My previous tests were carried out on the modified RK3576 IOTEST board
DTS based on RK3576 EVB1, which includes dp-connector by default. I also
did extra verification without dp-connector, and HPD detection works
correctly in both cases.
I've taken a look at the Tiger board DT configuration. The pinctrl
settings for the eDP HPD GPIO may need adjustment:
&pinctrl {
edp0 {
edp0_hpd_l: edp0-hpd-l-pin {
rockchip,pins = <4 RK_PB5 RK_FUNC_GPIO &pcfg_pull_down>;
};
};
};
It is recommended to configure GPIO4B5 as pull-down or pll-none. Pull-up
configuration may prevent GPIO interrupts from being triggered properly,
resulting in a permanent "connected" status.
Could you help try this modification and see if it resolves the issue?
Best regards,
Damon
