* docs: ptp.rst: Add information about NVIDIA Mellanox devicesRahul Rameshbabu2023-06-201-0/+13
| | | | | | | | | | The mlx5_core driver has implemented ptp clock driver functionality but lacked documentation about the PTP devices. This patch adds information about the Mellanox device family.

* ptp: Clarify ptp_clock_info .adjphase expects an internal servo to be usedRahul Rameshbabu2023-06-201-0/+16
| | | | | | | | | | | | .adjphase expects a PHC to use an internal servo algorithm to correct the provided phase offset target in the callback. Implementation of the internal servo algorithm are defined by the individual devices.

* docs: driver-api: add remaining converted dirs to itMauro Carvalho Chehab2019-07-151-1/+1
| | | | | | | | | There are a number of driver-specific descriptions that contain a mix of userspace and kernelspace documentation. Just like we did with other similar subsystems, add them at the driver-api groupset, but don't move the directories. Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
* docs: ptp.txt: convert to ReST and move to driver-apiMauro Carvalho Chehab2019-06-141-0/+96
The conversion is trivial: just adjust title markups. In order to avoid conflicts, let's add an :orphan: tag to it, to be removed when this file gets added to the driver-api book.
