Luis de Bethencourt 11674239f9 befs: fix comment style
The description of befs_load_sb was confusing the kernel-doc system since,
because it starts with /**, it thinks it will document the function with
kernel-doc formatting. Which it isn't.

Fix other comment style issues in the file while we are at it.

Luis de Bethencourt bbe1bd0b6b befs: add check for ag_shift in superblock
ag_shift and blocks_per_ag contain the same information in different ways,
same as block_shift and block_size do. It is worth checking this two are
consistent, but since blocks_per_ag isn't documented as mandatory to use
some implementations of befs don't enforce this, so making it non-fatal if
they don't match and just having it as a warning.

befs_error() is used in potential errors that could happen in befs to
provide informational log messages. befs_debug() is silent when
CONFIG_BEFS_DEBUG=no, and very verbose when switched on, which is why it is
used for general debugging but not for errors.

expected pattern. To make sure we have consistent information in the logs.

Vladimir Zapolskiy 39487f6688 watchdog: imx2_wdt: add pretimeout function support
The change adds watchdog pretimeout notification handling to imx2_wdt
driver, if device data contains information about a valid interrupt.

It is unlikely but still possible (e.g. through a software limitation)
that only a subset of watchdogs on SoC has interrupt lines, hence
functionally the devices from these two groups have different
capabilities, and this is reflected in different watchdog_info
structs assigned to the devices.

Vladimir Zapolskiy 53f96cee1a watchdog: pretimeout: add option to select a pretimeout governor in runtime
The change converts watchdog device attribute "pretimeout_governor" from
read-only to read-write type to allow users to select a desirable
watchdog pretimeout governor in runtime, e.g.

  % echo -n panic > /sys/..../watchdog/watchdog0/pretimeout

To get this working a list of registered pretimeout governors is created
and a new helper function watchdog_pretimeout_governor_set() is exported
to watchdog_dev.c.

If a selected governor is gone, a watchdog device pretimeout notification
is delegated to a default built-in pretimeout governor.

The change adds panic watchdog pretimeout governor, on watchdog
pretimeout event the kernel shall panic. In general watchdog
pretimeout event means that something essentially bad is going on the
system, for example a process scheduler stalls or watchdog feeder is
killed due to OOM, so printing out information attendant to panic and
before likely unavoidable reboot caused by a watchdog may help to
determine a root cause of the issue.

The change adds noop watchdog pretimeout governor, only an

watchdog triggers a pretimeout event.

While introducing the first pretimeout governor the selected design
assumes that the default pretimeout governor is selected by its name
and it is always built-in, thus the default pretimeout governor can
not be unregistered and the correspondent check can be removed from
the watchdog_unregister_governor() function.

Vladimir Zapolskiy ff84136cb6 watchdog: add watchdog pretimeout governor framework
The change adds a simple watchdog pretimeout framework infrastructure,
its purpose is to allow users to select a desired handling of watchdog
pretimeout events, which may be generated by some watchdog devices.

A user selects a default watchdog pretimeout governor during
compilation stage.

Watchdogs with WDIOF_PRETIMEOUT capability now have one more device
attribute in sysfs, pretimeout_governor attribute is intended to display
the selected watchdog pretimeout governor.

The framework has no impact at runtime on watchdog devices with no
WDIOF_PRETIMEOUT capability set.

   merged for v4.9 through the clk tree.

   clk drivers and the dts file updates must come after that.
   This includes the newly added Nextthing GR8 platform, which is
   derived from sun5i/A13.

Linus Torvalds a439f8f287 ARM: 64-bit DT updates for v4.8
The 64-bit DT changes are surprisingly small this time, we only add two
 SoC platforms: the ZTE ZX296718 Set-top-box SoC and the SocioNext
 UniPhier LD11 TV SoC, each with their reference boards.
 
 There are three new machines added for existing SoC platforms:
 
 - The Marvell Armada 8040 development board is an impressive quad-core
   Cortex-A72 machine with three 10gbit ethernet interfaces
 
 - Qualcomms DragonBoard 820c single-board computer is their current
   high-end phone platform in the 96boards form factor
 
 - Rockchip: Tronsmart Orion r86 set-top-box is a popular mid-range
   Android box based on the 8-core rk3368 SoC.

Linus Torvalds 00e729c933 ARM: DT updates for v4.9
These are as usual a very large number of mostly boring updates to
 enable devices in existing machines, or to fix minor bugs.  Notably,
 an ongoing treewide effort to fix warnings caused by an update to the
 device tree compiler. These are enabled with "make W=1" at the moment
 but can hopefully become the default once all issues have been addressed.
 
 No new SoC platform is added this time around (Armada 395 and Orion
 mv88f5181 are slight variations of existing ones), but a significant
 number of new dts files are added, which I list by platform:
 
 - Allwinner: Empire Electronix M712 and iNet d978 Rev2 tablets;
 	Orange Pi PC Plus, Orange Pi 2, Orange Pi Plus 2E,
 	Orange Pi Lite, Olimex A33-Olinuxino, and Nano Pi Neo
 	single-board computers
 
 - ARM Realview: all supported machines (ported from board files)
 
 - Broadcom: BCM958525er, BCM958522er, BCM988312hr, BCM958623hr and
 	BCM958622hr reference boards for Northstar platform;
 	Raspberry Pi Zero single-board computer
 
 - Marvell EBU: Netgear WNR854T router (ported from board file);
 	Armada 395 SoC platform and GP board
 	Armada 390 DB development board

 	Gateworks Ventana GW553x single-board computer,
 	Technologic Systems TS-4900 and
 	Engicam IMX6UL GEA M6UL computer-on-module,

Linus Torvalds 6afd563d4b ARM: SoC driver updates for v4.9
Driver updates for ARM SoCs, including a couple of newly added drivers:
 
 - The Qualcomm external bus interface 2 (EBI2), used in some of their
   mobile phone chips for connecting flash memory, LCD displays or
   other peripherals
 
 - Secure monitor firmware for Amlogic SoCs, and an NVMEM driver for the
   EFUSE based on that firmware interface.
 
 - Perf support for the AppliedMicro X-Gene performance monitor unit
 
 - Reset driver for STMicroelectronics STM32
 
 - Reset driver for SocioNext UniPhier SoCs
 
 Aside from these, there are minor updates to SoC-specific bus,
 clocksource, firmware, pinctrl, reset, rtc and pmic drivers.
