I was just fixing your DT comments and have a small patch to set dev_ready=true. I'll send it soon. But still you need to consider that nand/omap2.c driver only supports polling way of monitoring READY/BUSY pin. That is instead of polling for status-bit | waiting for predefined delay, NAND driver now polls for READY/BUSY pin. However, actual benefit of wait-pin monitoring might be visible when READY/BUSY pin is used with interrupt. with regards, pekon -- 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
