2012-12-18rtc: rtc-spear: Add clk_{un}prepare() supportDeepak Sikri1-3/+3
clk_{un}prepare is mandatory for platforms using common clock framework. Because for SPEAr we don't do anything in clk_{un}prepare() calls, just call them once in probe/remove.

2012-12-18rtc: rtc-spear: use devm_*() routinesViresh Kumar1-60/+29

2012-12-18drivers/rtc/rtc-test.c: avoid calling platform_device_put() twiceWei Yongjun1-7/+7
In case of error, test_init() needs to call platform_device_del() instead of platform_device_unregister(). Otherwise, we may call platform_device_put() twice. dpatch engine is used to auto generate this patch.

2012-12-18rtc: omap: add runtime pm supportVaibhav Hiremath1-0/+18
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.

2012-12-18rtc: omap: kicker mechanism supportAfzal Mohammed1-3/+41
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: Afzal Mohammed <afzal@ti.com> Acked-by: Sekhar Nori <nsekhar@ti.com> Cc: Grant Likely <grant.likely@secretlab.ca> Cc: Sekhar Nori <nsekhar@ti.com> Cc: Kevin Hilman <khilman@ti.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: Alessandro Zummo <a.zummo@towertech.it> Cc: Daniel Mack <zonque@gmail.com> Cc: Vaibhav Hiremath <hvaibhav@ti.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2012-10-11rtc: kconfig: fix RTC_INTF defaults connected to RTC_CLASSKevin Hilman1-0/+3
Commit 6b8029fab641 ("rtc: kconfig: remove unnecessary dependencies") removed various 'depends on RTC_CLASS' dependencies but also removed a few 'default RTC_CLASS' statements, which actually changed default behavior. This resulted in the various RTC interfaces (sysfs, proc, dev) all being disabled by default, even when RTC_CLASS is enabled: # CONFIG_RTC_INTF_SYSFS is not set # CONFIG_RTC_INTF_PROC is not set # CONFIG_RTC_INTF_DEV is not set which is different from previous behavior (all of these where enabled.) To fix, add back the 'default RTC_CLASS' statments to each of the RTC_INTF_* options. I noticed this because some RTC tests started failing on my TI OMAP platforms because /dev/rtc0 was not present anymore, even though the driver was present and RTC_CLASS was enabled.

2012-10-05rtc_sysfs_show_hctosys(): display 0 if resume failedDavid Fries3-4/+14
Without this patch /sys/class/rtc/$CONFIG_RTC_HCTOSYS_DEVICE/hctosys contains a 1 (meaning "This rtc was used to initialize the system clock") even if setting the time by do_settimeofday() at bootup failed. The RTC can also be used to set the clock on resume, if it did 1, otherwise 0. Previously there was no indication if the RTC was used to set the clock in resume. This uses only CONFIG_RTC_HCTOSYS_DEVICE for conditional compilation instead of it and CONFIG_RTC_HCTOSYS to be more consistent. rtc_hctosys_ret was moved to class.c so class.c no longer depends on hctosys.c.

2012-10-05drivers/rtc/rtc-spear.c: fix several error checksLars-Peter Clausen1-7/+5
There are several comparisons of a unsigned int to less than zero int spear RTC driver. Such a check will always be true. In all these cases a signed int is assigned to the unsigned variable, which is checked, before. So the right fix is to make the checked variable signed as well. In one case the check can be dropped completely, because all it does it returns 'err' if 'err' is less than zero, otherwise it returns 0. Since in this particular case 'err' is always either 0 or less this is the same as just returning 'err'.

2012-10-05drivers/rtc/rtc-jz4740.c: fix IRQ error checkLars-Peter Clausen1-1/+1
The irq field of the jz4740_irc struct is unsigned. Yet we assign the result of platform_get_irq() to it. platform_get_irq() may return a negative error code and the code checks for this condition by checking if 'irq' is less than zero. But since 'irq' is unsigned this test will always be false. Fix it by making 'irq' signed.

2012-10-05rtc: recycle id when unloading a rtc driverVincent Palatin1-0/+1
When calling rtc_device_unregister, we are not freeing the id used by the driver. So when doing a unload/load cycle for a RTC driver (e.g. rmmod rtc_cmos && modprobe rtc_cmos), its id is incremented by one. As a consequence, we no longer have neither an rtc0 driver nor a /proc/driver/rtc (as it only exists for the first driver).
