drm/nouveau/gpio: check the gpio function 16 in the power check as well (940794b3) · Commits · 戴 / test

Added GPIO is "Thermal and External Power Detect". It's uncertain if this GPIO is set on GPU initialization or only if a change is detected by the GPU at runtime. This GPIO can be found in Rankine and Curie and rarely on Tesla GPUs VBIOS. Untested, wrote according to documentation. Signed-off-by:
