From 16e1bcc2caf446fa3e1daa040b59fd6f6272a766 Mon Sep 17 00:00:00 2001 From: Sameer Pujar Date: Sun, 19 Jul 2020 10:31:24 +0530 Subject: ASoC: tegra: Add Tegra210 based AHUB driver The Audio Hub (AHUB) comprises a collection of hardware accelerators for audio pre/post-processing and a programmable full crossbar (XBAR) for routing audio data across these accelerators in time and in parallel. AHUB supports multiple interfaces to I2S, DSPK, DMIC etc., XBAR is a switch used to configure or modify audio routing between HW accelerators present inside AHUB. This patch registers AHUB component with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes AHUB interfaces, which can be used to connect different components in the ASoC layer. Currently the driver takes care of XBAR programming to allow audio data flow through various clients of the AHUB. Makefile and Kconfig support is added to allow to build the driver. The AHUB component can be enabled in the DT via below compatible bindings. - "nvidia,tegra210-ahub" for Tegra210 - "nvidia,tegra186-ahub" for Tegra186 and Tegra194 Signed-off-by: Sameer Pujar Link: https://lore.kernel.org/r/1595134890-16470-6-git-send-email-spujar@nvidia.com Signed-off-by: Mark Brown --- sound/soc/tegra/Kconfig | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'sound/soc/tegra/Kconfig') diff --git a/sound/soc/tegra/Kconfig b/sound/soc/tegra/Kconfig index 52ec1add6952..9028e5fde3dc 100644 --- a/sound/soc/tegra/Kconfig +++ b/sound/soc/tegra/Kconfig @@ -62,6 +62,16 @@ config SND_SOC_TEGRA30_I2S Tegra30 I2S interface.
