Well, actually I thought that suspend for h1940 and rx3000 works without these tricks... Ok, I'll make it generic for s3c2442 CPU. -------------- next part -------------- A non-text attachment was scrubbed...

Ok, I'll make it generic for s3c2442 CPU. The h1940 is a s3c2410 and all the boot pins on it are specific function for boot. No idea if the rx3xxx series use the upper EINT lines for anything. Anyway, please include the s3c2440 in this change as I belive it also has the saem note. -- Ben Q: What's a light-year?

Almost all drivers for this machine are included in mainline kernel, and port only lacks battery, LED, WiFi and sound support, they will be added later. v2: removed unnecessary mappings use loop for gpio pin configuration fix key table formating WARN_ON() the result of gpio_request() ^ permalink raw reply [flat|nested] 5+ messages in thread
