* drm/nouveau/gpio: reimplement as nouveau_gpio.c, fixing a number of issuesBen Skeggs2011-12-21
| | | | | | | | | | | | | | - 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 Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
