2012-03-27watchdog: mpcore_wdt: Rename dev to pdev for pointing to struct platform_deviceViresh Kumar
Pointer to struct platform_device is named as dev, which makes it confusing when we write statements like dev->dev to access struct device within it. This patch renames such names to pdev. Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
2012-03-27watchdog: xen: don't clear is_active when xen_wdt_stop() failedJan Beulich
xen_wdt_release() shouldn't clear is_active even when the watchdog didn't get stopped (which by itself shouldn't happen, but let's return a proper error in this case rather than adding a BUG() upon hypercall failure).

2012-03-27watchdog: fix set_timeout operationsWim Van Sebroeck
Since we changed the behaviour of the set_timeout operation in the watchdog API, we need to change the allready converted drivers so that they update the timeout field at the end of the set_timeout operation. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
2012-03-27watchdog: watchdog_dev: Let the driver update the timeout field on ↵Hans de Goede
set_timeout success When a set_timeout operation succeeds this does not necessarily mean that the exact timeout requested has been achieved, because the watchdog does not necessarily have a 1 second resolution. So rather then have the core set the timeout member of the watchdog_device struct to the exact requested value, instead the driver should set it to the actually achieved timeout value.

git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux Pull <linux/bug.h> cleanup from Paul Gortmaker: "The changes shown here are to unify linux's BUG support under the one <linux/bug.h> file. Due to historical reasons, we have some BUG code in bug.h and some in kernel.h -- i.e. the support for BUILD_BUG in linux/kernel.h predates the addition of linux/bug.h, but old code in kernel.h wasn't moved to bug.h at that time. As a band-aid, kernel.h was including <asm/bug.h> to pseudo link them. This has caused confusion[1] and general yuck/WTF[2] reactions. Here is an example that violates the principle of least surprise: CC lib/string.o lib/string.c: In function 'strlcat': lib/string.c:225:2: error: implicit declaration of function 'BUILD_BUG_ON' make[2]: *** [lib/string.o] Error 1 $ $ grep linux/bug.h lib/string.c #include <linux/bug.h> $ We've included <linux/bug.h> for the BUG infrastructure and yet we still get a compile fail! [We've not kernel.h for BUILD_BUG_ON.] Ugh - very confusing for someone who is new to kernel development. With the above in mind, the goals of this changeset are: 1) find and fix any include/*.h files that were relying on the implicit presence of BUG code. 2) find and fix any C files that were consuming kernel.h and hence relying on implicitly getting some/all BUG code. 3) Move the BUG related code living in kernel.h to <linux/bug.h> 4) remove the asm/bug.h from kernel.h to finally break the chain. During development, the order was more like 3-4, build-test, 1-2. But to ensure that git history for bisect doesn't get needless build failures introduced, the commits have been reorderd to fix the problem areas in advance.

2012-03-23rtc: ds1307: refactor chip_desc tableWolfram Sang
The chip_desc table is suboptimal. Currently it requires an entry for every new chip type, even if it is empty. This has already been forgotten for the ds1388. Refactor the code, so new entries are only needed, when they chip type really needs a (non-empty) description. Also make the table visually more appealing.

2012-03-23drivers/rtc: remove IRQF_DISABLEDYong Zhang
Since commit e58aa3d2d0cc ("genirq: run irq handlers with interrupts disabled") we run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled - see commit b738a50a2026 ("genirq: warn when handler enables interrupts"). So now this flag is a NOOP and can be removed.

2012-03-23drivers/rtc/rtc-twl.c: return correct RTC event from ISRVenu Byravarasu
Following changes are made as part of this change: 1. As TWL RTC supports periodic interrupt, the correct event should be RTC_PF instead of RTC_UF. 2. No need to initialize variable "events" to 0 & then OR it with the event values. Hence fixing it.

2012-03-23drivers/rtc/rtc-twl.c: simplify RTC interrupt clearingVenu Byravarasu
For clearing RTC interrupt, programming ALARM bit only is sufficient, as all other bits are any way not affected by writing 0 to them. Hence removed unwanted OR operation.

2012-03-23drivers/rtc/rtc-twl.c: enable RTC irrespective of its prior stateVenu Byravarasu
As part of probe, before enabling RTC, RTC_CTRL register is read to check if it is already running. If RTC is used by kernel alone, then this read is not required. Even if RTC was enabled already by boot loader, setting STOP_RTC bit again should not harm. Hence removed unwanted read operation.

2012-03-23drivers/rtc/rtc-twl.c: optimize IRQ bit accessVenu Byravarasu
As the TWL RTC driver has a cached copy of enabled RTC interrupt bits in variable rtc_irq_bits, that can be checked before really setting or masking any of the interrupt bits.
