Function Documentation

int posix_clock_register	(	struct posix_clock *	clk,
		dev_t	devid
	)

posix_clock_register() - register a new clock : Pointer to the clock. Caller must provide 'ops' and 'release' : Allocated device id

A clock driver calls this function to register itself with the clock device subsystem. If 'clk' points to dynamically allocated memory, then the caller must provide a 'release' function to free that memory.

Returns zero on success, non-zero otherwise.

void posix_clock_unregister

(

struct posix_clock *

clk

)

posix_clock_unregister() - unregister a clock : Clock instance previously registered via posix_clock_register()

A clock driver calls this function to remove itself from the clock device subsystem. The posix_clock itself will remain (in an inactive state) until its reference count drops to zero, at which point it will be deallocated with its 'release' method.
