* mfd: arizona-spi: Set pdata.hpdet_channel for ACPI enumerated devsHans de Goede2023-11-011-0/+3
| | | | | | | | | | | | | | | | | | | | | | Commit 9e86b2ad4c11 changed the channel used for HPDET detection (headphones vs lineout detection) from being hardcoded to ARIZONA_ACCDET_MODE_HPL (HP left channel) to it being configurable through arizona_pdata.hpdet_channel the DT/OF parsing added for filling arizona_pdata on devicetree platforms ensures that arizona_pdata.hpdet_channel gets set to ARIZONA_ACCDET_MODE_HPL when not specified in the devicetree-node. But on ACPI platforms where arizona_pdata is filled by arizona_spi_acpi_probe() arizona_pdata.hpdet_channel was not getting set, causing it to default to 0 aka ARIZONA_ACCDET_MODE_MIC. This causes headphones to get misdetected as line-out on some models. Fix this by setting hpdet_channel = ARIZONA_ACCDET_MODE_HPL.

* mfd: arizona: Remove #ifdef guards for PM related functionsPaul Cercueil2022-12-071-1/+1
| | | | | | | | | | | | | | | | | Only export the arizona_pm_ops if CONFIG_PM is set, but leave the suspend/resume functions (and related code) outside #ifdef guards. If CONFIG_PM is not set, the arizona_pm_ops will be defined as "static __maybe_unused", and the structure plus all the callbacks will be automatically dropped by the compiler. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.

| * mfd: arizona-spi: Add Android board ACPI table handlingHans de Goede2022-03-231-1/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | x86/ACPI boards with an arizona WM5102 codec ship with either Windows or Android as factory installed OS. The ACPI fwnode for the codec on Android boards misses 2 things compared to the Windows boards (this is hardcoded in the Android board kernels): 1. There is no CLKE ACPI method to enabe the 32 KHz clock the codec needs for jack-detection. 2. The GPIOs used by the codec are not listed in the fwnode for the codec. The ACPI tables on x86/ACPI boards shipped with Android being incomplete happens a lot. The special drivers/platform/x86/x86-android-tablets.c module contains DMI based per model handling to compensate for this. This module will enable the 32KHz clock through the pinctrl framework to fix 1. and it will also register a gpio-lookup table for all GPIOs needed by the codec + machine driver, including the GPIOs coming from the codec itself. Add an arizona_spi_acpi_android_probe() function which waits for the x86-android-tablets to have set things up before continue with probing the arizona WM5102 codec.

* | spi: make remove callback a void functionUwe Kleine-König2022-02-091-3/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | The value returned by an spi driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

* mfd: arizona: Add support for ACPI enumeration of WM5102 connected over SPIHans de Goede2021-02-041-0/+127
| | | | | | | | | | | | | | | | | | | | The Intel Bay Trail (x86/ACPI) based Lenovo Yoga Tablet 2 series use a WM5102 codec connected over SPI. Add support for ACPI enumeration to arizona-spi so that arizona-spi can bind to the codec on these tablets. This is loosely based on an earlier attempt (for Android-x86) at this by Christian Hartmann, combined with insights in things like the speaker GPIO from the android-x86 android port for the Lenovo Yoga Tablet 2 1051F/L [1].

* mfd: arizona: Add MODULE_SOFTDEP("pre: arizona_ldo1")Hans de Goede2021-02-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The (shared) probing code of the arizona-i2c and arizona-spi modules takes the following steps during init: 1. Call mfd_add_devices() for a set of early child-devices, this includes the arizona_ldo1 device which provides one of the core-regulators. 2. Bulk enable the core-regulators. 3. Read the device id. 4. Call mfd_add_devices() for the other child-devices. This sequence depends on 1. leading to not only the child-device being created, but also the driver for the child-device binding to it and registering its regulator. This requires the arizona_ldo1 driver to be loaded before the shared probing code runs. Add a softdep for this to both modules to ensure that this requirement is met. Note this mirrors the existing MODULE_SOFTDEP("pre: wm8994_regulator") in the wm8994 code, which has a similar init sequence.
