+Subject: [PATCH] ARM: bcm283x: Extend the WDT DT node out to cover the
+ whole PM block. (v4)
+
+It was covering part of the PM block's range, up to the WDT regs.  To
+support the rest of the PM block's functionality, we need the full
+register range plus the AXI Async Bridge regs for PM sequencing.
+
+This doesn't convert any of the consumers over to the new binding yet,
+since we will need to be careful in coordinating our usage of firmware
+services that might power domains on and off versus the bcm2835-pm
+driver's access of those same domains.
