• 85a66e550   ptp: create "pins" together with the rest of attributes ... Browse Code »

  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.

• af59e717d   ptp: use is_visible method to hide unused attributes ... Browse Code »

  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.

• 63215705a   ptp: use permission-specific DEVICE_ATTR variants ... Browse Code »

  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);

• 3499116b9   PTP: convert class code to use dev_groups ... Browse Code »

  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.

• d94ba80eb   ptp: Added a brand new class driver for ptp clocks. ... Browse Code »

  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.
