My mistake, the code has changed several times and I adapted it to
the latest version each time, but the version I sent out is indeed
useless.

The only hunk that still makes sense is

diff --git a/arch/arm/mach-omap2/timer.c b/arch/arm/mach-omap2/timer.c
index b18ebbefae09..b7ab09cc5ca2 100644

 {
 	__omap_sync32k_timer_init(12, "secure_32k_fck", "ti,timer-secure",


but that is harmless as it does not cause a build error, just a few extra
bytes for an unused function in a AM43XX-only configuration.
