2018-03-09T22:19:56+00:00

Remove the MN10300 arch as the hardware is defunct.

mn10300: use RTC_DRV_CMOS instead of CONFIG_RTC

2016-06-25T23:20:08+00:00

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 support

2016-06-03T22:23:03+00:00

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 once

2011-01-13T16:03:07+00:00

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 SMP

2010-10-27T16:28:55+00:00

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 routines

2010-08-12T16:51:35+00:00

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.

mn10300: Convert mn10300 to use read/update_persistent_clock

2010-03-13T00:14:09+00:00

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 kernel

2008-02-08T17:22:30+00:00

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.
