* rtc: rs5c372: Fix reading from rtc when the oscillator got interrupted.Oliver.Rohe@wago.com2019-02-111-7/+47
| | | | | | | | | When the oscillator of the rtc gets interrupted, e.g. due to an empty battery, reading from the rtc will now return an error and the oscillator bit will be cleared, once the rtc is successfully reset.

* rtc: rs5c372: Add OF device ID tableJavier Martinez Canillas2017-03-091-1/+36
| | | | | | | | | | | | | The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

* rtc: remove useless DRV_VERSIONAlexandre Belloni2016-05-201-5/+1
| | | | | | | | | Many drivers are defining a DRV_VERSION. This is often only used for MODULE_VERSION and sometimes to print an info message at probe time. This is kind of pointless as they are all versionned with the kernel anyway. Also the core will print a message when a new rtc is found.

* RTC: Convert rtc drivers to use the alarm_irq_enable methodJohn Stultz2011-02-031-14/+34
| | | | | | | | | | | | | | | | | | | Some rtc drivers use the ioctl method instead of the alarm_irq_enable method for enabling alarm interupts. With the new virtualized RTC rework, its important for drivers to use the alarm_irq_enable instead. This patch converts the drivers that use the AIE ioctl method to use the alarm_irq_enable method. Other ioctl cmds are left untouched. I have not been able to test or even compile most of these drivers. Any help to make sure this change is correct would be appreciated!

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* rtc: rtc-rs5c372: SMBus conversion/supportPaul Mundt2008-10-161-78/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | rtc-rs5c372 presently depends on I2C master mode transfers, despite the fact that these RTCs frequently find themselves on SMBus-only adapters. Given that the only capabilities that were checked were for I2C_FUNC_I2C, it's assumed that most of the adapters that are currently using this driver are fairly sane, and are able to handle SMBus emulation (though we adjust the default capabilities to check for I2C_FUNC_SMBUS_EMUL anyways, which is the vast majority of them. The adapters that don't have their own ->smbus_xfer() fall back on the ->master_xfer() through the emulated transfer). The special case is iop3xx, which has more than its fair share of hacks within this driver, it remains untested -- though also claims to support emulated SMBus accesses. The corner case there is rs5c_get_regs() which uses access mode #3 for transferring the register state, while we use mode #1 for SMBus.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bugfixes: - Handle RTCs which are configured to use 12-hour mode. - Never report bogus/un-initialized times. - Displaying "raw trim" requires not masking it first! - Fix the sysfs and procfs display of crystal and trim data. Features: - Handle other RTCs in this family, notably rv5c386/rv5c387. - Declare the other registers. - Provide alarm get/set functionality. - Handle AIE and UIE; but no IRQ handling yet. Cleanup: - Shrink object by not including needless sysfs or procfs support - We don't need no steenkin' forward declarations. (Except one.) Until the I2C framework merges "new style" driver support, matching the driver model better, using rv5c chips or alarm IRQs requires a separate board-specific patch. (And an IRQ handler, handing off labor through a work_struct...) This uses the "method 3" register reads, but notes that it's done to work around an evident i2c adapter driver bug.
