Subject: arm64: dts: ti: k3-j784s4-j742s2-main-common.dtsi: Refactor watchdog instances for... 
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=61acc4428a7f52e0a13e226ba76f2ce2ca66c065;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: ti: k3-j784s4-j742s2-main-common.dtsi: Refactor watchdog instances for j784s4

Each A72 core has one watchdog instance associated with it. Since j742s2
has 4 A72 cores, the common file should not define 8 watchdog instances.

Refactor the last 4 extra watchdogs from the common file to j784s4
specific file, as j784s4 has 8 A72 cores and thus hardware description
requires 8 watchdog instances.
