pcm: Add sw_params API functions to get/set timestamp type
For obtaining / changing the timestamp type, add the corresponding sw_params accessor API functions together with the public definitions of timestamp types. This patch only adds the functions and defines but doesn't bring the functional changes yet. Signed-off-by: Takashi Iwai <tiwai@suse.de>
