21 details of its counterpart.  First is the common definition of struct
25 drivers/clk/clk.c.  Finally there is struct clk_ops, whose operations
29 callbacks registered with struct clk_ops and the corresponding
31 the remainder of this document any reference to a callback in struct
33 implementation of that code.  Likewise, references to struct clk_foo
37 Tying the two halves of this interface together is struct clk_hw, which
38 is defined in struct clk_foo and pointed to within struct clk_core.  This
45 Below is the common struct clk_core definition from
48 	struct clk_core {

63 struct clk.  That api is documented in include/linux/clk.h.
65 Platforms and devices utilizing the common struct clk_core use the struct
66 clk_ops pointer in struct clk_core to perform the hardware-specific parts of

106 The strength of the common struct clk_core comes from its .ops and .hw pointers
107 which abstract the details of struct clk from the hardware-specific bits, and
111 	struct clk_gate {
112 		struct clk_hw	hw;
118 struct clk_gate contains struct clk_hw hw as well as hardware-specific
122 framework code and struct clk_core.
126 	struct clk *clk;
138 			[resolves struct clk gate with to_clk_gate(hw)]

244 registration function.  This function simply populates struct clk_foo's
245 data and then passes the common struct clk parameters to the framework
