H A D | tegra210_dmic.h | 8c8ff982e9e2b2eb9255fc393f938915b0ddc127 Sun Jul 19 07:01:22 CEST 2020 Sameer Pujar <spujar@nvidia.com> ASoC: tegra: Add Tegra210 based DMIC driver
The Digital MIC (DMIC) Controller is used to interface with Pulse Density Modulation (PDM) input devices. The DMIC controller implements a converter to convert PDM signals to Pulse Code Modulation (PCM) signals. From signal flow perspective, the DMIC can be viewed as a PDM receiver.
This patch registers DMIC component with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes DMIC interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow to build the driver. The DMIC devices can be enabled in the DT via "nvidia,tegra210-dmic" compatible string. This driver can be used for Tegra186 and Tegra194 chips as well.
