ABI: sysfs-devices: add /dev ABI

2021-09-28T10:48:15Z

Changeset 23681e479129 ("[PATCH] Driver core: allow struct device to have a dev_t") added a /dev ABI for /sys/devices. Document it.

docs: ABI: stable: make files ReST compatible

2020-10-30T12:07:01Z

Several entries at the stable ABI files won't parse if we pass them directly to the ReST output. Adjust them, in order to allow adding their contents as-is at the stable ABI book.

documentation: drivers/core/of: fix name of of_node symlink

2016-08-31T13:14:44Z

commit 5590f3196b29 ("drivers/core/of: Add symlink to device-tree from devices with an OF node") added a symlink called "of_node" to sysfs however the documentation describes it as "of_path". Fix the documentation to match what the code actually does. Signed-off-by: Martin Fuzzey Acked-by: Rob Herring Signed-off-by: Greg Kroah-Hartman

drivers/core/of: Add symlink to device-tree from devices with an OF node

2015-03-25T13:56:58Z

So I've been annoyed lately with having a bunch of devices such as i2c eeproms (for use by VPDs, server world !) and other bits and pieces that I want to be able to identify from userspace, and possibly provide additional data about from FW. Basically, it boils down to correlating the sysfs device with the OF tree device node, so that user space can use device-tree info such as additional "location" or "label" (or whatever else we can come up with) propreties to identify a given device, or get some attributes of use about it, etc... Now, so far, we've done that in some subsystem in a fairly ad-hoc basis using "devspec" properties. For example, PCI creates them if it can correlate the probed device with a DT node. Some powerpc specific busses do that too. However, i2c doesn't and it would be nice to have something more generic since technically any device can have a corresponding device tree node. This patch adds an "of_node" symlink to devices that have a non-NULL dev->of_node pointer, the patch is pretty trivial and seems to work just fine for me.
