Description:    Allows the user to set the maximum clock frequency of the
                MME compute engine. Writes to this parameter affect the device
                only when the power management profile is set to "manual" mode.
                The device MME clock might be set to lower value then the
                maximum. The user should read the mme_clk_curr to see the actual
                frequency value of the MME

Date:           Jan 2019
KernelVersion:  5.1
Contact:        [e-mail]
Description:    Power management profile. Values are "auto", "manual". In "auto"
                mode, the driver will set the maximum clock frequency to a high
                value when a user-space process opens the device's file (unless
                it was already opened by another process). The driver will set
                the max clock frequency to a low value when there are no user
                processes that are opened on the device's file. In "manual"
                mode, the user sets the maximum clock frequency by writing to
                ic_clk, mme_clk and tpc_clk
