* gpu: nvgpu: gk20a: add busy lockDeepak Nibade2015-03-18
| | | | | | | | | | | | | | | | - add rw_semaphore busy_lock for gpu busy() path - take read lock on busy_lock inside gk20a_busy() so that all usual requests can execute simultaneously - write lock can be taken when we need to block all of the gk20a_busy() calls Bug 1487804 Change-Id: I1b162b38bce9621723d3e45280c6076816cf771a Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/412060 Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Tested-by: Terje Bergstrom <tbergstrom@nvidia.com>

* gpu: nvgpu: Get host1x device from DTSArto Merilainen2015-03-18
| | | | | | | | | | | | | | | Currently the gpu driver assumes that the GPU is a child of host1x. This is an invalid assumption and therefore we need to get the host1x device from device tree based on nvidia,host1x property.
