* gpu: nvgpu: Disable GM20b clock slowdown for monitorAlex Frid2015-03-18
| | | | | | | | | | | Disabled GM20b idle clock slowdown during rate measurements.

* gpu: nvgpu: Don't increase GPCPLL rate before bypassAlex Frid2015-03-18
| | | | | | | | | | | | | | | | Do not force GM20b GPCPLL post divider to 1:2 settings before switching to bypass clock if PLL output frequency is increased as a result. Move this step under bypass. However, this step is still needed in case when PLL can be configured without switch to bypass.

* arm: tegra: Register tegra-throttle cdev as driverArun Kumar Swain2015-03-18
| | | | | | | | | | | | | | 1. Register tegra-throttle cooling device as a platform driver. 2. Obtain all the platform data (throtlle table info) for all instances of blanced-throtlled cdev from device tree and register them.

* gpu: nvgpu: Update GM20B GPCPLL programming sequenceAlex Frid2015-03-18
| | | | | | | | | | | | | | | | Updated GM20B GPCPLL programming sequence to utilize new glitch-less post divider: - No longer bypass PLL for re-locking if it is already enabled, and post divider as well as feedback divider are changing (input divider change is still under bypass only). - Use post divider instead of external linear divider to introduce (VCO min/2) intermediated step when changing PLL frequency.

* gpu: nvgpu: Updated GM20b GPCPLL dynamic ramp setupAlex Frid2015-03-18
| | | | | | | | | | | Setup GPCPLL dynamic ramp coefficients based on update rate (instead of hard-coding), since on GM20B high reference clock 38.4MHz allows to use several update rates within supported range.

* gpu: nvgpu: Update GM20b GPCPLL parametersAlex Frid2015-03-18
| | | | | | | | | | | | | | | | | | | Updated GPCPLL parameters according to GM20b specification. Modified PLL programming, since on GM20b PLL post divider value is equal to divider setting (which was not the case on GK20a this code was inherited from).

| | | | | | | | | | | | | | | | | | | - Set initial output rate to 1/3 of VCO minimum. - Cleared global BYPASSCTRL to get ready for enabling PLL (this won't bring PLL out of bypass, since SEL_VCO register is cleared). - Added debugfs nodes for BYPASSCTRL and SEL_VCO state.
