[PATCH] pmac: Improve sleep code of tumbler driver
This patch improves the behaviour of the "tumbler/snapper" driver used on newer PowerMacs during sleep. It properly set the HW mutes to shut down amplifiers and does an analog shutdown of the codec. That might improve power consumption during sleep on a number of machines. Signed-off-by: Benjamin Herrenschmidt <> Signed-off-by: Andrew Morton <> Signed-off-by: Linus Torvalds <>
