Subject: [PATCH v3 3/9] ASoC: mediatek: mt2701: add AFE HDMI register definitions
Date: Fri, 24 Apr 2026 03:49:06 +0100 [thread overview]
Message-ID: <2c2a2e3e5d01da4a130160f5d5ffbd2a3808fe12.1776998727.git.daniel@makrotopia.org> (raw)
In-Reply-To: <cover.1776998727.git.daniel@makrotopia.org>
Add register offsets and bit defines for the MT2701/MT7623N AFE
HDMI audio output path: the HDMI BCK divider in AUDIO_TOP_CON3,
the HDMI output memif control and descriptor registers, the 8-bit
AFE_HDMI_CONN0 interconnect, and the AFE_8CH_I2S_OUT_CON engine
that drives the HDMI TX serial link. These are a prerequisite for
adding an HDMI playback path to the mt2701 AFE driver and have no
behavioural effect on their own.
