Merge tag 'drivers-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC driver changes from Olof Johansson:
 "A handful of driver-related changes.  We've had a bunch of them going
  in through other branches as well, so it's only a part of what we
  really have this release.

  Larger pieces are:

   - Removal of a now unused PWM driver for atmel
     [ This includes AVR32 changes that have been appropriately acked ]
   - Performance counter support for the arm CCN interconnect
   - OMAP mailbox driver cleanups and consolidation
   - PCI and SATA PHY drivers for SPEAr 13xx platforms
   - Redefinition (with backwards compatibility!) of PCI DT bindings for
     Tegra to better model regulators/power"

Note: this merge also fixes up the semantic conflict with the new
calling convention for devm_phy_create(), see commit f0ed817638 ("phy:
core: Let node ptr of PHY point to PHY and not of PHY provider") that
came in through Greg's USB tree.

Semantic merge patch by Stephen Rothwell <sfr@canb.auug.org.au> through
the next tree.

ARM Cache Coherent Network
==========================
CCN-504 is a ring-bus interconnect consisting of 11 crosspoints
(XPs), with each crosspoint supporting up to two device ports,
so nodes (devices) 0 and 1 are connected to crosspoint 0,
nodes 2 and 3 to crosspoint 1 etc.
PMU (perf) driver
-----------------
The CCN driver registers a perf PMU driver, which provides
description of available events and configuration options
in sysfs, see /sys/bus/event_source/devices/ccn*.
The "format" directory describes format of the config, config1
and config2 fields of the perf_event_attr structure. The "events"
directory provides configuration templates for all documented
events, that can be used with perf tool. For example "xp_valid_flit"
is an equivalent of "type=0x8,event=0x4". Other parameters must be
explicitly specified. For events originating from device, "node"
defines its index. All crosspoint events require "xp" (index),
"port" (device port number) and "vc" (virtual channel ID) and
"dir" (direction). Watchpoints (special "event" value 0xfe) also
require comparator values ("cmp_l" and "cmp_h") and "mask", being
index of the comparator mask.
Masks are defined separately from the event description
(due to limited number of the config values) in the "cmp_mask"
directory, with first 8 configurable by user and additional
4 hardcoded for the most frequent use cases.
Cycle counter is described by a "type" value 0xff and does
not require any other settings.
Example of perf tool use:
/ # perf list | grep ccn
ccn/cycles/ [Kernel PMU event]
<...>
ccn/xp_valid_flit/ [Kernel PMU event]
<...>
/ # perf stat -C 0 -e ccn/cycles/,ccn/xp_valid_flit,xp=1,port=0,vc=1,dir=1/ \
sleep 1
The driver does not support sampling, therefore "perf record" will
not work. Also notice that only single cpu is being selected
("-C 0") - this is because perf framework does not support
"non-CPU related" counters (yet?) so system-wide session ("-a")
would try (and in most cases fail) to set up the same event
per each CPU.
