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.

Replace the custom arizona_of_get_type() function with the generic device_get_match_data() helper. Besides being a nice cleanup this also makes it easier to add support for binding to ACPI enumerated devices.

While at it also fix a possible NULL pointer deref of the id argument to the probe functions (this could happen on e.g. manual driver binding through sysfs).

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].

From: Pierre-Louis Bossart pierre-louis.bossart@linux.intel.com

Add a new ASoc Machine driver for Intel Baytrail platforms with a Wolfson Microelectronics WM5102 codec.

This is based on a past contributions [1] from Paulo Sergio Travaglia pstglia@gmail.com based on the Levono kernel [2] combined with insights in things like the speaker GPIO from the android-x86 android port for the Lenovo Yoga Tablet 2 1051F/L [3].

[1] https://patchwork.kernel.org/project/alsa-devel/patch/593313f5.3636c80a.50e0... [2] https://github.com/lenovo-yt2-dev/android_kernel_lenovo_baytrail/blob/cm-12.... [3] https://github.com/Kitsune2222/Android_Yoga_Tablet_2-1051F_Kernel

The original machine driver from the Android ports was a crude modified copy of bytcr_rt5640.c adjusted to work with the WM5102 codec. This version has been extensively reworked to:

1. Remove all rt5640 related quirk handling. to the best of my knowledge this setup is only used on the Lenovo Yoga Tablet 2 series (8, 10 and 13 inch models) which all use the same setup. So there is no need to deal with all the variations with which we need to deal on rt5640 boards.

2. Rework clock handling, properly turn off the FLL and the platform-clock when they are no longer necessary and don't reconfigure the FLL unnecessarily when it is already running. This fixes a number of: "Timed out waiting for lock" warnings being logged.

3. Add the GPIO controlled Speaker-VDD regulator as a DAPM_SUPPLY

This only adds the machine driver and ACPI hooks, the BYT-CR detection quirk which these devices need will be added in a separate patch.
