2008-05-13rtc: rtc_time_to_tm: use unsigned arithmeticMaciej W. Rozycki1-1/+1
The input argument to rtc_time_to_tm() is unsigned as well as are members of the output structure. However signed arithmetic is used within for calculations leading to incorrect results for input values outside the signed positive range. If this happens the time of day returned is out of range. Found the problem when fiddling with the RTC and the driver where year was set to an unexpectedly large value like 2070, e.g.: rtc0: setting system clock to 2070-01-01 1193046:71582832:26 UTC (3155760954) while it should be: rtc0: setting system clock to 2070-01-01 00:15:54 UTC (3155760954) Changing types to unsigned fixes the problem.

2008-05-11i2c: Match dummy devices by typeJean Delvare1-1/+1
As the old driver_name/type matching scheme is going away soon, change the dummy device mechanism to use the new matching scheme. This has the downside that dummy i2c clients can no longer choose their name, they'll all appear as "dummy" in sysfs and in log messages. I don't think it is a problem in practice though, as there is little reason to use these i2c clients to log messages. Signed-off-by: Jean Delvare <[email protected]>

2008-05-08fix irq flags in rtc-ds1511Steven Rostedt1-2/+2
The file in drivers/rtc/rtc-ds1551.c uses "int" for flags. This can cause hard to find bugs on some architectures. This patch converts the flags to use "long" instead. This bug was discovered by doing an allyesconfig make on the -rt kernel where checks are done to ensure all flags are of size sizeof(long).

2008-04-29i2c: Convert most new-style drivers to use module aliasingJean Delvare8-110/+90
Based on earlier work by Jon Smirl and Jochen Friedrich. Update most new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme.

2008-04-28rtc: add the support for alarm time relative to current time in sysfsZhao Yakui1-1/+11
In current kernel if we want to set the alarm time, the absolute time the seconds relative to 1970-01-01 00:00:00) should be written into /sys/class/rtc/rtc0/wakealarm. It is not convenient. It is more reasonable to add the support for the alarm time relative to current RTC time.(the unit is second) For example: If the RTC is required to generate alarm after 2 minutes, the following will be OK. echo +120 > /sys/class/rtc/rtc0/wakealarm or echo +0x78 > /sys/class/rtc/rtc0/wakealarm Signed-off-by: Zhao Yakui <[email protected]> Signed-off-by: Zhang Rui <[email protected]> Signed-off-by: David Brownell <[email protected]> Cc: Alessandro Zummo <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

The earliest we can get at the symbolic name is via the i2c client's struct device, which can be handled by moving the first rs5c_get_regs() until after the client pointer is assigned.

2008-04-28rtc: avoid legacy drivers with generic frameworkDavid Brownell1-4/+1
Kconfig tweaks to help reduce RTC configuration bugs, by avoiding legacy RTC drivers when the generic RTC framework is enabled: - If rtc-cmos is selected, disable the legacy rtc driver; - When using generic RTC on x86, enable rtc-cmos by default; - In the old "chardev RTC" section of Kconfig, add a comment warning people off these (seven) legacy RTC drivers when the generic framework is in use. People can still use the legacy drivers if they want (or need) to. This doesn't fix the broken dependencies for the legacy "CMOS" RTC driver. Ideally it would be a full list of platforms where it works, not a partial list of ones where it won't. Or better yet, it would depend on a "HAVE_CMOS_RTC" flag defined by various platforms ... surely there's a Kconfig style guideline lurking there.

2008-02-06rtc: at91sam9 RTC support (RTT and/or RTC)David Brownell3-4/+562
AT91sam9 RTC support, primarily in the form of an RTT-as-RTC driver that was extracted from 2.6.23-at91 patch and updated: - Relies on now-merged platform updates, which associate the RTT hardware address with each RTT and use the "at91_rtt" name. - RTC framework related fixes and cleanups, notably: * removed now-needless suspend/resume clock offset logic * alarm read/write now respects the "enabled" flag * suspend always disables update irqs * shutdown (and startup) disables all irqs - Misc cleanup: * use dev_*() messaging * add comments * remove globals, * ... etc - Don't force use of RTT0 and GPBR0. Either resource may need to be used for other purposes (like NO_HZ support). - Update "AT91RM9200 RTC" Kconfig to allow it on SAM9RL chips (it has both RTT and RTC). Driver binding uses bus_find_device() to avoid needing any kind of "timer library" code when there's more than one RTT module. (This timer can be used as an RTC, to support NO_HZ operation, or potentially for other stuff. The choice is a per-system policy.)

2008-02-06rtc-cmos alarm acts as oneshotDavid Brownell3-7/+35
Start making the rtc-cmos alarm act more like a oneshot alarm by disabling that alarm after its IRQ fires. (ACPI hooks are also needed.) The Linux RTC framework has previously been a bit vague in this area, but any other behavior is problematic and not very portable. RTCs with full YYYY-MM-DD HH:MM[:SS] alarms won't have a problem here. Only ones with partial match criteria, with the most visible example being the PC RTC, get confused. (Because the criteria will match repeatedly.) Update comments relating to that oneshot behavior and timezone handling. (Timezones are another issue that's mostly visible with rtc-cmos. That's because PCs often dual-boot MS-Windows, which likes its RTC to match local wall-clock time instead of UTC.)

2008-02-06rtc: ds1302 rtc supportPaul Mundt3-0/+269
This adds a basic ds1302 RTC driver, which is basically a cleanup and move of the in-tree SH SecureEdge5410 code (which is currently located in arch/sh/board/snapgear/rtc.c) to drivers/rtc. This aims to be a building block that the M32R and CRIS code can be worked on top of, so we can get rid of drivers/char/ds1302.c and arch/cris/arch-v10/drivers/ds1302.c respectively, though more work is needed for this.

2008-02-06rtc-cmos: export nvram in sysfsDavid Brownell1-12/+117
This makes rtc-cmos export its NVRAM, like several other RTC drivers. It still works within the limits of the current CMOS_READ/CMOS_WRITE calls, which don't understand how to access multiple register banks. The primary impact of that limitation is that Linux can't access the uppermost 128 bytes of NVRAM on many systems. Note that this isn't aiming to be a drop-in replacement for the legacy /dev/nvram support. (Presumably that has real users, and isn't just getting carried forward automatically?) Userspace handles more work: - When userspace code updates NVRAM, that will need to include updating any platform-specific checksums that may apply. - No /proc/driver/nvram file will parse and display NVRAM data according to whichever boot firmware your board expects. Also minor pnp-related updates: update a comment, remove dead code.
