  This series introduces a new rawdevice PMD which allows
to manage userspace GPIOs and install custom GPIO interrupt
handlers which bypass kernel. This is especially useful for
applications that, besides providing standard dataplane functionality,
want to have fast and low latency access to GPIO pin state.

It'd be great to have that merged during 22.02 merge window.

Tomasz Duszynski (10):
  raw/cnxk_gpio: add GPIO driver skeleton
  raw/cnxk_gpio: support reading default queue conf
  raw/cnxk_gpio: support reading queue count
  raw/cnxk_gpio: support queue setup
  raw/cnxk_gpio: support queue release
  raw/cnxk_gpio: support enqueuing buffers
  raw/cnxk_gpio: support dequeuing buffers
  raw/cnxk_gpio: support standard GPIO operations
  raw/cnxk_gpio: support custom irq handlers
  raw/cnxk_gpio: support selftest
