Resetting the watchdog timer on CIR interrupts or on game port interrupts is not not supported on recent chips, and doesn't really tell if the system is stable. On top of that, at least the bit to enable resetting the watchdog through the game port is used differently on recent chips. Drop resetting the watchdog on CIR or game port interrupts to simplify the code. Signed-off-by:

The dw_wdt has an external reset line, that can keep the device in reset and therefore rendering it useless and also is the only way of stopping the watchdog once it was started. Get the reset lines for this core from the devicetree. As these lines are optional, use devm_reset_control_get_optional_shared. If the reset line is not specified in the devicetree, the reset framework will just skip deasserting and continue. This way all users of the driver will continue to function without any harm, even if the reset line is not specified in the devicetree. Signed-off-by:

On some systems its desirable to have watchdog reboot the system when it does not come up fast enough. This adds a kernel parameter to disable the auto-update of watchdog before userspace takes over and a kernel option to set the default. The info messages were added to shorten error searching on misconfigured systems. Signed-off-by:

Add binding information for DA9062 and DA9061 watchdog. Example bindings for both DA9062 and DA9061 devices are added. For the DA9061 device, a fallback compatible line is added as a valid combination of compatible strings. The original binding for DA9062 (only) used to reside inside the Documentation/devicetree/bindings/mfd/da9062.txt MFD document. The da9062-watchdog section was deleted in that file and replaced with a link to the new DA9061/62 binding information stored in this patch. Acked-by:

The infrastructure now also supports generating additional heartbeats if the maximum hardware timeout is smaller than or close to the configured timeout.

Because suspending to RAM may lose the register values, they are restored on resume. This is currently done unconditionally because there is currently no way to know (from the driver) whether they have really been lost or are still valid. Writing MR also pings the watchdog and this may not be what is expected so add a comment explaining why it happens. Signed-off-by:

This fixes a problem with reading files larger than 2GB from a UFS-2 file system: https://bugzilla.kernel.org/show_bug.cgi?id=195721 The incorrect UFS s_maxsize limit became a problem as of commit c2a9737f ("vfs,mm: fix a dead loop in truncate_inode_pages_range()") which started using s_maxbytes to avoid a page index overflow in do_generic_file_read(). That caused files to be truncated on UFS-2 file systems because the default maximum file size is 2GB (MAX_NON_LFS) and UFS didn't update it. Here I simply increase the default to a common value used by other file systems.
