Please excuse me, I think I missed those on the previous run.
adsp_dtb.mbn
Currently, waht we have released is adsp_dtbs.elf. If we modify it to
adsp_dtb.mbn, it may cause the ADSP functionality can not boot normally.

cdsp_dtb.mbn
CDSP also as above ADSP.

s/dsi/panel[-_]reset/
I will update this (like: "dsi_active" to "panel_resest_active") as your
recommendation.
+
+ dsi_suspend: dsi-suspend-state {
+ pins = "gpio133";
+ function = "gpio";
+ drive-strength = <2>;
+ bias-pull-down;
+ };
This also do update as "s/dsi/panel[-_]reset/".
+
+ te_active: te-active-state {
+ pins = "gpio86";
+ function = "mdp_vsync";
+ drive-strength = <2>;
+ bias-pull-down;
+ };
+
+ te_suspend: te-suspend-state {
+ pins = "gpio86";
+ function = "mdp_vsync";
+ drive-strength = <2>;
+ bias-pull-down;
+ };
What is the difference between these two?
TE pin needs to be pulled down for both active and suspend states. There
is no difference.
