2016-01-11watchdog: Add support for creating driver specific sysfs attributesGuenter Roeck
The Zodiac watchdog driver attaches additional sysfs attributes to the watchdog device. This has a number of problems: The watchdog device lifetime differs from the driver lifetime, and the device structure should therefore not be accessed from drivers. Also, creating sysfs attributes after driver registration results in a potential race condition if user space expects the attributes to exist but they don't exist yet. Add support for creating driver specific sysfs attributes to the watchdog core to solve the problems.

2015-12-29watchdog: Separate and maintain variables based on variable lifetimeGuenter Roeck
All variables required by the watchdog core to manage a watchdog are currently stored in struct watchdog_device. The lifetime of those variables is determined by the watchdog driver. However, the lifetime of variables used by the watchdog core differs from the lifetime of struct watchdog_device. To remedy this situation, watchdog drivers can implement ref and unref callbacks, to be used by the watchdog core to lock struct watchdog_device in memory. While this solves the immediate problem, it depends on watchdog drivers to actually implement the ref/unref callbacks. This is error prone, often not implemented in the first place, or not implemented correctly. To solve the problem without requiring driver support, split the variables in struct watchdog_device into two data structures - one for variables associated with the watchdog driver, one for variables associated with the watchdog core. With this approach, the watchdog core can keep track of its variable lifetime and no longer depends on ref/unref callbacks in the driver. As a side effect, some of the variables originally in struct watchdog_driver are now private to the watchdog core and no longer visible in watchdog drivers. As a side effect of the changes made, an ioctl will now always fail with -ENODEV after a watchdog device was unregistered with the character device still open. Previously, it would only fail with -ENODEV in some situations. Also, ioctl operations are now atomic from driver perspective. With this change, it is now guaranteed that the driver will not unregister a watchdog between a timeout change and the subsequent ping. The 'ref' and 'unref' callbacks in struct watchdog_driver are no longer used and marked as deprecated.

2015-12-29watchdog: Create watchdog device in watchdog_dev.cGuenter Roeck
The watchdog character device is currently created in watchdog_dev.c, and the watchdog device in watchdog_core.c. This results in cross-dependencies, since device creation needs to know the watchdog character device number as well as the watchdog class, both of which reside in watchdog_dev.c. Create the watchdog device in watchdog_dev.c to simplify the code. Inspired by earlier patch set from Damien Riegel.

This watchdog is instantiated in a FPGA that is memory mapped. It is made of only one register, called the feed register. Writing to this register will re-arm the watchdog for a given time (and enable it if it was disable). It can be disabled by writing a special value into it. It is part of a syscon block, and the watchdog register offset in this block varies from board to board. This offset is passed in the syscon property after the phandle to the syscon node.

On 64bit platforms, "(1 << (16 + top)) / clk_get_rate(dw_wdt.clk)" is sign-extended to 64bit then converted to unsigned 64bit, finally divide the clk rate. If the top is the maximum TOP i.e 15, "(1 << (16 +15))" will be sign-extended to 0xffffffff80000000, then converted to unsigned 0xffffffff80000000, which is a huge number, thus the final result is wrong. We fix this issue by giving usigned value(1U in this case) at first. Let's assume clk rate is 25MHZ, Before the patch: dw_wdt_top_in_seconds(15) = -864612050 After the patch: dw_wdt_top_in_seconds(15) = 85 Signed-off-by: Jisheng Zhang <jszhang@marvell.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

2015-12-13watchdog: core: add reboot notifier supportDamien Riegel
Many watchdog drivers register a reboot notifier in order to stop the watchdog on system reboot. Thus we can factorize this code in the watchdog core. For that purpose, a new notifier block is added in watchdog_device for internal use only, as well as a new watchdog_stop_on_reboot helper function. If this helper is called, watchdog core registers the related notifier block and will stop the watchdog when SYS_HALT or SYS_DOWN is received. Since this operation can be critical on some platforms, abort the device registration if the reboot notifier registration fails.
