![]() Since commit 623d96e89aca6("imx: wdog: correct wcr register settings") issuing a 'reset' command causes the system to hang. Unlike i.MX and Vybrid, the watchdog controller on LS102x is big-endian. This means that the watchdog on LS1021 has been working by accident as it does not use the big-endian accessors in drivers/watchdog/imx_watchdog.c. Commit 623d96e89aca6("imx: wdog: correct wcr register settings") only revelead the endianness problem on LS102x. In order to fix the reset hang, introduce a reset_cpu() implementation that is specific for ls102x, which accesses the watchdog WCR register in big-endian format. All that is required to reset LS102x is to clear the SRS bit. This approach is a temporary workaround to avoid a regression for LS102x in the 2015.10 release. The proper fix is to make the watchdog driver endian-aware, so that it can work for i.MX, Vybrid and LS102x.
