ASoC: sunxi: Add new driver for Allwinner A64 codec's analog path controls The internal codec on A64 is split into 2 parts. The analog path controls are routed through an embedded custom register bus accessed through the PRCM block. Add an ASoC component driver for it. This should be tied to the codec audio card as an auxiliary device.

ASoC: Explicitly include correct DT includes The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

ASoC: sun8i-codec: Implement jack and accessory detection Add support for the jack detection functionality in the A64 variant, which uses a pair of IRQs; and microphone accessory (button) detection, which uses an ADC with an IRQ trigger. IRQs will only be triggered if the JACKDETEN, HMICBIASEN, and MICADCEN bits are set appropriately in the analog codec component (sun50i-codec-analog), but there is no direct software dependency between the two components. Setup ADC so that it samples with period of 16ms, disable smoothing and enable MDATA threshold (should be below idle voltage/HMIC_DATA value). Also enable HMIC_N, which makes sure we get HMIC_N samples after HMIC_DATA crosses the threshold. This allows us to perform steady state detection of HMIC_DATA, by comparing current and previous ADC samples, to detect end of the transient when the user de-presses the button. Otherwise ADC could sample anywhere within the transient, and the driver may mis-issue key-press events for other buttons attached to the resistor ladder. [Ondrej: Almost complete rewrite of the patch, change to use set_jack API. Better de-bounce, fix mic button handling, better interrupt processing.] Signed-off-by: Arnaud Ferraris <arnaud.ferraris@collabora.com> [Samuel: Decouple from analog codec, fixes] Co-developed-by: Samuel Holland <samuel@sholland.org> Signed-off-by: Samuel Holland <samuel@sholland.org> Co-developed-by: Ondrej Jirman <megi@xff.cz> Signed-off-by: Ondrej Jirman <megi@xff.cz> Link: https://msgid.link/r/20240302140042.1990256-5-megi@xff.cz Signed-off-by: Mark Brown <broonie@kernel.org>

ASoC: sun50i-codec-analog: Enable DAPM for earpiece switch By including the earpiece mute switch in the DAPM graph, both the earpiece amplifier and the Mixer/DAC inputs can be powered off when the earpiece is muted. While the widget is really just a simple switch, it is represented as a "mixer with named controls" to avoid including the widget name in the kcontrol name. Otherwise, it is not possible to give the widget an accurate, descriptive name without changing the kcontrol name seen by userspace (which should be stable). The mute switch is between the source selection and the amplifier, as per the diagram in the SoC manual.

ASoC: sun8i-codec: Implement jack and accessory detection Add support for the jack detection functionality in the A64 variant, which uses a pair of IRQs; and microphone accessory (button) detection, which uses an ADC with an IRQ trigger. IRQs will only be triggered if the JACKDETEN, HMICBIASEN, and MICADCEN bits are set appropriately in the analog codec component (sun50i-codec-analog), but there is no direct software dependency between the two components. Setup ADC so that it samples with period of 16ms, disable smoothing and enable MDATA threshold (should be below idle voltage/HMIC_DATA value). Also enable HMIC_N, which makes sure we get HMIC_N samples after HMIC_DATA crosses the threshold. This allows us to perform steady state detection of HMIC_DATA, by comparing current and previous ADC samples, to detect end of the transient when the user de-presses the button. Otherwise ADC could sample anywhere within the transient, and the driver may mis-issue key-press events for other buttons attached to the resistor ladder.
