* docs: driver-model: move it to the driver-api bookMauro Carvalho Chehab2019-07-151-1/+1
| | | | | | | The audience for the Kernel driver-model is clearly Kernel hackers. Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> Acked-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> # ice driver changes
* docs: driver-model: convert docs to ReST and rename to *.rstMauro Carvalho Chehab2019-06-211-1/+1
| | | | | | | | | | | | | | | | | | | Convert the various documents at the driver-model, preparing them to be part of the driver-api book. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.
