3 years ago Hello, issue can be closed, I found a solution. I am added flag ESP_ACK_INTERRUPT and rebuild driver. Additional in file sdio_stub.h I have replaced strange function extern void sdmmc_ack_interrupt(struct mmc_host mmc); to dummy: void sdmmc_ack_interrupt(struct mmc_host mmc) { return; }. And after that driver run normally. Thanks.

Hello, I am try to run esp8089 chip with Linux 4.19.35 (yocto project on imx6ull controller).
My device tree looks:
&usdhc1 { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_usdhc1>; card-detect-delay = <800>; status = "okay"; wakeup-source;
esp8089: sdio_wifi@1 { vmmc-supply = <®_sd1_vmmc>; compatible = "esp,esp8089"; esp,crystal_26M_en = <2>; clock-frequency = <50000000>; clock-freq-min-max = <200000 50000000>; supports-highspeed; supports-sdio; bus-width = <4>; cd-post; pm-ignore-notify; wifi-host; non-removable; disable-wp; status = "okay"; }; };
CH_PD connected to GPIO 9 imx6ull, and I am fix schematic to pullup this pin. After powerup mmc0 device recognized like high speed SDIO card:

So, I can see than sdio device not reconnected. Maybe system configurated to scaning one time peripheral devices. Can you help me to run esp8089 driver?
Schematic and dmesg in attached.
dmesg_1.txt
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Checked CH_PD - is driven for reset and reconfigureted to input when released.
Made the EXT_RES floating (I disconnected it from the circuit).
When starting the driver, manually disconnect and reconnect the sdio-device:
echo -n "2190000.usdhc" > /sys/devices/soc0/soc/2100000.aips-bus/2190000.usdhc/driver/unbind (disconnect sdio)

and after this dummy driver go up:
