Surely this ** doesn't work ** at least against the OMAP git tree which already has: omap_cfg_reg(J25_34XX_GPIO170); gpio_request(170, "DVI_nPD"); /* REVISIT leave DVI powered down until it's needed ... */ gpio_direction_output(170, true); Label matches the DVI chip, not board schematics. Agreed, it's not a reset. I'd like to see any FB/DSS/... updates have the property that the TFP410 chip is powered down *unless* both (a) the frame buffer/DSS/... driver is active, and (b) the DVI channel is in use. So for example a kernel without FB/DSS/... configured, that DVI chip is never powered up. And when only the S-Video channel is used, DVI isn't powered up either. - Dave -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
