core: add channel template · a1219017

Federico Vaga authored 13 years ago


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

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.
