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 at 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 at 2 {
reg = <2>;
tpdm_mm_out_tpda9: endpoint {
remote-endpoint =
<&tpda_9_in_tpdm_mm>;
label = <&tpdm_mm>;
};
};
port at 3 {
reg = <3>;
funnel_dl_center_out_tpda_10: endpoint {
remote-endpoint =
<&tpda_10_in_funnel_dl_center>;
label = <&tpdm_lpass>;
};
};
port at 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 at 15 {
reg = <2>;
funnel_dl_center_in_funnel_dl_mm: endpoint {
slave-mode;
remote-endpoint =
<&funnel_dl_mm_out_funnel_dl_center>;
};
};
port at 16 {
reg = <3>;
funnel_dl_center_in_funnel_lpass: endpoint {

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