Hi,
I stumbled upon these upstream helpers while sorting out a merge
conflict and after looking around a bit, it turned out that these CTI
helpers have no users in mainline tree at all.
Introduced in commit 14eec97ff463 "arm: introduce cross trigger
interface helpers", these CTI helpers were intended to be used by
OMAP4 to route performance monitor irq to GIC. After scanning few git
logs, I run into few commits like [1][2] and comments in
"arch/arm/mach-omap2/pmu.c" which suggested that CTI driver for
OMAP4430 was never implemented or never submitted upstream(may be?).
I was just wondering if it make sense to send out a cleanup patch
upstream to remove these unused CTI helpers, if there is no activity
planned around it. Let me know your take on this.
Regards,
Amit Pundir
