ptp: create "pins" together with the rest of attributes

2017-02-17T16:03:06+00:00

Let's switch to using device_create_with_groups(), which will allow us to create "pins" attribute group together with the rest of ptp device attributes, and before userspace gets notified about ptp device creation. Signed-off-by: Dmitry Torokhov Signed-off-by: David S. Miller

ptp: use is_visible method to hide unused attributes

2017-02-17T16:03:06+00:00

Instead of creating selected attributes after the device is created (and after userspace potentially seen uevent), lets use attribute group is_visible() method to control which attributes are shown. This will allow us to create all attributes (except "pins" group, which will be taken care of later) before userspace gets notified about new ptp class device.

ptp: use kcalloc when allocating arrays

2017-02-17T16:03:06+00:00

kcalloc is more semantically correct when allocating arrays of objects, and overflow-safe. Signed-off-by: Dmitry Torokhov Signed-off-by: David S. Miller

ptp: use permission-specific DEVICE_ATTR variants

2016-10-31T19:32:12+00:00

Use DEVICE_ATTR_RO for read only attributes. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @ro@ declarer name DEVICE_ATTR; identifier x,x_show; @@ DEVICE_ATTR(x, \(0444\|S_IRUGO\), x_show, NULL); @script:ocaml@ x << ro.x; x_show << ro.x_show; @@ if not (x^"_show" = x_show) then Coccilib.include_match false @@ declarer name DEVICE_ATTR_RO; identifier ro.x,ro.x_show; @@ - DEVICE_ATTR(x, \(0444\|S_IRUGO\), x_show, NULL); + DEVICE_ATTR_RO(x); // Signed-off-by: Julia Lawall Acked-by: Richard Cochran Signed-off-by: David S.

ptp: expose the programmable pins via sysfs

2014-03-21T18:21:14+00:00

This patch adds the sysfs hooks needed in order to get and set the programmable pin settings. Signed-off-by: Richard Cochran Signed-off-by: David S. Miller

PTP: convert class code to use dev_groups

2013-07-27T01:05:17+00:00

The dev_attrs field of struct class is going away soon, dev_groups should be used instead. This converts the ptp class code to use the correct field. Acked-by: Richard Cochran Signed-off-by: Greg Kroah-Hartman

ptp: Added a brand new class driver for ptp clocks.

2011-05-23T20:01:00+00:00

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.
