Setting up any gpio-hog in the device-tree for his device would "kill the bootup completely": | [ 0.477838] msm_serial 78af000.serial: could not find pctldev for node /soc/pinctrl@1000000/serial_pinmux, deferring probe | [ 0.499828] spi_qup 78b5000.spi: could not find pctldev for node /soc/pinctrl@1000000/spi_0_pinmux, deferring probe | [ 1.298883] requesting hog GPIO enable USB2 power (chip 1000000.pinctrl, offset 58) failed, -517 | [ 1.299609] gpiochip_add_data: GPIOs 0..99 (1000000.pinctrl) failed to register | [ 1.308589] ipq4019-pinctrl 1000000.pinctrl: Failed register gpiochip | [ 1.316586] msm_serial 78af000.serial: could not find pctldev for node /soc/pinctrl@1000000/serial_pinmux, deferring probe | [ 1.322415] spi_qup 78b5000.spi: could not find pctldev for node /soc/pinctrl@1000000/spi_0_pinmux, deferri This was also verified on a RT-AC58U (IPQ4018) which would no longer boot, if a gpio-hog was specified. (Tried forcing the USB LED PIN (GPIO0) to high.). The problem is that Pinctrl+GPIO registration is currently peformed in the following order in pinctrl-msm.c: 1. pinctrl_register() 2. gpiochip_add() 3. gpiochip_add_pin_range() The actual error code -517 == -EPROBE_DEFER is coming from pinctrl_get_device_gpio_range(), which is called through: gpiochip_add of_gpiochip_add of_gpiochip_scan_gpios gpiod_hog gpiochip_request_own_desc __gpiod_request chip->request gpiochip_generic_request pinctrl_gpio_request pinctrl_get_device_gpio_range pinctrl_get_device_gpio_range() is unable to find any valid pin ranges, since nothing has been added to the pinctrldev_list yet. so the range can't be found, and the operation fails with -EPROBE_DEFER. This patch fixes the issue by adding the "gpio-ranges" property to the pinctrl device node of all upstream Qcom SoC, so the ranges are added by of_gpiochip_add_pin_range(), which is called by of_gpiochip_add() before the call to of_gpiochip_scan_gpios() happens.gpiochip_add_pin_range() is longer needed and removed (to prevent adding the same entry to the pinctrldev_list twice).
