This reverts commit d0515205 . The input gpio driver is not ready, and it was pushed upstream in error. 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:

The standard trigger attribute 'nsamples' and the extended attribute 'ms-period' are now supported by zio-trig-timer. ms-period: is used to specify the time, in milliseconds, between trigger activations. 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:

zio invokes try_module_get() on buffer, trigger and device owners when they are in use. For devices we still have a little unsafe time. Signed-off-by:

To be more suitable for different situation, the returned value is changed from zio_obj_head to zio_object_list_item, which contains the head and other useful information. zbuf_find_by_name() and trig_find_by_name() are modified too, according to __find_by_name() Signed-off-by:
