[PATCH v2 0/2] ASoC: add compatible for ti,pcm5242
by Christian Hewitt 23 Jun '24

23 Jun '24

Update bindings and add a driver compatible for the pcm5242 chip used on the Odroid HiFi-Shield2 i2c mezzanine board. v2 adds a compatible to the SPI variant at Mark's suggestion and fixes the binding patch title/description which I managed to fat-finger in v1.

[PATCH v3 0/2] tlv320adc3xxx: Allow MICBIAS pins to be used as GPOs
by Ricard Wanderlof 23 Jun '24

23 Jun '24

In some cases, depending on system design, the MICBIAS pins on the chip are not needed as such, but a couple of extra GPIO pins would be useful. This patch allows the MICBIAS pins to be configured in the device tree as general purpose output pins, controlled via the GPIO framework. Owing to their originally intended purpose there are some limitations: when the MICBIAS pins are deactivated, they will float, so will likely need a pulldown in many applications. When activated, they will assume the voltage specified by the micbias1-vg and micbias2-vg properties, respectively, meaning that the resulting output voltage will be 2.0 V, 2.5 V or AVDD .

[PATCH 0/8] iio: adc: dfsdm: add scaling support
by Olivier Moysan 23 Jun '24

23 Jun '24

The aim of this serie is to add scaling support to STM32 DFSDM peripheral in the analog context. The DFSDM currently operates as a consumer of IIO channels provided by a generic SD modulator. As previously discussed in RFC [1], this topology is not suitable for implementing scaling. This series brings the integration of the DFSDM driver with the new IIO backend framework [2], enabling the DFSDM IIO device to offer scaling feature based on reference voltage data obtained from the IIO SD modulator backend. This generic SD modulator backend takes the place of the former SD modulator, used with legacy implementation. The DFSDM driver has been updated to adopt the generic ADC channel binding [3]. The reasons for this include: - Reducing the use of proprietary properties - Simplifying the coexistence of legacy and new backend bindings - Prepare the support of the MDF peripheral on STM32MP25 SoC Backward compatibility is maintained through legacy support. This series extends the backend framework with the following APIs (which may need further refinement): - read_raw: This API is intented to retrieve the voltage information from the backend. It is based on IIO read_raw API, but maybe we need a more specialized API here. - iio_backend_disable / iio_backend_enable: backend enable/disable to be used for PM management - devm_iio_backend_subnode_get Intended for parsing DT subnodes to allow generic channel binding support, as generic channel DT nodes are not populated as devices. Ideally, a single API would be better, but I could not identify a suitable alternative that doesn't affect the existing API (devm_iio_backend_get).
