Cover letter [PATCH 0/2] Couple of dmtimer fixes
Quoted 14 lines · Suman Anna

Hi Tony,

Please find couple of non-urgent fixes to the OMAP dmtimer driver. The patches are based on 4.0-rc1.

The first patch is a fix for the issue I reported earlier on the DRA7 dmtimer hwmod patches [1]. DRA7 has timers 13 through 16 disabled in DT currently, and enabling any of them would cause a kernel hang. This fix properly checks the pm_runtime_get_sync() calls in the OMAP dmtimer driver irrespective of whether the hwmods are added or not. In the case that they are not added, the runtime_pm calls should return the value as returned from _od_fail_runtime_resume(), and the probe should bail out properly fixing the boot hang.

Quoted 3 lines

Second patch is a minor fix that balances the pm_runtime_enable() call in probe with pm_runtime_disable() call in remove, so that the devices can be bound again properly after doing an unbind through sysfs.

OK thanks applying both into omap-for-v4.0/fixes.

Tony
