-Why: Replaced by raw1394 + userspace libraries, notably libiec61883. This
- shift of application support has been indicated on www.linux1394.org
- and developers' mailinglists for quite some time. Major applications
- have been converted, with the exception of ffmpeg and hence xine.
- Piped output of dvgrab2 is a partial equivalent to dv1394.

when the IRQ is edge-triggered.
+Emulating Open Drain Signals
+----------------------------
+Sometimes shared signals need to use "open drain" signaling, where only the
+low signal level is actually driven. (That term applies to CMOS transistors;
+"open collector" is used for TTL.) A pullup resistor causes the high signal
+level. This is sometimes called a "wire-AND"; or more practically, from the
+negative logic (low=true) perspective this is a "wire-OR".
+
+One common example of an open drain signal is a shared active-low IRQ line.
+Also, bidirectional data bus signals sometimes use open drain signals.
+
+Some GPIO controllers directly support open drain outputs; many don't. When
+you need open drain signaling but your hardware doesn't directly support it,
+there's a common idiom you can use to emulate it with any GPIO pin that can
+be used as either an input or an output:
+
+ LOW: gpio_direction_output(gpio, 0) ... this drives the signal
+ and overrides the pullup.
+
+ HIGH: gpio_direction_input(gpio) ... this turns off the output,
+ so the pullup (or some other device) controls the signal.
+
+If you are "driving" the signal high but gpio_get_value(gpio) reports a low
+value (after the appropriate rise time passes), you know some other component
+is driving the shared signal low. That's not necessarily an error. As one
+common example, that's how I2C clocks are stretched: a slave that needs a
+slower clock delays the rising edge of SCK, and the I2C master adjusts its
+signaling rate accordingly.
+
What do these conventions omit?
