Values are "auto", "manual". In "auto" 164 mode, the driver will set the maximum clock frequency to a high 165 value when a user-space process opens the device's file (unless 166 it was already opened by another process). The driver will set 167 the max clock frequency to a low value when there are no user 168 processes that are opened on the device's file. In "manual" 169 mode, the user sets the maximum clock frequency by writing to 170 ic_clk, mme_clk and tpc_clk.
