From 8fb6c9343dbbd980c0945560f69b5a88f2404de7 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Fri, 13 Sep 2024 00:15:22 +0100 Subject: [PATCH] watchdog: sunxi: add A523 support The Allwinner A523 SoC moved the watchdog into a separate MMIO frame, and also shifted the registers a bit: the control, config, and mode register are located four bytes earlier. Add the new compatible string, and connect it to the new struct describing the new register layout.
