SLPI (sensor low power island) uses Qualcomm Technologies, Inc
Digital Signal Processor for all sensors connected via SPI/I2C.
Firmware is required to be loaded to enable these sensors and
algorithms to execute on DSP. This change adds driver to load
the firmware.
This snapshot is taken as of msm-4.14 commit <2af01acb8e045>
("clk: qcom: gdsc: Remove global mutex lock in enable/disable
callbacks")' and minor modifications in Documentation.
