: name of this clock
clk_register_gate - register a gate clock with the clock framework : device that is registering this clock : name of this clock's parent : framework-specific flags for this clock : register address to control gating of this clock : which bit in the register controls gating of this clock : gate-specific flags for this clock : shared register lock for this clock

container_of(_hw, struct clk_gate, hw)

DOC: basic gatable clock which can gate and ungate it's ouput

Traits of this clock: prepare - clk_(un)prepare only ensures parent is (un)prepared enable - clk_enable and clk_disable are functional & control gating rate - inherits rate from parent. No clk_set_rate support parent - fixed parent. No clk_set_parent support
