its PWM input and the I2C register set level (requiring both to be at 100% for 100% output); or to only take the I2C register set level into account. Multiplying the 2 levels is useful because this will turn off the backlight when the panel goes off and turns off its PWM output. But on the YT3-X90F the panel's PWM output defaults to a duty-cycle of much less then 100%, severely limiting max brightness. In this case the LP8557 should be configured to only take the I2C register into account and the i915 driver must turn off the backlight separately using a VBT MIPI sequence to turn off the backlight.

2023-04-06platform/x86: x86-android-tablets: Use LP8557 in direct mode on both the ↵Hans de Goede2-25/+7
Yoga 830 and the 1050 Both the Lenovo Yoga Tablet 2 830 and 1050 models use an TI LP8557 LED backlight controller. On the 1050 the LP8557's PWM input is connected to the PMIC's PWM output and everything works fine with the defaults programmed into the LP8557 by the BIOS. But on the 830 the LP8557's PWM input is connected to a PWM output coming from the LCD panel's controller. The Android code has a hack in the i915 driver to write the non-standard DSI reg 0x9f with the desired backlight level to set the duty-cycle of the LCD's PWM output. To avoid having to have a similar hack in the mainline kernel the LP8557 entry in lenovo_yoga_tab2_830_1050_i2c_clients instead just programs the LP8557 to directly set the level, ignoring the PWM input. So far we have only been instantiating the LP8557 i2c_client for direct backlight control on the 830 model. But we want hide/disable the intel_backlight interface on the 830 model to avoid having 2 backlight interfaces for the same LCD panel. And the 830 and 1050 share the same DMI strings. So this will hide the intel_backlight interface on the 1050 model too. To avoid this causing problems make the backlight handling consistent between the 2 models and always directly use the LP8557. This also simplifies the code.

2023-03-07platform/x86: x86-android-tablets: Add support for the Dolby button on Peaq ↵Hans de Goede3-0/+37
C1010 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.
