[PATCH 2/4] clocksource/drivers/timer-ti-dm: Update defines for am6 for inline functions

[Tony Lindgren]

We have pwm-omap-dmtimer tagged with COMPILE_TEST, so we need to use the
ifdefs around the inline functions. Let's add ARCH_K3 to the list of SoCs
to allow using timer-ti-dm on these SoCs.

[PATCH 4/4] clocksource/drivers/timer-ti-dm: Make timer selectable for ARCH_K3

[Tony Lindgren]

Let's make timer-ti-dm selectable for ARCH_K3, and add a separate option
for OMAP_DM_SYSTIMER as there should be no need for it on ARCH_K3.

For older TI SoCs, we are already selecting OMAP_DM_TIMER in
arch/arm/mach-omap*/Kconfig. For mach-omap2, we need to now also select
OMAP_DM_SYSTIMER.

Hmm that's a good question for why it was not that way earlier.

This series changes things for tristate "OMAP dual-mode timer driver" if
ARCH_K3 || COMPILE_TEST though. So the inline stubs are still needed for
COMPILE_TEST it seems.

Tony

Hmm that's a good question for why it was not that way earlier.

This series changes things for tristate "OMAP dual-mode timer driver" if
ARCH_K3 || COMPILE_TEST though. So the inline stubs are still needed for
COMPILE_TEST it seems.

Tony

But if ARCH_K3 or COMPILE_TEST is set, CONFIG_DM_TIMER is also set, no?

Right but I suspect that COMPILE_TEST will produce a build error on other
architectures. I need to check that though, maybe that is no longer the
case.

We could use IS_ENABLED(CONFIG_OMAP_DM_TIMER), but looks like we can now
just move the __omap_dm_timer_* inline functions to timer-ti-dm.c instead.

I'll do that and repost after some testing.

Suggestion:

Could we call this ti,am65-timer instead? AM6 is a bit nuanced and spans
a couple of sub SoC architectures.

OK I'll convert to yaml and send the binding patch separately.

OK I'll convert to yaml and send the binding patch separately.

I think the timer hardware is the same across am64, am65 and j7. So we
should pick something to represent the am6 timers as it would allow using
shared dtsi files for the 16 - 30 timers there are.

Using shared timer dtsi files should work as long as the clocks are
defined in include/dt-bindings/clock for each SoC, and assuming we can use
the same compatible property for the timers.

Of course if the timers are really different across am64, am65 and j72
then multiple compatible properties are neeeded.

If the timer hardware is the same, then I guess we should just pick the
earliest version, so how about using ti,am64-timer?

Tony

Compatible should work fine, Though I doubt clock and other indices
(base address etc will scale appropriately), but we could give it a
shot, but we can discuss that in the context of the dts patches.

yep - the oldest version will be ti,am654-timer ( AM65 was the first
K3 device. Unfortunately, the numbering does'nt follow a chronological
order)

yep - the oldest version will be ti,am654-timer ( AM65 was the first

Yeah that's a separate series for sure and can be done later on after we
have am6 timers working first.

OK great, I will use ti,am654-timer then.
