[PATCH] drm/gpio/nv50: post nv92 cards have 32 interrupt lines
Since the original merge of nouveau to upstream kernel, we were assuming that
nv90 (and later) cards have 32 lines.
Based on mmio traces of the binary driver, as well as PBUS error messages
during read/write of the e070/e074 registers, we can conclude that nv92 has
only 16 lines whereas nv94 (and later) cards have 32.
