OMAP3 PM: Adding counters for power domain logic off and mem off during retention.
This patch adds counters to keep track of whether the powerdomain logic or software controllable memory banks are turned off when the power domain enters retention. During power domain retention if logic gets turned off, the scenario is known as Open Switch Retention. Also during retention s/w controllable memory banks of a power domain can be chosen to be kept in retention or off. This patch adds one counter per powerdomain to track the power domain logic state during retention. Number of memory bank state counters added depends on the number of software controllable memory banks of the powerdomain. To view these counters do cat ../debug/pm_debug/count Signed-off-by: Thara Gopinath <thara@ti.com> [paul@pwsan.com: conditional expressions simplified; counter increment code moved to its own function] Signed-off-by: Paul Walmsley <paul@pwsan.com>
