This patch adds the flag .pwrsts_logic_ret info for the core power domain in the associated powerdomain structure. This flag specifies the states core domain logic can hit in event of the domain entering retention. Signed-off-by: Thara Gopinath <thara@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
