s3c24xx_register_clock() - register a clock : The clock to register

Add the specified clock to the list of clocks known by the system.

Definition at line 281 of file clock.c.

int s3c24xx_register_clocks	(	struct clk **	clks,
		int	nr_clks
	)

s3c24xx_register_clocks() - register an array of clock pointers : Pointer to an array of struct clk pointers : The number of clocks in the array.

Call s3c24xx_register_clock() for all the clock pointers contained in the list. Returns the number of failures.

s3c_disable_clocks() - disable an array of clocks : Pointer to the first clock in the array. : Number of clocks to register.

for internal use only at initialisation time. disable the clocks in the array.

s3c_pwmclk_init() - initialise pwm clocks

Initialise and register the clocks which provide the inputs for the pwm timer blocks.

Note, this call is required by the time core, so must be called after the base clocks are added and before any of the initcalls are run.

Definition at line 440 of file pwm-clock.c.

void s3c_register_clocks	(	struct clk *	clkp,
		int	nr_clks

s3c_register_clocks() - register an array of clocks : Pointer to the first clock in the array. : Number of clocks to register.

Call s3c24xx_register_clock() on the array given, printing an error if it fails to register the clock (unlikely).
