* mn10300: use RTC_DRV_CMOS instead of CONFIG_RTCArnd Bergmann2016-06-261-95/+9
| | | | | | | | | | | | | nn10300 has a dependency on mc146818_get_time/mc146818_set_time, which we want to move from the mc146818rtc.h header into the rtc subsystem, which in turn is not usable on mn10300. This changes mn10300 to use the modern rtc-cmos driver instead of the old RTC driver, and that in turn lets us completely remove the read_persistent_clock/update_persistent_clock callbacks.

* char/genrtc: remove mn10300 supportArnd Bergmann2016-06-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | The genrtc driver serves no purpose on mn10300 because it drives the same hardware as the original rtc.c driver, and the newer rtc-generic.c or rtc-cmos.c drivers on architectures that use the asm-generic/rtc.h header. I assume it was initially only added for completeness when the mn10300 port was done, but the older rtc.c driver was always used instead. We can also stop include asm-generic/rtc.h now, because we just call mc146818_set_time() directly. It would be nice to change the architecture to use the rtc-cmos driver next, and remove support for the old rtc driver as well.

* set_rtc_mmss: show warning message only onceStephen Hemminger2011-01-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Occasionally the system gets into a state where the CMOS clock has gotten slightly ahead of current time and the periodic update of RTC fails. The message is a nuisance and repeats spamming the log. See: http://www.ntp.org/ntpfaq/NTP-s-trbl-spec.htm#Q-LINUX-SET-RTC-MMSS Rather than just removing the message, make it show only once and reduce severity since it indicates a normal and non urgent condition.

* MN10300: And Panasonic AM34 subarch and implement SMPAkira Takeuchi2010-10-271-31/+10
| | | | | | | | | | Implement the Panasonic MN10300 AM34 CPU subarch and implement SMP support for MN10300. Also implement support for the MN2WS0060 processor and the ASB2364 evaluation board which are AM34 based.

* MN10300: Fix RTC routinesDavid Howells2010-08-121-4/+1
| | | | | | | | | A change to the RTC routines in the MN10300 arch used set_rtc_mms() when it meant set_rtc_mmss(). This results in an error due to a reference of an undefined symbol. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* mn10300: Convert mn10300 to use read/update_persistent_clockJohn Stultz2010-03-131-22/+5
| | | | | | | | | | | | | | | | | This patch converts the mn10300 architecture to use the generic read_persistent_clock and update_persistent_clock interfaces, reducing the amount of arch specific code we have to maintain, and allowing for further cleanups in the future. I have not built or tested this patch, so help from arch maintainers would be appreciated.

* mn10300: add the MN10300/AM33 architecture to the kernelDavid Howells2008-02-081-0/+173
Add architecture support for the MN10300/AM33 CPUs produced by MEI to the kernel. This patch also adds board support for the ASB2303 with the ASB2308 daughter board, and the ASB2305. The only processor supported is the MN103E010, which is an AM33v2 core plus on-chip devices.
