[PATCH v4 00/12] ad_sigma_delta: convert all drivers to device-managed

From: Alexandru Ardelean
Date: Thu May 13 2021 - 08:08:52 EST


Well, for lack of a better title that's what this series does.
It merges Jonathan's patches from:
* https://lore.kernel.org/linux-iio/20210508182319.488551-1-jic23@xxxxxxxxxx/
Patch 3/3 was a polished a bit with my comments from that review and also
to use the devm_ad_sd_setup_buffer_and_trigger() function.
* https://lore.kernel.org/linux-iio/20210509114118.660422-1-jic23@xxxxxxxxxx/
Added only to base the conversion to devm_

The AD Sigma Delta family of ADC drivers share a lot of the logic in the
ad_sigma_delta lib-driver.

This set introduces a devm_ad_sd_setup_buffer_and_trigger() call, which
aims to replace the 'ad_sd_{setup,cleanup}_buffer_and_trigger()' pair.

This helps with converting the AD7780, AD7791, AD7793 and AD7192
drivers use be fully converted to device-managed functions.

Changelog v3 -> v4:
* https://lore.kernel.org/linux-iio/20210512174914.10549-1-aardelean@xxxxxxxxxxx/
* patch 'iio: adc: ad7192: handle zero Avdd regulator value'
is now 'iio: adc: ad7192: handle regulator voltage error first'
- now checking the regulator_voltage() return first for an error

Changelog v2 -> v3:
* https://lore.kernel.org/linux-iio/20210511071831.576145-1-aardelean@xxxxxxxxxxx/
* patch 'iio: adc: ad7192: handle zero Avdd regulator value as error'
is now 'iio: adc: ad7192: handle zero Avdd regulator value'
essentially just doing a simple 'if (voltage_uv >= 0)' check now

Changelog v1 -> v2:
* https://lore.kernel.org/linux-iio/20210510125523.1271237-1-aardelean@xxxxxxxxxxx/
* add my S-o-b tags on all patches; with @deviqon.com email
- Note: I'm a little unsure about the correctness of these tags; there
are a few mixed-in, with Reviewed-by & Signed-off-by; I'm fine if
Jonathan tweaks these as needed;
* added patch 'iio: adc: ad7192: handle zero Avdd regulator value as error'
* all Fixes patches should be now at the beginning of the series

Alexandru Ardelean (8):
iio: adc: ad7192: handle regulator voltage error first
iio: adc: ad_sigma_delta: introduct
devm_ad_sd_setup_buffer_and_trigger()
iio: adc: ad7793: convert to device-managed functions
iio: adc: ad7791: convert to device-managed functions
iio: adc: ad7780: convert to device-managed functions
iio: adc: ad7192: use devm_clk_get_optional() for mclk

ad_sd_{setup,cleanup}_buffer_and_trigger()

Jonathan Cameron (4):
iio: adc: ad7124: Fix missbalanced regulator enable / disable on
error.
iio: adc: ad7124: Fix potential overflow due to non sequential channel
numbers
iio: adc: ad7192: Avoid disabling a clock that was never enabled.
iio: adc: ad7124: Use devm_ managed calls for all of probe() + drop
remove()
