Hi, This patch simply adds WDT IO resource for Quark within lpc_sch driver. The MFD driver would register 'ie6xx_wdt' platform device and eventually be bound to its platform driver under drivers/watchdog/ie6xx_wdt.c
I have tested this patch on Intel Quark Galileo Gen v2 boad by opening /dev/watchdog0 and confirmed that the board undergo warm reset when time-out.
I can read the debugfs for the driver by following command:- $ cat /sys/kernel/debug/ie6xx_wdt
To modify the time-out value, we use kernel param:- ie6xx_wdt.timeout=<val in second>
To activate warm reset & enable reset, we use kernel param:- ie6xx_wdt.resetmode=0x18
Thank you very much Ong Boon Leong Intel Corp.
