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>

ADMAIF is the interface between ADMA and AHUB. Each ADMA channel
|
|
that sends/receives data to/from AHUB must interface through an
|
|
ADMAIF channel. ADMA channel sending data to AHUB pairs with ADMAIF
|
|
Tx channel and ADMA channel receiving data from AHUB pairs with
|
|
ADMAIF Rx channel.
