Hi, No progress on the upstream of the mmap code at the moment, sorry. The latest code is here: https://github.com/analogdevicesinc/linux/tree/xcomm_zynq/drivers/iio but probably needs some serious rework before it is ready for upstream submission. Among other things to support the multi-planar buffers the structure layout for the buffer meta data needs to be changed. - Lars -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
