Subject: imx_watchdog: do not soft-reset while watchdog init
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=723ec69a6b7eeb3e89d35dcf8fd223702ace6125;p=project%2Fbcm63xx%2Fu-boot.git

imx_watchdog: do not soft-reset while watchdog init

Currently the driver clears WCR_SRS bit when enabling
the watchdog and this causes a software reset. Do not
clear WCR_SRS.
