Subject: imx_watchdog: Do not assert WDOG_B on watchdog init
X-Git-Tag: v2016.11-rc2~19^2~45
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=9eeab572113b2978d42cbb32886a1e90434bf07c;p=u-boot

imx_watchdog: Do not assert WDOG_B on watchdog init

Currently the driver asserts WDOG_B by clearing WCR_WDA bit when
enabling the watchdog. Do not clear WCR_WDA.
