* gpu: nvgpu: gm20b: Regenerate clock gating listsTerje Bergstrom2015-03-18
| | | | | | | | | | Regenerate clock gating lists. Add new blocks, and takes them into use. Also moves some clock gating settings to be applied at the earliest possible moment right after reset.

* gpu: nvgpu: Wait for idle via FIFO registersTerje Bergstrom2015-03-18
| | | | | | | | | | | | | | Wait for engine idle via FIFO's engine status instead of submitting WFI to channel. Submitting WFI and waiting is not robust, and wait might invoke debug dump which cannot be done while powering down.

* gpu: nvgpu: fix memory leak of dbg_sessionDeepak Nibade2015-03-18
| | | | | | | | | | | | | | | | | | In gk20a_dbg_gpu_dev_release() (when we close nvhost-dgb-gpu sysfs), we return from function if there is no channel bound to dbg_session without freeing the dbg_session memory. If there is no channel bound then do not call dbg_unbind_channel_gk20a() and then free dbg_session memory always.

* gpu: nvgpu: gk20a: Control powergating on regopsSandarbh Jain2015-03-18
| | | | | | | | | | | | | | | Enable/disable powergating around regops so that the user need not call the powergating IOCTLs with the regops IOCTL. If the user does call the powergating IOCTL then the ref-counting will ensure the correct behavior.
