Subject: [PATCH 2/7] arm64: dts: ti: k3-am62a7: Drop McASP AFIFOs
Date: Tue, 4 Jun 2024 15:11:03 +0530	[thread overview]
Message-ID: <20240604-mcasp_fifo_drop-v1-2-03ebe25f47db@ti.com> (raw)
In-Reply-To: <20240604-mcasp_fifo_drop-v1-0-03ebe25f47db@ti.com>

McASP AFIFOs are not necessary with UDMA-P/BCDMA as there is buffering
on the DMA IP. Drop these for better audio latency.

Fixes: 4a2c5dddf9e9 ("arm64: dts: ti: k3-am62a7-sk: Enable audio on AM62A")
