2019-07-22rtc: mxc_v2: use devm_platform_ioremap_resource() to simplify codeAnson Huang1-3/+1
Use the new helper devm_platform_ioremap_resource() which wraps the platform_get_resource() and devm_ioremap_resource() together, to simplify the code.

2019-04-11rtc: mxc_v2: use dev_pm_set_wake_irq() to simplify codeAnson Huang1-25/+4
With calling dev_pm_set_wake_irq() to set MXC_V2 RTC as wakeup source for suspend, generic wake irq mechanism will automatically enable it as wakeup source when suspend, then the suspend/resume callback which are ONLY for enabling/disabling irq wake can be removed, it simplifies the code.

2018-07-07headers: separate linux/mod_devicetable.h from linux/platform_device.hRandy Dunlap1-0/+1
At over 4000 #includes, <linux/platform_device.h> is the 9th most #included header file in the Linux kernel. It does not need <linux/mod_devicetable.h>, so drop that header and explicitly add <linux/mod_devicetable.h> to source files that need it. 4146 #include <linux/platform_device.h> After this patch, there are 225 files that use <linux/mod_devicetable.h>, for a reduction of around 3900 times that <linux/mod_devicetable.h> does not have to be read & parsed. 225 #include <linux/mod_devicetable.h> This patch was build-tested on 20 different arch-es. It also makes these drivers SubmitChecklist#1 compliant.

2018-05-19rtc: mxc_v2: use rtc_time64_to_tm in mxc_rtc_read_alarmAlexandre Belloni1-1/+1
Use the 64-bit version of rtc_time_to_tm in mxc_rtc_read_alarm Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-05-19rtc: mxc_v2: let the core handle rtc rangeAlexandre Belloni1-10/+1
This RTC is a 32-bit second counter. This also solves an issue where mxc_rtc_set_alarm() can return with the lock taken. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-05-19rtc: mxc_v2: fix possible race conditionAlexandre Belloni1-7/+9
The IRQ is requested before the struct rtc is allocated and registered, but this struct is used in the IRQ handler. This may lead to a NULL pointer dereference. Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc before requesting the IRQ. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-03-01rtc: mxc_v2: Fix _iomem pointer notationFabio Estevam1-1/+1
Fix the iomem pointer notation in order to fix the following sparse warnings: drivers/rtc/rtc-mxc_v2.c:280:18: warning: incorrect type in argument 1 (different address spaces) drivers/rtc/rtc-mxc_v2.c:280:18: expected void const volatile [noderef] <asn:2>*addr drivers/rtc/rtc-mxc_v2.c:280:18: got void *[noderef] <asn:2>ioaddr drivers/rtc/rtc-mxc_v2.c:329:44: warning: incorrect type in argument 1 (different address spaces) drivers/rtc/rtc-mxc_v2.c:329:44: expected void *[noderef] <asn:2>ioaddr drivers/rtc/rtc-mxc_v2.c:329:44: got void [noderef] <asn:2>* drivers/rtc/rtc-mxc_v2.c:339:44: warning: incorrect type in argument 1 (different address spaces) drivers/rtc/rtc-mxc_v2.c:339:44: expected void *[noderef] <asn:2>ioaddr drivers/rtc/rtc-mxc_v2.c:339:44: got void [noderef] <asn:2>* Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-01-12rtc: mxc_v2: remove __exit annotationArnd Bergmann1-1/+1
The mxc_rtc_remove is incorrectly annotated as __exit: `mxc_rtc_remove' referenced in section `.data' of drivers/rtc/rtc-mxc_v2.o: defined in discarded section `.exit.text' of drivers/rtc/rtc-mxc_v2.o This should not be done, as devices can be dynamically bound and unbound to a driver.

2018-01-12rtc: mxc_v2: Remove unnecessary platform_get_resource() error checkFabio Estevam1-3/+0
devm_ioremap_resource() already checks if the resource is NULL, so remove the unnecessary platform_get_resource() error check. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
2018-01-12rtc: add mxc driver for i.MX53 SRTCPatrick Bruenn1-0/+422
Neither rtc-imxdi, rtc-mxc nor rtc-snvs are compatible with i.MX53. This is driver enables support for the low power domain SRTC features: - 32-bit MSB of non-rollover time counter - 32-bit alarm register Select the new config option RTC_DRV_MXC_V2 to build this driver Based on: http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/drivers/rtc/rtc-mxc_v2.c?h=imx_2.6.35_11.09.01 Signed-off-by: Patrick Bruenn <p.bruenn@beckhoff.com> Acked-by: Philippe Ombredanne <pombredanne@nexb.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
