headers: separate linux/mod_devicetable.h from linux/platform_device.h

2018-07-07T15:52:26Z

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

rtc: mxc_v2: use rtc_time64_to_tm in mxc_rtc_read_alarm

2018-05-19T08:50:03Z

Use the 64-bit version of rtc_time_to_tm in mxc_rtc_read_alarm Signed-off-by: Alexandre Belloni

rtc: mxc_v2: let the core handle rtc range

2018-05-19T08:47:46Z

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

rtc: mxc_v2: fix possible race condition

2018-05-19T08:47:46Z

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

rtc: mxc_v2: Fix _iomem pointer notation

2018-03-01T09:49:36Z

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] *addr drivers/rtc/rtc-mxc_v2.c:280:18: got void *[noderef] 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] ioaddr drivers/rtc/rtc-mxc_v2.c:329:44: got void [noderef] * 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] ioaddr drivers/rtc/rtc-mxc_v2.c:339:44: got void [noderef] * Signed-off-by: Fabio Estevam Signed-off-by: Alexandre Belloni

rtc: mxc_v2: remove __exit annotation

2018-01-11T23:20:40Z

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.

rtc: mxc_v2: Remove unnecessary platform_get_resource() error check

2018-01-11T23:20:40Z

devm_ioremap_resource() already checks if the resource is NULL, so remove the unnecessary platform_get_resource() error check. Signed-off-by: Fabio Estevam Signed-off-by: Alexandre Belloni

rtc: add mxc driver for i.MX53 SRTC

2018-01-11T23:20:39Z

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 Acked-by: Philippe Ombredanne Signed-off-by: Alexandre Belloni
