2009-04-08[WATCHDOG] omap_wdt.c: move probe function to .devinit.textUwe Kleine-König
A pointer to omap_wdt_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

The buffer passed to the ibm,get-system-parameter RTAS call must be in the RMA. To ensure we pass an address in the RMA use rtas_data_buf for the actual RTAS call and then copy the result to value. We can't just make it static because this can be compiled in as a module. Also add the WDRTAS_SP_SPI_LEN so we don't litter '4' throughout the function.

2009-03-25[PATCH 13/13] drivers/watchdog: use USB API functions rather than constantsJulia Lawall
This set of patches introduces calls to the following set of functions: usb_endpoint_dir_in(epd) usb_endpoint_dir_out(epd) usb_endpoint_is_bulk_in(epd) usb_endpoint_is_bulk_out(epd) usb_endpoint_is_int_in(epd) usb_endpoint_is_int_out(epd) usb_endpoint_num(epd) usb_endpoint_type(epd) usb_endpoint_xfer_bulk(epd) usb_endpoint_xfer_control(epd) usb_endpoint_xfer_int(epd) usb_endpoint_xfer_isoc(epd) In some cases, introducing one of these functions is not possible, and it just replaces an explicit integer value by one of the following constants: USB_ENDPOINT_XFER_BULK USB_ENDPOINT_XFER_CONTROL USB_ENDPOINT_XFER_INT USB_ENDPOINT_XFER_ISOC An extract of the semantic patch that makes these changes is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r1@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) == - \(USB_ENDPOINT_XFER_CONTROL\|0\)) + usb_endpoint_xfer_control(epd) @r5@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) == - \(USB_DIR_IN\|0x80\)) + usb_endpoint_dir_in(epd) @inc@ @@ #include <linux/usb.h> @depends on !inc && (r1||r5)@ @@ + #include <linux/usb.h> #include <linux/usb/...> // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

Given it's size of 32Bit, the maximum timeout value ranges from about 21s to 43s, depending on the configured CPU clock speed.

device_driver' This patch fixes the bug reported in http://bugzilla.kernel.org/show_bug.cgi?id=11681. "Lots of device drivers register a 'struct device_driver' with the '.bus' member set to '&platform_bus_type'. This is wrong, since the platform_bus functions expect the 'struct device_driver' to be wrapped up in a 'struct platform_driver' which provides some additional callbacks (like suspend_late, resume_early). The effect may be that platform_suspend_late() uses bogus data outside the device_driver struct as a pointer pointer to the device driver's suspend_late() function or other hard to reproduce failures."(Lothar Wassmann) Signed-off-by: Ming Lei <tom.leiming@gmail.com> Acked-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Acked-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

orion5x_wdt no longer compiled after the changes in commit ebe35aff883496c07248df82c8576c3b6e84bbbe ("Orion: prepare for runtime-determined timer tick rate"). The tick rate define (ORION5X_TCLK) was removed in favor of a runtime detection. The quick fix is to add the define in the watchdog driver. The fix is not correct for all supported orion5x platforms, but since the supported platforms right now are 133 Mhz and 166 Mhz, it won't be _that_ far off. ;-) A fix that uses the runtime-determined timer tick rate will be applied later.

2009-02-14[ARM] 5390/1: AT91: Watchdog fixesAndrew Victor
The recently merged AT91SAM9 watchdog driver uses the AT91SAM9X_WATCHDOG config variable, whereas the original version of the driver (and the platform support code) used AT91SAM9_WATCHDOG. This causes the watchdog platform_device to never be registered, and therefore the driver not to be initialized. This patch: - updates the platform support code to use AT91SAM9X_WATCHDOG. - includes <linux/io.h> to fix compile error (same fix as was applied to at91rm9200_wdt.c) - fixes comment regarding watchdog clock-rates in at91rm9200.
