a9cb09b7be pinctrl: Bulk conversion to generic_handle_domain_irq() 
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().

76b7f8fae3 pinctrl: microchip-sgpio: Put fwnode in error case during ->probe() 
device_for_each_child_node() bumps a reference counting of a returned variable.
We have to balance it whenever we return to the caller.

be2dc859ab pinctrl: pinctrl-microchip-sgpio: Add irq support (for sparx5) 
This adds 'interrupt-controller' features for the signals available on
the Microchip SGPIO controller, however only for controller versions
on the Sparx5 platform (or later).

7e5ea974e6 pinctrl: pinctrl-microchip-sgpio: Add pinctrl driver for Microsemi Serial GPIO 
This adds a pinctrl driver for the Microsemi/Microchip Serial GPIO
(SGPIO) device used in various SoC's.

The driver is added as a pinctrl driver, albeit only having just GPIO
support currently. The hardware supports other functions that will be
added following.
