struct clk - OMAP struct clk : list_head connecting this clock into the full clock list : struct clkops * for this clock : pointer to this clock's parent struct clk : list_head connecting to the child clks' list_heads : list_head connecting this clk to its parent clk's : current clock rate : register to write to enable the clock (see ) : fn ptr that returns the clock's current rate : fn ptr that can change the clock's current rate : fn ptr that can round the clock's current rate : fn ptr to do clock-specific initialization : bitshift to write to enable/disable the clock (see ) : number of users that have requested this clock to be enabled : when > 0, this clock's rate is its parent's rate / : see "struct clk.flags possibilities" above : for clksel clks, register va containing src/divisor select : bitmask in for the src/divisor selector : for clksel clks, pointer to struct clksel for this clock : for DPLLs, pointer to struct dpll_data for this clock : clockdomain name that this clock is contained in : pointer to struct clockdomain, resolved from at runtime : bitshift for rate selection bitfield (OMAP1 only) : bitshift for source selection bitfield (OMAP1 only) XXX , should probably be removed and OMAP1 clock code converted to use clksel. XXX is poorly named. It should be "enable_count" or something similar. "users" in the description refers to kernel code (core code or drivers) that have called clk_enable() and not yet called clk_disable(); the usecount of parent clocks is also incremented by the clock code when clk_enable() is called on child clocks and decremented by the clock code when clk_disable() is called on child clocks. XXX , , , should be marked for internal use only. and are used to optimize parent-to-child clock tree traversals. (child-to-parent traversals use .) XXX The notion of the clock's current rate probably needs to be separated from the clock's target rate. | |
