From eb4c9909dc49f742bdbb9e5d411a4ac1df1cb6d6 Mon Sep 17 00:00:00 2001 From: Keerthy Date: Sun, 8 Oct 2023 10:16:56 +0530 Subject: arm64: dts: ti: k3-j721s2-main: Add the main domain watchdog instances There are totally 9 instances of watchdog module. One each for the 2 A72 cores, one each for the 2 C7x cores, 1 for the GPU, 1 each for the 4 R5F cores in the main domain. Keeping only the A72 instances enabled and reserving the rest by default as they will be used by their respective firmware.
