[PATCH v4 4/4] arm64: dts: rockchip: enable HDMI RX audio capture on Orange Pi 5 Plus
From: Igor Paunovic
Date: Tue Jul 21 2026 - 02:55:08 EST
Enable the shared HDMI RX sound card and the i2s7_8ch interface it
uses. 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.

Changes in v4:
- only enable the shared hdmi_receiver_sound card and i2s7_8ch, now
that the card definition lives in rk3588-extra.dtsi (Sebastian
Reichel)
New in v3.
