2021-09-21ABI: sysfs-ptp: use wildcards on What definitionsMauro Carvalho Chehab1-15/+15
An "N" upper letter is not a wildcard, nor can easily be identified by script, specially since the USB sysfs define things like. bNumInterfaces. Use, instead, <N>, in order to let script/get_abi.pl to convert it into a Regex.

2021-07-01ptp: support ptp physical/virtual clocks conversionYangbo Lu1-0/+20
Support ptp physical/virtual clocks conversion via sysfs. There will be a new attribute n_vclocks under ptp physical clock sysfs. - In default, the value is 0 meaning only ptp physical clock is in use. - Setting the value can create corresponding number of ptp virtual clocks to use. But current physical clock is guaranteed to stay free running. - Setting the value back to 0 can delete virtual clocks and back use physical clock again. Another new attribute max_vclocks control the maximum number of ptp vclocks. Signed-off-by: Yangbo Lu <[email protected]> Signed-off-by: David S. Miller <[email protected]>

s/avaiable/available/g This fixup is already in scripts/spelling.txt. The fix in Documentation/ABI/testing/sysfs-ptp affects documentation of a /sys entry: the /sys entry itself is correct. Signed-off-by: Chris Dunlop <[email protected]> Signed-off-by: Jiri Kosina <[email protected]>
2014-03-21ptp: expose the programmable pins via sysfsRichard Cochran1-0/+20
This patch adds the sysfs hooks needed in order to get and set the programmable pin settings. Signed-off-by: Richard Cochran <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2012-09-22ptp: clarify the clock_name sysfs attributeRichard Cochran1-1/+5
There has been some confusion among PHC driver authors about the intended purpose of the clock_name attribute. This patch expands the documation in order to clarify how the clock_name field should be understood. Signed-off-by: Richard Cochran <[email protected]> Signed-off-by: David S.

2011-05-23ptp: Added a brand new class driver for ptp clocks.Richard Cochran1-0/+98
This patch adds an infrastructure for hardware clocks that implement IEEE 1588, the Precision Time Protocol (PTP). A class driver offers a registration method to particular hardware clock drivers. Each clock is presented as a standard POSIX clock. The ancillary clock features are exposed in two different ways, via the sysfs and by a character device.
