2021-02-04mfd: arizona: Add support for ACPI enumeration of WM5102 connected over SPIHans de Goede
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].

2021-02-04mfd: arizona: Replace arizona_of_get_type() with device_get_match_data()Hans de Goede
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).

2021-02-04mfd: arizona: Add MODULE_SOFTDEP("pre: arizona_ldo1")Hans de Goede
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.

2021-01-15mfd/bus: sunxi-rsb: Make .remove() callback return voidUwe Kleine-König
The driver core ignores the return value of struct device_driver::remove because there is only little that can be done. To simplify the quest to make this function return void, let struct sunxi_rsb_driver::remove return void, too. All users already unconditionally return 0, this commit makes this obvious and ensures future users don't behave differently. To simplify even further, make axp20x_device_remove() return void instead of returning 0 unconditionally, too.

2020-12-15mfd: ab8500-debugfs: Remove the racy fiddling with irq_descThomas Gleixner
First of all drivers have absolutely no business to dig into the internals of an irq descriptor. That's core code and subject to change. All of this information is readily available to /proc/interrupts in a safe and race free way. Remove the inspection code which is a blatant violation of subsystem boundaries and racy against concurrent modifications of the interrupt descriptor. Print the irq line instead so the information can be looked up in a sane way in /proc/interrupts.

Instead of also adding the newly supported devices to the Kconfig description this patch removes the lengthy list. With future usage of the ACPI HIDs it will not be necessary to explicitly add support for each individual device to the driver and therefore the list would become incomplete anyway.

2020-11-19rtc: rework rtc_register_device() resource managementBartosz Golaszewski
rtc_register_device() is a managed interface but it doesn't use devres by itself - instead it marks an rtc_device as "registered" and the devres callback for devm_rtc_allocate_device() takes care of resource release. This doesn't correspond with the design behind devres where managed structures should not be aware of being managed. The correct solution here is to register a separate devres callback for unregistering the device. While at it: rename rtc_register_device() to devm_rtc_register_device() and add it to the list of managed interfaces in devres.rst. This way we can avoid any potential confusion of driver developers who may expect there to exist a corresponding unregister function.

2020-11-19mfd: cpcap: Fix interrupt regression with regmap clear_ackTony Lindgren
With commit 3a6f0fb7b8eb ("regmap: irq: Add support to clear ack registers"), the cpcap interrupts are no longer getting acked properly leading to a very unresponsive device with CPUs fully loaded spinning in the threaded IRQ handlers. To me it looks like the clear_ack commit above actually fixed a long standing bug in regmap_irq_thread() where we unconditionally acked the interrupts earlier without considering ack_invert. And the issue with cpcap started happening as we now also consider ack_invert. Tim Harvey <tharvey@gateworks.com> tried to fix this issue earlier with "[PATCH v2] regmap: irq: fix ack-invert", but the reading of the ack register was considered unnecessary for just ack_invert, and we did not have clear_ack available yet. As the cpcap irqs worked both with and without ack_invert earlier because of the unconditional ack, the problem remained hidden until now. Also, looks like the earlier v3.0.8 based Motorola Android Linux kernel does clear_ack style read-clear-write with "ireg_val & ~mreg_val" instead of just ack_invert style write. So let's switch cpcap to use clear_ack to fix the issue.

2020-11-19mfd: MFD_SL28CPLD should depend on ARCH_LAYERSCAPEGeert Uytterhoeven
Currently the Kontron sl28cpld Board Management Controller is found only on Kontron boards equipped with a Freescale Layerscape SoC. Hence add a dependency on ARCH_LAYERSCAPE, to prevent asking the user about a driver for this controller when configuring a kernel without Layerscape support.

2020-11-19mfd: at91-usart: Do not use compatible to register child devicesCodrin Ciubotariu
There are no separate serial/SPI devices under the at91-usart MFD, but actually the MFD is used as a serial or a SPI device. There are no DT sub-nodes for the MFD children, so we should use platform device API to register the drivers.

2020-11-19mfd: madera: Add special errata reset handling for cs47l15Charles Keepax
An errata exists for cs47l15 where the reset must be handled differently and removed before DCVDD is applied. A soft reset is used for situations where a reset is required to reset state. This does however, make this part unsuitable for DCVDD supplies with a rise time greater than 2mS.

2020-11-19mfd: madera: Add reset as part of resumeCharles Keepax
The DCVDD supply does not always power down when the CODEC enters suspend, for example shared regulators or always-on regulators. In these cases if a register is written back to the default value whilst the CODEC is in suspend that register will retain the previous value. As DCVDD never powered down, the register retains its old value and as the cache sync only synchronises registers that differ from the default the new value is never written out. Ensure the registers are in the expected state after suspend by always resetting the CODEC on resume. This also has the benefit of being recommended by the datasheet for DCVDD supplies that take longer than 2mS to rise.
