zio_cset interface modified. You can define a channel template to apply to all new allocated channels. This replaces the sysfs attribute channel template which is not enough. Channel template includes also the sysfs attributes to apply on each channel Signed-off-by:

This is a general change that affects triggers and buffers as well. It introduces incompatibilities but the old name was actually a bug. Signed-off-by:

The user trigger is driven by read and write. It can support one-shot devices (those that produce or consume data only when user-space read or writes) and streaming device, with their own internal timings. It is, in some way, a transparent trigger, connecting buffer and device directly. Signed-off-by:

This introduces ZIO_PARAM_TRIGGER(_name) and ZIO_PARAM_BUFFER(_name) and uses them in zio-zero. We'd love most software-driven devices to use the buffer= and trigger= parameters to override the default, thus the centralized macros. Signed-off-by:

The buffer was calling trig->pull_block even for output transfers. Bug exposed by zio-trig-user.c, yet to be committed. Signed-off-by:

This is a working implementation of an output driver. For simplicity it only registers one "analog" channel. I'm using ti with 6 leds and the timer trigger. It needs a cset with channels for each bit (so-called "digital"), support for more-than-8-bits and input gpio pins. Signed-off-by:

The field was used by the output path, but now we have active_block, so output drivers should use that field instead. We may need a trigger-private field anyways, but by now we'd better find misuses. Signed-off-by:

Even if checkpatch suggests kstrtol, it is not available in 2.6.38 and later ones, so I'm sticking with the previous function for now Signed-off-by:

This patch does the following: - it adds a new header for sysfs - it changes zio-sys.c to support per-instance trig/buf attributes - it renames some functions - is simplifies sysfs handling Signed-off-by:

This changes some method and stuff, in order to make all input and output be cset-based. This solves a number of issues with the previous setup. Thus, even drivers must be made differentlym abd this fixes zio-zero accordingly. As a side effect, we have a data_done method in trigger ops, so the device can tell when it is done. And the fire_trigger returns void, since it cannot wait for stuff to be done. See documentation for details. Signed-off-by:
