[PATCH 0/2] vfio: platform: Improve reset support

[Geert Uytterhoeven <geert+renesas@glider.be>]

	Hi all,

This patch series improves reset support for vfio-platform:
  - The first patch fixes a bug I ran into while working on this.
  - The second patch implements generic DT reset support, for devices
    that are connected to an SoC-internal reset controller and can be
    reset in a generic way.  This avoids having to write/change a
    vfio-specific reset driver for each and every device to be
    passed-through to a guest.

This has been tested using the R-Car Gen3 GPIO Pass-Through Prototype
posted last week: the GPIO module is reset before QEMU opens the vfio
device, and reset again after QEMU has released it, as can be witnessed
by the LEDs on the Salvator-XS board.

Thanks for your comments!

when I'm talking to journalists I just say "programmer" or something like that.
