Support for ADC

by Anuj Deshpande

Hi I was looking at the Zephyr for Greybus <https://github.com/cfriedt/greybus-for-zephyr/> work, and realized that the actual spec for greybus doesn't actually have support for ADC. My usecase is to use the ADCs on an attached microcontroller as if they are native ADCs on a Linux machine. I understand this is more complicated than it looks - because unlike a GPIO, or I2C, there's no such thing as a native ADC for the Linux side of things. Have I understood that correctly? I stumbled into the IIO subsystem for such requirements where there's some analog sensor that would need to be read - but that would not work through a microcontroller like my use case. If one were to look at adding such support, what would they need? Is this something that's been discussed before? Would love to understand this a bit more, and potentially contribute.

[PATCH] greybus: use pm_runtime_resume_and_get() to replace open coding

by Tian Tao

use pm_runtime_resume_and_get() to replace pm_runtime_get_sync and pm_runtime_put_noidle. this change is just to simplify the code, no actual functional changes.

[PATCH] greybus: audio: Fix sparse warning.

by Rajat Asthana

Enforce int type on SNDRV_CTL_ELEM_IFACE_MIXER to fix sparse warning: > warning: restricted snd_ctl_elem_iface_t degrades to integer The iface field in the gb_audio_control struct is of type __u8, but the values stored in it are of type int. So on conversion they are degraded. Adding (__force int) will enforce them not to be degraded.
