* gpu: nvgpu: gk20a: fix syncpt names for gk20aDeepak Nibade2015-03-18
| | | | | | | | | | | | | | | | | | | | | | nvhost_get_syncpt_host_managed() creates syncpt name based on platform_device pointer passed to it Passing host1x's pointer to this API results in setting gk20a syncpt names as "host1x_0" which is conflicting Hence to restore this pass gk20a's device pointer which gives syncpt names as "gk20a.0_0" Also, add a syncpt check for sycnpt received.

* 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.

* gpu: nvgpu: Don't request host1x irq on channel wfiLauri Peltonen2015-03-18
| | | | | | | | | | | | | | | | | | Fix regression caused by commit 67fa249b419d32bfd0873fe5d924f4f01d9048de "video: tegra: host: Abstract gk20a channel synchronization". The above change unintentionally modified the channel synchronization logic so that an nvhost interrupt handler was scheduled also when idling the channel in gk20a_channel_submit_wfi. That appears to cause intermittent hangs when running CUDA tests.
