This series brings two small improvements to the w83627hf_wdt driver. The first patch adds support for the Nuvoton NCT6126 Super I/O chip. The NCT6126 is compatible with the existing driver but requires reading the full 16-bit chip ID, as it shares its high-byte ID with the NCT6116. The second patch improves the handling of watchdogs that are already running when the driver probes. Instead of issuing a single keepalive using the default timeout, it relies on the watchdog core's WDOG_HW_RUNNING support to automatically maintain the watchdog until userspace opens the device. Signed-off-by: Paul Louvel <[email protected]> --- Changes in v3: - Forgot to add case in w83627hf_init() with the chip. Not detected during testing because the BIOS probably configure it anyway on boot. - Link to v2: https://patch.msgid.link/[email protected] Changes in v2: - Small mistake in the first patch. The NCT6116_ID macro is redefined. Fix it.
