This patch series handles AP Interrupt using the GISA facility.
The patch series is based above the GISA+GIB patch series
sent by Michael Mueller.
- We define a new VFIO ioctl to ask the vfio_ap driver to register
a interruption for the guest.
- We define the assembler code to register a GISA ba
We define two VFIO ioctl command to setup and clear
the AP Queues interrupt.
Arguments passed by the guest are:
- the apqn, AP queue number
- the Notification by address
- the identifier of the previously associated adapter

But it does describe its purpose, espec
Currently, the regulator core will take ownership of any GPIO passed
into it. Makes end driver code fairly error prone as the normal devm_
patterns of allocation don't work. Update the regulator core to only
free the GPIO if it requested it, this allows the drivers to manage the
GPIO lifetime as th
Currently, a GPIO can be requested multiple times when the
NONEXCLUSIVE flag is set, however it must still be freed a single
time. This makes client code rather complex, since multiple drivers
may request the GPIO but only a single one can free it. Rather than
manually handling this in each driver
This reverts commit 466affa06703 ("regulator: wm8994: Don't
