[PATCH v1 10/10] imx: Remove hardcoded watchdog base address macros

alice.guo at oss.nxp.com alice.guo at oss.nxp.com
Tue Mar 10 08:53:44 CET 2026 

From: Alice Guo <alice.guo at nxp.com>

The watchdog base addresses are now obtained from the devicetree via
the imx_wdog_alias_to_addr() function. Remove the hardcoded macro
definitions as they are no longer needed.
