+What: dv1394 (a.k.a. "OHCI-DV I/O support" for FireWire)
+Contact: linux1394-devel@lists.sourceforge.net
+Description:
+ New application development should use raw1394 + userspace libraries
+ instead, notably libiec61883 which is functionally equivalent.
+
+Users:
+ ffmpeg/libavformat (used by a variety of media players)
+ dvgrab v1.x (replaced by dvgrab2 on top of raw1394 and resp. libraries)
---------------------------
-What: dv1394 driver (CONFIG_IEEE1394_DV1394)
-When: June 2007
-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.
-Who: Dan Dennedy <dan@dennedy.org>, Stefan Richter <stefanr@s5r6.in-berlin.de>
-
----------------------------
-
What: Video4Linux API 1 ioctls and video_decoder.h from Video devices.
When: December 2006
Why: V4L1 AP1 was replaced by V4L2 API. during migration from 2.4 to 2.6
- Output values are writable (high=1, low=0). Some chips also have
options about how that value is driven, so that for example only one
value might be driven ... supporting "wire-OR" and similar schemes
- for the other value.
+ for the other value (notably, "open drain" signaling).
- Input values are likewise readable (1, 0). Some chips support readback
of pins configured as "output", which is very useful in such "wire-OR"
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?

Miscellaneous
-
- noreplacement Don't replace instructions with more appropriate ones
- for the CPU. This may be useful on asymmetric MP systems
