From: Alice Guo <[email protected]> Introduce wdog3, wdog4, and wdog5 aliases and mark the corresponding nodes with bootph-all to enable imx_wdog_alias_to_addr() to resolve the watchdog register base addresses via the device tree.
When CONFIG_OF_UPSTREAM is disabled, upstream device tree files are not used. Therefore, wdog4 and wdog5 nodes need to be added directly to arch/arm/dts/imx93.dtsi.
