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