* 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: handle error when gpu failed to unpowergateKerwin Wan2015-03-18
| | | | | | | | | | | | | | | | | | | | | After flash, kernel needs to reboot after first boot. During reboot, devices is going to be shutdown including i2c. But sometimes gpu driver trys to open gpu sysfs nodes and unpowergate gpu at the same time. But i2c is already shutdown. tegra_unpowergate_partition returns error in this case but gk20a_tegra_unrailgate did not report the error so the error is not handled. Return proper value in gk20a_tegra_unrailgate to avoid this.
