This patch changes the ARCH name to "ARCH_S3C24XX" for Samsung S3C2410, S3C2412, S3C2413, S3C2416, S3C2440, S3C2442, S3C2443, and S3C2450 SoCs so that we can merge the mach-xxx directories and plat-s3c24xx dir. to just one mach-s3c24xx for them.

2012-02-29watchdog: fix GETTIMEOUT ioctl in booke_wdtDmitry Artamonow
Commit dcfb748422 ([WATCHDOG] fix book E watchdog to take WDIOC_SETTIMEOUT arg in seconds) fixed SETTIMEOUT ioctl to use seconds as a parameter instead of some hardware-specific "period", but missed to apply similar changes to GETTIMEOUT, so it still returns "period" value. Let's fix it! Also, while at it, make SETTIMEOUT ioctl return real timeout value as it should do according to the documentation.

2011-12-27watchdog: iTCO_wdt.c - problems with newer hardware due to SMI clearing (part 2)Wim Van Sebroeck
Redhat Bugzilla: Bug 727875 - TCO_EN bit is disabled by TCO driver The previous patch breaks reset watchdog behaviour on the older hardware. It is therefor better to make sure that the behaviour for older hardware (<=ICH5 or 6300ESB) is preserved and that the behaviour for newer hardware is changed. We therefor use the iTCO_version to see if we need the clearing of the SMI_TCO_EN bit in the SMI_EN register. So the new behaviour becomes: turn_SMI_watchdog_clear_off=0 -> Do not turn off SMI clearing watchdog. turn_SMI_watchdog_clear_off=1 -> Turn off SMI clearing watchdog when iTCO_version=1 (ICHO till ICH5 + 6300ESB only) turn_SMI_watchdog_clear_off=2 -> Turn off SMI clearing watchdog.

2011-11-18USB: convert some miscellanies drivers to use module_usb_driver()Greg Kroah-Hartman
This converts the remaining USB drivers in the kernel to use the module_usb_driver() macro which makes the code smaller and a bit simpler. Added bonus is that it removes some unneeded kernel log messages about drivers loading and/or unloading.

2011-11-16watchdog: fix initialisation printout in s3c2410_wdtDmitry Artamonow
Looks like a typo creeped in, and driver prints s3c2410-wdt s3c2410-wdt: watchdog active, reset abled, irq abled instead of s3c2410-wdt s3c2410-wdt: watchdog active, reset enabled, irq enabled Also it may completely disinform about irq status, as it prints "irq enabled" when S3C2410_WTCON_INTEN is in fact 0.
