From f532727d16ebd3f8f9464aa503a1990f2f3b3211 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Sat, 3 Oct 2015 14:20:59 -0300 Subject: imx_watchdog: Add a header file for watchdog registers Create fsl_wdog.h to store the watchdog registers and bit fields. This can be useful when accesses to the watchdog block are made from other parts, such as arch/arm/ cpu code.
