Subject: [PATCH 0/4] ASoC: Add Cadence I2S-SC and I2S-MC controller support
Date: Tue, 22 Sep 2026 19:21:30 +0800 [thread overview]
Message-ID: <20260922112134.4167305-1-joakim.zhang@cixtech.com> (raw)
From: Joakim Zhang <joakim.zhang@cixtech.com>
This series adds DT bindings and ASoC CPU DAI drivers for the two
Cadence I2S controllers integrated in the CIX SKY1 audio subsystem.
I2S-SC is a full-duplex stereo controller supporting standard I2S,
left/right-justified and DSP formats, mono operation mapped onto the
left audio channel, and TDM operation with up to 16 slots per frame.
I2S-MC is a multi-channel controller which moves up to 16 channels
through a configurable set of its 8 data pins, each pin carrying two
slots, and exposes a transmit DAI and a receive DAI which can act as
clock provider or consumer independently.
Both drivers register the dmaengine PCM helper, select the audio
reference clock parent for the 8 kHz or 11.025 kHz sample rate
family, keep the minimum functional-clock to bit-clock ratio
required for safe clock domain crossing, and support runtime and
system suspend/resume with regcache restore.
