Subject: [PATCH 05/13] ASoC: amd: add acp6.2 pdm platform driver
Date: Fri, 12 Aug 2022 17:37:23 +0530 [thread overview]
Message-ID: <20220812120731.788052-6-Syed.SabaKareem@amd.com> (raw)
In-Reply-To: <20220812120731.788052-1-Syed.SabaKareem@amd.com>
PDM platform driver binds to the platform device created by
ACP6.2 PCI device. PDM driver registers ALSA DMA and CPU DAI
components with ASoC framework.
