2017-02-21PM / docs: Fix structure references in device.rstRafael J. Wysocki1-34/+38
There is a better way to represent structure references than it was done in device.rst by commit 730c4c053012 (PM / sleep / docs: Convert PM notifiers document to reST), which is to use "struct name" as a link caption (e.g. :c:type:`struct device <device>`). That will cause sphinx to generate a proper reference to the data type in question (struct device in the example above) and "struct name" will work as the link in the HTML output. Fix device.rst by using that convention where applicable. Fixes: 730c4c053012 (PM / sleep / docs: Convert PM notifiers document to reST) Signed-off-by: Rafael J.

2017-02-06PM / sleep / docs: Convert PM notifiers document to reSTRafael J. Wysocki3-1/+72
Move the document describing PM notifiers (used during system sleep state transitions) to Documentation/driver-api/pm/, convert it to reST and update it to use current terminology. Also replace the remaining references to the old version of it in .txt documents with references to the new one. Signed-off-by: Rafael J.

2017-02-06PM / core / docs: Convert sleep states API document to reSTRafael J. Wysocki5-0/+763
Move the document describing the system sleep state transitions API for devices to Documentation/driver-api/pm/, convert it to reST and update it to use current terminology. Also remove the remaining reference to the old version of it from pm.h. The new document still contains references to some documents in the .txt format that will be converted later.

2017-02-01docs: Convert the regulator docbook to RSTJonathan Corbet2-0/+171
A fairly straightforward conversion to RST; the document is then added to the driver-api manual. Of course, this document has seen no substantive changes since 2008, so chances are it needs work in other areas as well.

2017-02-01docs: Convert the deviceio template to RSTJonathan Corbet2-0/+202
Convert deviceiobook.tmpl to RST and incorporate it into the driver API manual. Like the rest of our documentation, this one could use some work. There's no mention of ioremap() and friends, no mention of io_read*() and friends. But we have nice documentation for all those folks writing new drivers that do port I/O :). The :c:func: notation has been left off of all the read*/write* functions. There's no kerneldoc comments for them anyway, so those links will never be live, and writing a bunch of repetitive "read a byte from I/O memory" comments lacks appeal.

git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next Johannes Berg says: ==================== For 4.11, we seem to have more than in the past few releases: * socket owner support for connections, so when the wifi manager (e.g. wpa_supplicant) is killed, connections are torn down - wpa_supplicant is critical to managing certain operations, and can opt in to this where applicable * minstrel & minstrel_ht updates to be more efficient (time and space) * set wifi_acked/wifi_acked_valid for skb->destructor use in the kernel, which was already available to userspace * don't indicate new mesh peers that might be used if there's no room to add them * multicast-to-unicast support in mac80211, for better medium usage (since unicast frames can use *much* higher rates, by ~3 orders of magnitude) * add API to read channel (frequency) limitations from DT * add infrastructure to allow randomizing public action frames for MAC address privacy (still requires driver support) * many cleanups and small improvements/fixes across the board ==================== Signed-off-by: David S.

git://anongit.freedesktop.org/git/drm-misc into drm-next First -misc pull for 4.11: - drm_mm rework + lots of selftests (Chris Wilson) - new connector_list locking+iterators - plenty of kerneldoc updates - format handling rework from Ville - atomic helper changes from Maarten for better plane corner-case handling in drivers, plus the i915 legacy cursor patch that needs this - bridge cleanup from Laurent - plus plenty of small stuff all over - also contains a merge of the 4.10 docs tree so that we could apply the dma-buf kerneldoc patches It's a lot more than usual, but due to the merge window blackout it also covers about 4 weeks, so all in line again on a per-week basis. The more annoying part with no pull request for 4 weeks is managing cross-tree work. The -intel pull request I'll follow up with does conflict quite a bit with -misc here. Longer-term (if drm-misc keeps growing) a drm-next-queued to accept pull request for the next merge window during this time might be useful. I'd also like to backmerge -rc2+this into drm-intel next week, we have quite a pile of patches waiting for the stuff in here. * tag 'drm-misc-next-2016-12-30' of git://anongit.freedesktop.org/git/drm-misc: (126 commits) drm: Add kerneldoc markup for new @scan parameters in drm_mm drm/mm: Document locking rules drm: Use drm_mm_insert_node_in_range_generic() for everyone drm: Apply range restriction after color adjustment when allocation drm: Wrap drm_mm_node.hole_follows drm: Apply tight eviction scanning to color_adjust drm: Simplify drm_mm scan-list manipulation drm: Optimise power-of-two alignments in drm_mm_scan_add_block() drm: Compute tight evictions for drm_mm_scan drm: Fix application of color vs range restriction when scanning drm_mm drm: Unconditionally do the range check in drm_mm_scan_add_block() drm: Rename prev_node to hole in drm_mm_scan_add_block() drm: Fix O= out-of-tree builds for selftests drm: Extract struct drm_mm_scan from struct drm_mm drm: Add asserts to catch overflow in drm_mm_init() and drm_mm_init_scan() drm: Simplify drm_mm_clean() drm: Detect overflow in drm_mm_reserve_node() drm: Fix kerneldoc for drm_mm_scan_remove_block() drm: Promote drm_mm alignment to u64 drm: kselftest for drm_mm and restricted color eviction ...

2017-01-03PM / docs: Drop confusing kernel-doc references from infrastructure.rstRafael J. Wysocki1-15/+0
The references to drivers/base/power/main.c and drivers/acpi/scan.c from Documentation/driver-api/infrastructure.rst are confusing. They both cause descriptions of functions that are not relevant to device drivers at all to be generated and none of them is sufficient to cover the API in a meaningful way. Drop them for now.

2016-12-13dma-buf: Update cpu access documentationDaniel Vetter1-0/+6
- Again move the information relevant for driver writers next to the callbacks. - Put the overview and userspace interface documentation into a DOC: section within the code. - Remove the text that mmap needs to be coherent - since the DMA_BUF_IOCTL_SYNC landed that's no longer the case. But keep the text that for pte zapping exporters need to adjust the address space. - Add a FIXME that kmap and the new begin/end stuff used by the SYNC ioctl don't really mix correctly. That's something I just realized while doing this doc rework. - Augment function and structure docs like usual.
