[PATCH] drm/gpio/nv50: post nv92 cards have 32 interrupt lines

2013-07-11 Thread Emil Velikov
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
