Sounds about right, there are separate timers on omap1 and additional gp timers. There's no 32KiHz timer on 1510 variants, including 720 and 730. > Furthermore, you will get the above warning on a omap16xx only build if > you disable DM_TIMERs and keep MPU_TIMER enabled, which should be a > valid thing to do. > > Tony, I see you added the DM_TIMER dependency in commit > be26a008414414c69a4ae9fe9877401c3ba62c5a.

Hmm yes looks like you're right. That check be done based on !CONFIG_OMAP_32K_TIMER like you're saying.
