* gpu: nvgpu: Power on platform deps for wfiArto Merilainen2015-03-18
| | | | | | | | | | | | | | | | | | | | | | | Currently gk20a_channel_idle() drops pm_runtime references to gk20a and then drops platform dependencies. As we usually delay powering down gk20a, we may end up to case where the platform dependencies are turned off at the moment we start powering down gk20a. Power off sequence may use platform dependencies for informing completion of the last work, wait-for-idle, and therefore we may simply drop the information about job completion. This patch adds missing calls to power up platform dependencies for the time we submit the last work.
