This patch adds YAML schema for DT binding of AHUB and few of its following components. These devices will be registered as ASoC components and binding will be used on Tegra210 and later chips. * ADMAIF * I2S * DMIC * DSPK DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=nvidia.com; s=n1; t=1595134894; bh=DX96zRQRNplPikN828HbAfbjGumAn9IgtktrsenKjgk=; h=X-PGP-Universal:From:To:CC:Subject:Date:Message-ID:X-Mailer: In-Reply-To:References:X-NVConfidentiality:MIME-Version: Content-Type; b=IhfGFjMxsnRHso1Ku2GEGC+mtLCy3AbRKPfgTS56XGqEWquUr/1s8n9tFpriqF7a+ tJGrTN9mKhRQGrwdey/AHsMY4Tbm4fKEWxIASgAV/lFPCfgP3BnVjEdHclc7FdBaB0 Qvd3zs8HFsgoIzksLrtHNMrUepkeZajn0/XnC7nghGDRim4+6Hauupr5kj/KVlihsS KS1YQ2Zz9TZzLaC5QXALiHj3ATLvBFrmIf6Vj19q7hePt0menTZVzQNy+y3h4xZfLH +OvBCsLgHGGhq+iM9rm64D+S5Op2vCslwq3Q/42TnYZ0vDbD7aA9nTAQzfYeI6HK6b vi7eYbryzCTSg== Signed-off-by: Sameer Pujar <spujar@nvidia.com> Link: https://lore.kernel.org/r/1595134890-16470-2-git-send-email-spujar@nvidia.com Signed-off-by: Mark Brown <broonie@kernel.org>

title: Tegra210 DMIC Controller Device Tree Bindings
|
|
|
|
description: |
|
|
The Digital MIC (DMIC) Controller is used to interface with Pulse
|
|
Density Modulation (PDM) input devices. It converts PDM signals to
|
|
Pulse Coded Modulation (PCM) signals. DMIC can be viewed as a PDM
|
|
receiver.

The name can be "DMIC1" or "DMIC2" ... "DMICx", where x depends

on the maximum available instances on a Tegra SoC.
