This series improves the HPD (Hotplug Detect) interrupt handling in
the Analogix DP driver to enable reliable native HPD pin detection on
Rockchip platforms, and introduces platform-specific HPD detection
schemes with fine-grained interrupt control.
[...]
Tested on RK3576 with both native HPD pin and GPIO HPD configurations.
Native HPD pin mode:
&edp {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&edp_txm0_pins>;
};
GPIO HPD mode:
&edp {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&edp0_hpd>;
hpd-gpios = <&gpio4 RK_PC1 GPIO_ACTIVE_HIGH>;
};
&pinctrl {
edp {
edp0_hpd: edp0-hpd {
rockchip,pins = <4 RK_PC1 0 &pcfg_pull_none>;
};
};
};
Yay and thanks a lot for working on that.
If I roll my display-port carrier board back to the analogix-dp being
the endpoint, this works exactly as expected :-) .
I can plug in the display at some point after the boot and have it
detected and setup correctly. Same with unplugging it while
the system is running. The connection status is correctly reported
in sysfs.
Though there is a caveat. When the eDP is not the last part, this does not
work anymore. The detect function always returns "connected" if there is
a next bridge available.
My board [0] has a physical DP connector on it, so models it as
dp-connector, but in that case the Analogix driver always reports being
connected.

... same effect with hpd-gpios in either the edp node or dp-connector node
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
