As Bruce Fields pointed out, kstrto* is currently lacking kerneldoc
comments. This patch adds kerneldoc comments to common variants of
kstrto*: kstrto(u)l, kstrto(u)ll and kstrto(u)int.Signed-off-by: Eldad Zack

Option parsing code expects an unsigned integer for the codepage option,
but prefixes and stores this option with "cp" before passing to
load_nls(). This makes the displayed option in /proc an invalid one.
Strip the prefix when printing so that the displayed option is valid for
reuse.Signed-off-by: Dave Reisner

parse_options() is supposed to return value < 0 on error however we
returned 0 (success) in a lot of cases. This actually was not a problem
in practice because match_token() used by parse_options() is clever and
catches most of the problems for us.Signed-off-by: Jan Kara

So far FAT either offsets time stamps by sys_tz.minuteswest or leaves them
as they are (when tz=UTC mount option is used). However in some cases it
is useful if one can specify time stamp offset on his own (e.g. when time
zone of the camera connected is different from time zone of the computer,
or when HW clock is in UTC and thus sys_tz.minuteswest == 0).So provide a mount option time_offset= which allows user to specify offset
in minutes that should be applied to time stamps on the filesystem.akpm: this code would work incorrectly when used via `mount -o remount',
because cached inodes would not be updated. But fatfs's fat_remount() is
basically a no-op anyway.Signed-off-by: Jan Kara

Enabling RTC HW block depends on the default value of TPS65910 register.
In some mode, RTC block is disabled by default.(eg. AM3517 Craneboard) In
this case, RTC_PWDN(RTC power down) bit should be cleared to enable the
RTC HW block.This patch also works in case that RTC block is active by default, because
there is no side effect even if the bit is updated again.Tested on AM3517 Craneboard.

rtc-s3c driver is modified to use devm_request_and_ioremap() (combining
request_mem_region and ioremap), devm_clk_get() and devm_request_irq()

The applications can set the RTC hardware to trigger interrupts in one
of three modes:
* AIE: Alarm interrupt
* UIE: Update interrupt (ie: once per second)
* PIE: Periodic interrupt (sub-second irqs)The above defined 3 modes are to be supported in the RTC HW in form of
interrupts. The SPEAr RTC hardware does not support the later two modes.There have been refinements in the RTC core in mainline related to
use of timer queue infrastructure to manage events in RTC. Please refer
the below mentioned patch for details:
* RTC: Rework RTC code to use timerqueue for events
* SHA ID: 6610e0893b8bc6f59b14fed7f089c5997f035f88There have been provisions added to support hardware that do not have
support the UIE mode. Please refer the following patch.
* rtc: Provide flag for rtc devices that don't support UIE
* SHA ID: 4a649903f91232d02284d53724b0a45728111767The patch makes use of the provision defined in the above patch to
update the hardware status of UIE mode.Signed-off-by: Deepak Sikri

OMAP1 RTC driver is used in multiple devices like, OMAPL138 and AM33XX.
Driver currently doesn't handle any clocks, which may be right for OMAP1
architecture but in case of AM33XX, the clock/module needs to be enabled
in order to access the registers.So convert this driver to runtime pm, which internally handles rest.

OMAP RTC IP can have kicker feature. This prevents spurious writes to
register. To write to registers kicker lock has to be released.
Procedure to do it as follows,1. write to kick0 register, 0x83e70b13
2. write to kick1 register, 0x95a4f1e0Writing value other than 0x83e70b13 to kick0 enables write locking, more
details about kicker mechanism can be found in section 20.3.3.5.3 of
AM335X TRM @www.ti.com/am335xHere id table information is added and is used to distinguish those that
require kicker handling and the ones that doesn't need it. There are more
features in the newer IP's compared to legacy ones other than kicker,
which driver currently doesn't handle, supporting additional features
would be easier with the addition of id table.Older IP (of OMAP1) doesn't have revision register as per TRM, so revision
register can't be relied always to find features, hence id table is being
used.While at it, replace __raw_writeb/__raw_readb with writeb/readb; this
driver is used on ARMv7 (AM335X SoC)Signed-off-by: Afzal Mohammed
