Subject: [PATCH v3 4/4] arm64: dts: rockchip: enable HDMI RX audio capture on Orange Pi 5 Plus
Date: Sat, 18 Jul 2026 10:57:28 +0200	[thread overview]
Message-ID: <20260718085728.6797-5-royalnet026@gmail.com> (raw)
In-Reply-To: <20260718085728.6797-1-royalnet026@gmail.com>

Route the HDMI receiver audio to i2s7_8ch, the receive-only I2S
interface dedicated to HDMI RX, through a simple-audio-card with the
receiver as bitclock and frame master. Together with the audio
capture support in the snps_hdmirx driver this exposes a capture-only
ALSA card fed by the HDMI input.

Tested on the Orange Pi 5 Plus with multiple HDMI sources: capture
follows the source sample rate and stays in sync via the FIFO-level
clock tracking in the driver.
