general: rename zio_sys_operations to zio_sysfs_operations · b4fb88ba

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

new trigger "user": I/O for one-shot or streaming devices · a5d1ec81

Alessandro Rubini authored 13 years ago


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.

Introduce ZIO_PARAM_{TRIGGER,BUFFER} and use it · 1ff0b546

Alessandro Rubini authored 13 years ago


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.

zio-gpio: a analog-output channel moving gpio pins · b45266cd

Alessandro Rubini authored 13 years ago


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.

zio_channel: remove t_priv field · b200e858

Alessandro Rubini authored 13 years ago


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.

general: input and output is always cset-based · 41d776d4

Alessandro Rubini authored 13 years ago


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.
