Thanks,i have previous version and imho makes more sense that other devs can test too.
Was iodomain changed?
adding switch driver should be no big part as most part is mainline.if using p5 rgmii init is ready to,imho only ethsys/mtk bindung needs to be reworked.
Send sample.
Looking forward to run opnsense on this minux MTK driver

Wow nice and I still waiting for development sample. Good luck.
have you fixed the headphone-detection? in my version this pin is always gnd/0 so microphone does not switch to the headset one
hi Frank,
please refer to the below,
rk_headset: rk-headset {
status = "okay";
compatible = "rockchip_headset";
headset_gpio = <&gpio3 RK_PC2 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
pinctrl-0 = <&hp_det>;
io-channels = <&saradc 2>; //HP_HOOK pin
};
… … &pinctrl { headphone { hp_det: hp-det { rockchip,pins = <3 RK_PC2 RK_FUNC_GPIO &pcfg_pull_up>; }; };
… …
hi Frank, Maybe you need enable internal pull-up
&pinctrl { headphone { hp_det: hp-det { rockchip,pins = <3 RK_PC2 RK_FUNC_GPIO &pcfg_pull_up>; }; };
Already tried pullup and read out gpio (without mapping to soundcard)…always 0
rockchip_headset
Is no valid upstream compatible. Downstream it is in
drivers/headset_observe/rockchip_headset_core.c:180: { .compatible = "rockchip_headset", },
this driver seems to read out gpio (looks like only as busy-indicator) then adc and then gpio again in rk_headset_irq_hook_adc.c/hook_work_callback
i’m not sure if the gpio is only some kind of hw-interrupt to trigger the adc-read, but at least for this there is no mainline driver, and porting this driver is much work for this small functionality
from hw view:
Adc works but gpio does not (alone). Have not found a way in upstream to use adc for mic switch
@zuowei8 can you explain how it should work? is the gpio a hw-interrupt to trigger the adc-read? maybe i can write a simpler driver to archive the same
have added the rk_headset driver to my 5.19-hdmi-tree, but it seems not triggering the mic-change, used same settings in dts like in bsp

i see this messages, but it seems driver still does not switch mic to headset

any idea? on plugging in/out i see headset_interrupt messages in dmesg, but evtest does not show any change…and maybe i need to map this event to also somehow in userspace

means driver recognizes the change, but mic is not switched yet to headphone…i see in driver there is some reference to an extcon_* and imho input-device should change too…currently debugging
HEADSET_OUT should set input device in headset_interrupt and !=HEADSET_OUT in hook_work_callback
inout device ist not updated because headset->hook_status is always HOOK_UP, i’m not sure whats the reasing for HOOK-STATUS, but is is set only to down in hook_work_callback which is not called if headset is removed. looks for me redundant with headset_info->headset_status = [HEADSET_IN,HEADSET_OUT]
Hi Together,
i recently ordered a BPI-R2 Pro but I cannot find the schematic/component placement anywhere. Can anyone provide it to me?
Thanks, Eric
i have the schematic (not component placement), but i’m instructed not to share it. which part do you need?
@sinovoip can you/i share it now or only parts?
