Andrew Turner	d729904a4f	Allow for interrupts on pl061 children ... Add enough infrastructure for interrupts on children of the pl061 GPIO controller. As gpiobus already provided these the pl061 driver also needs to pass requests up the newbus hierarchy. Currently there are no children that expect to configure interrupts, however this is expected to change to support the ACPI Event Information interface.

Andrew Turner	128e746c6a	Switch the name of the pl061 driver to gpio ... We need it to be named gpio for gpiobus to work. Sponsored by: Innovate UK	2020-09-10 09:50:43 +00:00
Andrew Turner	365ed84f28	Use the correct variable to check which interrupt mode to use ... In the PL061 driver we incorrectly used the mask rather than mode to find how to configure the interrupt. Sponsored by: Innovate UK	2020-09-10 09:37:30 +00:00
Andrew Turner	1fc1a22868	Add a GPIO driver for the Arm pl061 controller ... A PL061 is a simple 8 pin GPIO controller. This GPIO device is used to signal an internal request for shutdown on some virtual machines including Arm-based Amazon EC2 instances.
