imx8mm linux kernel 4.14.98 ,kernel-4.14.98/drivers/hwmon/sht15.c

log error:

insmod sht15.ko
[ 425.787145] gpio-82 (SHT15 data): _gpiod_direction_output_raw: tried to set a GPIO tied to an IRQ as output
[ 425.796987] sht15: probe of p8-ports failed with error -5

dts:

231 pinctrl_p8_ports: p8_ports_grp {
232      fsl,pins = <
233           MX8MM_IOMUXC_NAND_WE_B_GPIO3_IO17 0x19
234           MX8MM_IOMUXC_NAND_WP_B_GPIO3_IO18 0x19
235       >;
236 };

sht15.c:

devm_request_irq(&pdev->dev, gpio_to_irq(data->pdata->gpio_data),

disable_irq_nosync(gpio_to_irq(data->pdata->gpio_data));

gpio_direction_output(data->pdata->gpio_data, 1);

dts change MX8MM_IOMUXC_NAND_WP_B_GPIO3_IO18 0x80000000 is error,imx6 3.14.28 is ok,imx6 4.9.88 is error。

The following is the Chinese translation:

--------------------------------------------------------------------------------

imx8mm 内核4.14.98Linux系统,sht15.c文件里,把GPIO设置成中断,然后失能中断,然后切换到GPIO输出,提示不行,把设备树配置成0x80000000也不行,imx6 3.14.28内核可以,imx6的4.9.88不行。

Hi igorpadykov

Thank you for your reply.

Can I change the imX8 pins? I don't think the kernel will be modified, it's just upgraded to solve some configuration problems that don't make sense。

Hi jianfeichang

 

seems this feature is not supported on last kernels as described on other forums, like:

https://github.com/raspberrypi/linux/issues/808

One can post issue on kernel mail list:

http://vger.kernel.org/vger-lists.html

 

Best regards
