This patch is to prevent hpwdt from loading on any auxilary iLO devices defined after the initial (or main) iLO device. All auxilary iLO devices will have a subsystem device ID set to 0x1979 in order for hpwdt to differentiate between the two types.

Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource. Move the call to platform_get_resource adjacent to the call to devm_ioremap_resource to make the connection between them more clear.

The bits in BRIDGE_CAUSE are documented as RW0C - read, write 0 to clear. If we read the register, mask off the watchdog bit, and write it back, we're actually clearing every interrupt which wasn't pending at the time we read the register - and that is racy. Fix this to only write ~WATCHDOG_BIT to the register, which means we write as zero only the watchdog bit.

The watchdog infrastructure in Dove is no different from that in Orion5x or Kirkwood, so let's enable it for Dove. The only things missing are a few register settings in Dove's bridge-regs.h. Rather than duplicating the same register bit masks for the RSTOUTn_MASK and BRIDGE_CAUSE registers, move the definitions into the watchdog driver itself.

Interrupt request doesn't use the right API: The TWD watchdog uses a per-cpu interrupt (usually interrupt #30), and the GIC configuration should flag it as such. With this setup, request_irq() should fail, and the right API is request_percpu_irq(), together with enable_percpu_irq()/disable_percpu_irq(). Nothing ensures the userspace ioctl() will end-up kicking the watchdog on the right CPU. There are no users of this driver since a long time and it makes more sense to get rid of it as nobody is looking to fix it. In case somebody wakes up after this has been removed and needs it, please revert this driver and pick these updates (These were never pushed to mainline): http://comments.gmane.org/gmane.linux.ports.arm.kernel/245998Signed-off-by: NViresh Kumar <viresh.kumar@linaro.org> Acked-by: NGuenter Roeck <linux@roeck-us.net> Signed-off-by: NWim Van Sebroeck <wim@iguana.be>

A watchdog device may be stopped from userspace using WDIOC_SETOPTIONS ioctl and flag WDIOS_DISABLECARD. If the device is closed after this operation, watchdog_release() is called and status bits checked for stopping it. Besides, if the device has not been unregistered a critical message "watchdog did not stop!" is printed, although the ioctl may have successfully stopped it already. Without the patch a user application sample code like this will successfully stop the watchdog, but the kernel will output the message "watchdog did not stop!": wd_fd = open("/dev/watchdog", O_RDWR); flags = WDIOS_DISABLECARD; ioctl(wd_fd, WDIOC_SETOPTIONS, &flags); close(wd_fd); Signed-off-by: NHector Palacios <hector.palacios@digi.com> Reviewed-by: NGuenter Roeck <linux@roeck-us.net> Signed-off-by: NWim Van Sebroeck <wim@iguana.be>
