Dear Fabio,

Unlike i.MX, LS1021 uses big-endian ordering for the watchdog controller, which means we cannot use the little endian accessors.

- writew(WCR_WDE, &wdog->wcr);
I'm sorry, but I fail to understand how writew() can be better than another I/O accessor. Neither of these has the capability to detect the endianess of this specific register interface ?
Best regards,
