start reading temperature from sensor to evaluate VFE equations
2)Send GP106's temp min and max range for GPU sensor so that PMU

3)PMU will send event whenever temperature goes above +ve hysteresis

The arbiter is charged with selecting the proper
frequencies when multiple applications submit
simultaneously clock change requests
On the current implementation, the arbiter guarantees
that the selected frequency will be always higher
or equal to the request, as long as the request is
in range.
The current code is not yet realtime friendly, as
requests are not pre-allocated.
Summary of changes:
(1) pstate/vf switch no longer selects boot frequency
(2) changed mclk code change to accept input freq
(3) added arbiter
(4) now a single session can submit concurrent requests
the last request is the one that applies for that
session
(5) modified locking mechanism to reduce lock contention
(6) Added callback to notify the arbiter that the VF
table has changed and is no longer valid (PMU/Thermals
must call this when VF table is invalid)
(7) changed internal API to work with MHz
(8) added debugfs for stats

handling of clock requests. Provides minimum behaviour to allow

one is not found. This situation is normal. This is done by moving

nvgpu_request_firmware(), and adding a NO_WARN flag to

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.
