   4 Subject: [PATCH] ARM: dts: BCM5301X: Add TWD WD Support to DT
   5
   6 Add support for the ARM TWD Watchdog to the bcm5301x device tree.  The
   7 ARM TWD timer allocated the register space for the WDT, so this patch
   8 necessitated shrinking that.  Also, the GIC masks were added for these.
