From: Pali Rohár Date: Mon, 14 Feb 2022 10:34:25 +0000 (+0100) Subject: watchdog: armada_37xx: Convert to official DT bindings X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=0c4625ac7dab5048b588d55e43ace109246df932;p=u-boot.git watchdog: armada_37xx: Convert to official DT bindings Official DT bindings have only one reg property: watchdog address space. Convert armada-37xx-wdt.c driver to offical DT bindings and access sel_reg register via MVEBU_REGISTER() macro, as its value (required by U-Boot driver) is not in DT yet. In later stage can be driver cleaned to not use it. This change would allow U-Boot to use A3720 watchdog DTS structure from Linux kernel.
