* pinctrl: Get rid of duplicate of_node assignment in the driversAndy Shevchenko2021-12-161-1/+0
| | | | | | | | | | | | GPIO library does copy the of_node from the parent device of the GPIO chip, there is no need to repeat this in the individual drivers. Remove these assignment all at once. For the details one may look into the of_gpio_dev_init() implementation.

* pinctrl: Bulk conversion to generic_handle_domain_irq()Marc Zyngier2021-08-121-3/+2
| | | | | | | | | | | Wherever possible, replace constructs that match either generic_handle_irq(irq_find_mapping()) or generic_handle_irq(irq_linear_revmap()) to a single call to generic_handle_domain_irq().

* pinctrl: actions: pinctrl-owl: Constify owl_pinctrl_ops and owl_pinmux_opsRikard Falkeborn2020-09-121-2/+2
| | | | | | | | | | | | The only usage of owl_pinctrl_ops and owl_pinmux_ops is to assign their addresses to the pctlops and the pmxops fields in the pinctrl_desc struct, which are const pointers. Make them const to allow the compiler to put them in read-only memory.

| * pinctrl: actions: fix unsigned less than zero comparisonColin Ian King2018-07-021-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The check to see if platform_get_irq failed is performed on the unsigned value of pctrl->irq[i] and the check is never true because an unsigned cannot be less than zero. Fix this by assinging the signed int ret to the return of platform_get_irq and checking ret instead.
