    drm/nouveau/gpio: reimplement as nouveau_gpio.c, fixing a number of issues · a0b25635
    Ben Skeggs authored
    - moves out of nouveau_bios.c and demagics the logical state definitions
    - simplifies chipset-specific driver interface
    - makes most of gpio irq handling common, will use for nv4x hpd later
    - api extended to allow both direct gpio access, and access using the
      logical function states
    - api extended to allow for future use of gpio extender chips
    - pre-nv50 was handled very badly, the main issue being that all GPIOs
      were being treated as output-only.
    - fixes nvd0 so gpio changes actually stick, magic reg needs bashing
