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.

Actually, I missed this. Could you convert to a 'bool' there is no 
module in the timer drivers ATM.

OK sure will do.

Did you notice some loadable module usage issues for timers that are not
system timers? Just wondering if there are some issues that I did not
notice.

Regards,

Tony

I think the removal won't be supported. We already had a proposal to 
move one of the timer as a module but I wanted to have more insights 
about the changes, not just do that because of a GKI Android.

OK good to know.
