* amdgpio: Mask and service interruptsAymeric Wibo2025-08-252-23/+122
| | | | | | | | | | | Mask all interrupts coming from the AMD GPIO controller and service any potential interrupts. Unserviced interrupts can block entry to S0i3 on certain AMD CPUs.

* gpio: remove gpiobus_attach_busAhmad Khalifa2025-08-131-1/+2
| | | | | | | | | | | | Since gpiobus_attach_bus can attach the gpiobus child along with its children in the same bus pass, the parent controller's reference to gpiobus might not be set by the time the children need it. Instead, drivers should use gpiobus_add_bus and explicitly call bus_attach_children.

* amdgpio: fix reading status of input pinsAndriy Gapon2019-05-241-4/+11
