* mfd: AB3100 register access change to abx500 APIMattias Wallin2010-05-27
| | | | | | | | | | | | | | | | The interface for the AB3100 is changed to make way for the ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson Analog Baseband chips. The register access functions are moved out to a separate struct abx500_ops. In this way the interface is moved from the implementation and the sub functionality drivers can keep their interface intact when chip infrastructure and communication mechanisms changes. We also define the AB3550 device IDs and the AB3550 platform data struct and convert the catenated 32bit event to an array of 3 x 8bits.

| | | | | | | | | | | | | | Now that the WM831x core uses genirq for the IRQ controller there is no need to use the WM831x-specific wrappers to request interrupts so convert to use genirq directly.

* rtc-cmos: do dev_set_drvdata() earlier in the initializationDan Carpenter2010-05-25
| | | | | | | | | | | | | | | | | | | | | | | | | | The bug is an oops when dev_get_drvdata() returned null in cmos_update_irq_enable(). The call tree looks like this: rtc_dev_ioctl() => rtc_update_irq_enable() => cmos_update_irq_enable() It's caused by a race condition in the module initialization. It is rtc_device_register() which makes the ioctl operations live so I moved the call to dev_set_drvdata() before the call to rtc_device_register().

* rtc-ds1302: add some abstraction for new platform supportMarc Zyngier2010-05-25
| | | | | | | | | | | | | | | | | | The current ds1302 driver (or at least the one that lives in /drivers/rtc) seems to be designed for memory mapped devices only. This make it quite hard to add support for GPIO-based implementations (as this is the case for the upcoming Arcom Vulcan). This patch moves the direct register access to inline functions with explicit names. Still not as good as a proper platform driver, but at least neater.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rtc-omap driver currently hardcodes the RTC wakeup capability to be "not capable". While this seems to be true for existing OMAP1 boards which are not wired for this, the DA850/OMAP-L138 SoC, the RTC can always be wake up source from its "deep sleep" mode. This patch lets the wakeup capability to be set from platform data and does not override the setting from the driver. For DA850/OMAP-L138, this is done from arch/arm/mach-davinci/devices-da8xx.c:da8xx_register_rtc() Note that this patch does not change the behavior on any existing OMAP1 board since the platform device registration sets the wakeup capability to 0 by default.

* | include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

For I2C devices there is I2C_CLIENT_WAKE flag exists that we can pass via board info, and if set, I2C core will initialize wakeup capability. For SPI devices there is no such flag at all. I believe that it's not platform code responsibility to allow or disallow wakeups, instead, drivers themselves should set the capability if a device can trigger wakeups. That's what drivers/base/power/sysfs.c says: * It is the responsibility of device drivers to enable (or disable) * wakeup signaling as part of changing device power states, respecting * the policy choices provided through the driver model. I2C and SPI RTC devices send wakeup events via interrupt lines, so we should set the wakeup capability if IRQ is routed. Ideally we should also check irq for wakeup capability before setting device's capability, i.e. if (can_irq_wake(irq)) device_set_wakeup_capable(&client->dev, 1); But there is no can_irq_wake() call exist, and it is not that trivial to implement it for all interrupts controllers and complex/cascaded setups. drivers/base/power/sysfs.c also covers these cases: * Devices may not be able to generate wakeup events from all power * states. Also, the events may be ignored in some configurations; * for example, they might need help from other devices that aren't * active So there is no guarantee that wakeup will actually work, and so I think there is no point in being pedantic wrt checking IRQ wakeup capability.
