As dmtimer no longer exports functions, make those previously
exported static (this requires few functions to be moved around
as their prototypes were deleted).

Looks like this one fails to build with omap1_defconfig:

drivers/clocksource/timer-ti-dm.c:935:14: error:
'omap_dm_timer_get_fclk' undeclared here 

Other than that the first three patches seem like nice
clean-up :)

Regards,

Tony

Umm, it compiled fine on top of previous versions, so I didn't bother
to retest. I'm sorry about it.

So are you okay with sending those separately as cleanup with above
issue fixed?

But to be honest, I'm more interested how to do the last two patches
right ;-)

Yeah seems like those first three are suitable for applying
on top of the patches in omap-for-v4.17/timer :)

Yeah well if patch 4 can be sent separately as a fix, then
send that separately to Thierry?

Then you're just left with the pending pwm changes that
still need work it seems.

Tony

I've now applied your v2 of patch 1 and patches 2 and 3 of
this series into omap-for-v4.17/timer.

Thanks,
