Merge tag 'iio-for-5.10c' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

3rd set of new device support features and cleanup for IIO in the 5.10 cycle.

A late set given it seems the 5.10 cycle is going to start a bit later
than expected and quite a bit came in. Includes some late breaking
fixes that can wait for the merge window.

New device support
* ad9467
- ad9434 support including dt bindings update
- ad9265 support including dt bindings update

Yaml conversion
* amlogic,meson-saradc

Core rework (heading towards multiple buffer support)
* refactor iio_device_register_eventset
* Null-ify IIO device's event_interface during unregister.

Features
* ad7291
- convert from platform_data to devicetree including bindings doc.
* core
- Add titles to a few IIO config symbols to allow simpler out of tree
building. It does little harm so why not enable it.

Fixes
* ad7292
- Fix missing of_node_put()
* at91-sama5d2
- Fix a crash due to missordering of dma enabling as a result of recent
IIO wide rework.
* gyro-adc
- Fix missing of_node_put()
* ltc2983
- Fix missing of_node_put()
* stm32-adc
- Fix an issue with runtime autosuspend related to parent autosuspending.

Cleanups
* counter/ti-eqep
- Tidy up a , instead of ;
* buffer-dmaengine
- Drop the unmanaged allocator functions as no one is using them.
* at91-sama5d2
- devm_platform_get_and_ioremap_resouce() replacing boilerplate.
* cros_ec
- move the hw fifo attributes setup into the cros_ec core.
* gp2ap002
- comment typo
* microchip-tcb-capture:
- consitifcation
* ssp
- Use PLATFORM_DEVID_NONE instead of -1 to convey true meaning.
* stm32-dfsdm
- devm_platform_get_and_ioremap_resouce() replacing boilerplate.

iio: buffer: Kconfig: add title for IIO_TRIGGERED_BUFFER symbol

For some embedded systems, a workflow involving external kernel modules
that implement IIO devices is more practical than working with in-tree
sources.

Kconfig symbols without any titles do not show up in menuconfig, and as
such are more difficult to configure granularly, as they need to be
selected by potentially unused/un-needed drivers.

This change adds a title to the IIO_TRIGGERED_BUFFER Kconfig symbol.

ASoC: Updates for v5.3

This is a very big update, mainly thanks to Morimoto-san's refactoring
work and some fairly large new drivers.

Morimoto-san.
- Support for force disconnecting muxes from Jerome Brunet.
- New drivers for Cirrus Logic CS47L35, CS47L85 and CS47L90, Conexant
CX2072X, Realtek RT1011 and RT1308.
