-Subject: i915: Move list_count() to list.h as list_count_nodes() for broader
- use
-
-From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
-
-[ Upstream commit 4d70c74659d9746502b23d055dba03d1d28ec388 ]
-
-Some of the existing users, and definitely will be new ones, want to
-count existing nodes in the list. Provide a generic API for that by
-moving code from i915 to list.h.

-Subject: posix-clock: introduce posix_clock_context concept
-
-From: Xabier Marquiegui <reibax@gmail.com>
-
-[ Upstream commit 60c6946675fc06dd2fd2b7a4b6fd1c1f046f1056 ]
-
-Add the necessary structure to support custom private-data per
-posix-clock user.
-
-The previous implementation of posix-clock assumed all file open
-instances need access to the same clock structure on private_data.
-
-The need for individual data structures per file open instance has been
-identified when developing support for multiple timestamp event queue
-users for ptp_clock.

-Subject: ptp: support event queue reader channel masks
-
-From: Xabier Marquiegui <reibax@gmail.com>
-
-[ Upstream commit c5a445b1e9347b14752b01f1a304bd7a2f260acc ]
-
-On systems with multiple timestamp event channels, some readers might
-want to receive only a subset of those channels.
-
-Add the necessary modifications to support timestamp event channel
-filtering, including two IOCTL operations:
-
-- Clear all channels
-- Enable one channel
-
-The mask modification operations will be applied exclusively on the
-event queue assigned to the file descriptor used on the IOCTL operation,
-so the typical procedure to have a reader receiving only a subset of the
-enabled channels would be:
-
-- Open device file
-- ioctl: clear all channels
-- ioctl: enable one channel
-- start reading
-
-Calling the enable one channel ioctl more than once will result in
-multiple enabled channels.
