Subject: arm64: dts: renesas: r9a08g046: Add wdt device node
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=8e46bc6370d08a21cc43bb747aef8ffae45df7d7;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: renesas: r9a08g046: Add wdt device node

The RZ/G3L SOC has 3 watchdog timer channels:
  - channel0 (wdt0) for Cortex-A55-CPU Non-Secure,
  - channel1 (wdt1) for Cortex-A55 CPU Secure,
  - channel2 (wdt2) for Cortex-M33 CPU.

Add wdt0 node to RZ/G3L ("R9A08G046") SoC DTSI.
