Add coolpi-cm5-genbook DTS patch that mirrors vendor coolpi-kernel
audio routing for the internal microphone:
routing = "MIC1", "Main Mic",
"MIC2", "Headset Mic";
Necessary-but-not-sufficient: the ES8316 RX aif_out widget power-up
chain is still broken on mainline (separate issue, not addressed
here); a future codec/audio-graph-card driver fix can complete the
capture path once the topology is correct.
Include in ampere fleet manifest.

The CoolPi CM5 GenBook has an internal microphone wired to the ES8316
|
|
codec MIC1 input. The upstream DTS only declared Mic Jack on MIC2
|
|
(headset jack), so the DAPM graph has no path between MIC1 and a
|
|
named widget — internal mic capture cannot work regardless of mixer
|
|
settings.
|
|
|
|
Vendor coolpi-kernel reference (rk3588-cpcm5-genbook.dts):
|
|
rockchip,audio-routing =
|
|
"MIC1", "Main Mic",
|
|
"MIC2", "Headset Mic";
|
|
|
|
Mirror in the upstream audio-graph-card binding:
|
|
- widgets: split Mic Jack into Main Mic (internal) + Headset Mic
|
|
(external) so each input is addressable from ALSA UCM
|
|
- routing: MIC1 <- Main Mic, MIC2 <- Headset Mic
|
|
|
|
This patch is necessary but not sufficient for working internal mic
|
|
capture: a separate issue prevents the ES8316 RX aif_out widget from
|
|
powering up via DAPM when arecord opens the capture PCM (I2S OUT stays
|
|
inactive, bias_level stays Off). That second issue is not addressed
|
|
here — this patch only fixes the static DTS topology so a future codec
|
|
or audio-graph-card driver fix can complete the chain.
