+Subject: [PATCH 562/703] soc: bcm: bcm2835-pm: Fix PM_IMAGE_PERI power domain
+ support.
+
+We don't have ASB master/slave regs for this domain, so just skip that
+step.
+
+Signed-off-by: Eric Anholt <eric@anholt.net>
+Fixes: 670c672608a1 ("soc: bcm: bcm2835-pm: Add support for power domains under a new binding.")
