* m68k: apollo, q40, sun3, sun3x: Remove arch_gettimeoffset implementationsFinn Thain2019-03-251-9/+0
| | | | | | | | These dummy implementations are no better than default_arch_gettimeoffset() so remove them. Signed-off-by: Finn Thain <fthain@telegraphics.com.au> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
* m68k: Call timer_interrupt() with interrupts disabledFinn Thain2019-03-251-8/+11
| | | | | | | | | | | | | | | Some platforms execute their timer handler with the interrupt priority level set below 6. That means the handler could be interrupted by another driver and this could lead to re-entry of the timer core. Avoid this by use of local_irq_save/restore for timer interrupt dispatch. This provides mutual exclusion around the timer interrupt flag access which is needed later in this series for the clocksource conversion.

* m68k: Remove unused set_clock_mmss() helpersArnd Bergmann2018-07-291-30/+0
| | | | | | | | | | | | | Commit 397ac99c6cef ("m68k: remove dead timer code") removed set_rtc_mmss() because it was unused in 2012. However, this was itself the only user of the mach_set_clock_mmss() callback and the many implementations of that callback, which are equally unused. This removes all of those as well.

* char/genrtc: remove m68k supportArnd Bergmann2016-06-041-1/+1
| | | | | | | | | | | | | | | | | The asm/rtc.h header is only used for the old gen_rtc driver that has been replaced by rtc-generic. According to Geert Uytterhoeven, nobody has used the old driver on m68k for a long time, so we can now just remove the header file and disallow the driver in Kconfig. All files that used to include asm/rtc.h are now changed so they include the headers that were used implicitly through asm/rtc.h.

* m68k: set arch_gettimeoffset directlyStephen Warren2012-12-241-4/+4
| | | | | | | | | | | | | | remove m68k's mach_gettimeoffset function pointer, and instead directly set the arch_gettimeoffset function pointer. This requires multiplying all function results by 1000, since the removed m68k_gettimeoffset() did this. Also, s/unsigned long/u32/ just to make the function prototypes exactly match that of arch_gettimeoffset.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
