Subject: arm64: zynqmp: List lpd watchdog in dtsi
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=6475f1405b80dafa0e87e9bdb4f8a761e59e7786;p=thirdparty%2Fu-boot.git

arm64: zynqmp: List lpd watchdog in dtsi

There are use cases where lpd watchdog can be configured for APU use. By
design this IP should be listed in zynqmp.dtsi to make sure that node is
properly enabled by DTG.
