Macros
#define	PBL_CLK_CONTROLLER_STATE_DEFINE(sym, _num_clks)
	Define the class state of clock controller sym, for the driver's define macro.
#define	PBL_CLK_CONTROLLER_INIT(sym, _name, _init, _parent, _ops)
	Initializer for the struct pbl_clk_controller of controller sym.
#define	PBL_CLK(_ctrl, _id)   {.ctrl = (_ctrl), .id = (_id)}
	Initializer for a struct pbl_clk.

Functions
int	pbl_clk_enable (const struct pbl_clk *clk)
	Take a reference on a clock, ungating it for the first user.
int	pbl_clk_disable (const struct pbl_clk *clk)
	Drop a reference on a clock, gating it after the last user.
bool	pbl_clk_is_enabled (const struct pbl_clk *clk)
	Check whether a clock has users.
