Subject: [PATCH 11/11] ARM: dts: bcm2711: Tune DMA parameters for HDMI audio
Date: Fri, 7 May 2021 16:03:34 +0200 [thread overview]
Message-ID: <20210507140334.204865-12-maxime@cerno.tech> (raw)
In-Reply-To: <20210507140334.204865-1-maxime@cerno.tech>
From: Dom Cobley <popcornmix@gmail.com>
Enable NO_WAIT_RESP, DMA_WIDE_SOURCE, DMA_WIDE_DEST, and bump the DMA
panic and AXI priorities to avoid any DMA transfer error with HBR audio
(8 channel, 192Hz).
