Hi Mathieu,

Sorry, the TPDM/TPDA related code in the device tree was omitted in this submission.
We will add them to device tree in the next version.
Paste this funnel configuration below for you review first.
funnel@6c2d000 {
compatible = "arm,coresight-dynamic-funnel", "arm,primecell";

reg = <0 0x6c2d000 0 0x1000>;
reg-names = "funnel-base";

clocks = <&aoss_qmp>;
clock-names = "apb_pclk";

out-ports {
#address-cells = <1>;
#size-cells = <0>;
port@2 {
reg = <2>;
tpdm_mm_out_tpda9: endpoint {
remote-endpoint =
<&tpda_9_in_tpdm_mm>;
label = <&tpdm_mm>;
};
};

port@3 {
reg = <3>;
funnel_dl_center_out_tpda_10: endpoint {
remote-endpoint =
<&tpda_10_in_funnel_dl_center>;
label = <&tpdm_lpass>;
};
};

port@7 {
reg = <7>;
tpdm_turing_out_tpda14: endpoint {
remote-endpoint =
<&tpda_14_in_tpdm_turing>;
label = <&tpdm_turing>;
};
};
};

in-ports {
#address-cells = <1>;
#size-cells = <0>;

port@15 {
reg = <2>;
funnel_dl_center_in_funnel_dl_mm: endpoint {
slave-mode;
remote-endpoint =
<&funnel_dl_mm_out_funnel_dl_center>;
};
};

port@16 {
reg = <3>;
funnel_dl_center_in_funnel_lpass: endpoint {
slave-mode;
remote-endpoint =
<&funnel_lpass_out_funnel_dl_center>;
};
};

port@18 {
reg = <5>;
funnel_dl_center_in_funnel_compute: endpoint {
slave-mode;
remote-endpoint =
<&funnel_compute_out_funnel_dl_center>;
};
};
};
};

Hi Mathieu,

We will add TPDM/TPDA related code to the device tree in the next verison.

Best,
