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:

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:

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:

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. Signed-off-by:

rtc-s3c driver is modified to use devm_request_and_ioremap() (combining request_mem_region and ioremap), devm_clk_get() and devm_request_irq() APIs. Since this removes the necessity of freeing the related resources the return path is also simplified. Signed-off-by:

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: 6610e089 There 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: 4a649903 The patch makes use of the provision defined in the above patch to update the hardware status of UIE mode.

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. [afzal@ti.com: handle error path] Signed-off-by:

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, 0x95a4f1e0 Writing 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/am335x Here 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:

Hexadecimal values are current found in 2 parts. A hex constant like 0x123456abcdef is found as 0 and then x123456abcdef and later coalesced. Instead, reverse the order of the 2 searches in $Constant to find 0x first, then 0 so that the entire hex constant is found all at once. Signed-off-by:

switch default case is sometimes written as "default:;". This can cause new cases added below the default to be defective. Suggest adding a break; after empty default cases to avoid fallthrough defects. Fixed indentation in the other semicolon test above it. Suggested-by:

This function is used by sparc, powerpc tile and arm64 for compat support. The patch adds a generic implementation with a wrapper for PowerPC to do the u32->int sign extension. The reason for a single patch covering powerpc, tile, sparc and arm64 is to keep it bisectable, otherwise kernel building may fail with mismatched function declarations. Signed-off-by:
