overlays: rt5616: Add RT5616 audio codec overlay - #7574
Merged
Conversation
Add an overlay for the Realtek RT5616 I2S audio codec: - rt5616-mclk: 12.288 MHz fixed clock feeding the codec MCLK pin - rt5616@1b: codec on I2C1 at 0x1b with the mclk clock - simple-audio-card: I2S link to the I2S consumer controller (GPIO 18-21) with mclk-fs = 256 for 48 kHz operation The codec is the clock master (bitclock/frame master); the RP1 I2S consumer block only supports slave mode, so the bitclock-master and frame-master properties point at the codec side. The alsaname parameter overrides the ALSA card name. Tested on Raspberry Pi 5 (EDATEC IPC3020) with: dtoverlay=rt5616 Signed-off-by: zjzhao <zjzhao@edatec.cn>
