2021-10-25pinctrl: microchip sgpio: use reset driverHoratiu Vultur1-0/+7
On lan966x platform when the switch gets reseted then also the sgpio gets reseted. The fix for this is to extend also the sgpio driver to call the reset driver which will be reseted only once by the first driver that is probed.

2021-08-12pinctrl: Bulk conversion to generic_handle_domain_irq()Marc Zyngier1-1/+1
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().

2021-06-18pinctrl: microchip-sgpio: Put fwnode in error case during ->probe()Andy Shevchenko1-1/+3
device_for_each_child_node() bumps a reference counting of a returned variable. We have to balance it whenever we return to the caller.
