Values are "auto", "manual". In "auto" 158 mode, the driver will set the maximum clock frequency to a high 159 value when a user-space process opens the device's file (unless 160 it was already opened by another process). The driver will set 161 the max clock frequency to a low value when there are no user 162 processes that are opened on the device's file. In "manual" 163 mode, the user sets the maximum clock frequency by writing to 164 ic_clk, mme_clk and tpc_clk.
