From: Andre Przywara Date: Thu, 12 Sep 2024 23:15:22 +0000 (+0100) Subject: watchdog: sunxi: add A523 support X-Git-Tag: v2025.07-rc1~10^2~10 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8fb6c9343dbbd980c0945560f69b5a88f2404de7;p=thirdparty%2Fu-boot.git 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.
