arm64: dts: ti: k3-j784s4-main: Add the main domain watchdog instances
Browse files Browse the repository at this point in the history 
There are totally 19 instances of watchdog module. One each for the
8 A72 cores, one each for the 4 C7x cores, 1 for the GPU, 1 each
for the 6 R5F cores in the main domain. The non-A72 instances are
coupled with the R5Fs, C7x & GPU instances. Keeping them as reserved as
they are not used by A72.
