* gpu: nvgpu: use gm20b.gbus instead of gpcclkSrikar Srimath Tirumala2017-01-30

Make T210 K4.4 use gm20b.gbus to change the GPU clk rates and use its parent clock gbus while querrying DVFS constraints for the GPU.

* gpu: nvgpu: use HAL to set TSG timesliceThomas Fleury2017-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | Setting timeslice for virtualized case was not effective, because both ioctls NVGPU_TSG_IOCTL_SET_TIMESLICE and NVGPU_SCHED_IOCTL_TSG_SET_TIMESLICE were calling the native function to set TSG timeslice. - Fixed wrapper function to call HAL - Defined HAL function for "native" set TSG timeslice - Also, properly update timeout_us in TSG context, in virtualized case. This change also moves the min/max bounds checking for tsg timeslice into the native function implementation. There is no sysfs node for these parameters for vgpu, as RM server is ultimately responsible for this check.

| | | | | | | | | | | | | | | | | | | | Suppress error message when nvgpu tries to load VBIOS overlay, but one is not found. This situation is normal. This is done by moving gk20a_request_firmware() to be nvgpu generic function nvgpu_request_firmware(), and adding a NO_WARN flag to it. Introduce also a NO_SOC flag to suppress attempt to load firmware from SoC specific directory in addition to the chip specific directory. Use it for dGPU firmware files.
