2026-05-10T15:31:34+00:00

AMD Elan support was removed from the upstream kernel with commit 8b793a92d862 ("x86/cpu: Remove M486/M486SX/ELAN support"). Its watchdog driver can no longer be enabled except for test builds. Remove it. Signed-off-by: Guenter Roeck

watchdog: Prefix WDT with ICS for clarity

2026-05-10T15:31:34+00:00

`wdt.rst` is only about the Watchdog from "Industrial Computer Source" (ICS). Change the title and rename the file to better express this. Add missing SPDX license identifier `GPL-2.0-or-later` same as code to silence `checkpatch`. Fix wrong link to sample driver in drivers/watchdog/smsc37b787_wdt.c.

watchdog: remove driver for integrated WDT of ZFx86 486-based SoC

2026-05-03T15:33:06+00:00

The machzwd driver supports the integrated watchdog of the ZF Micro ZFx86 SoC, which contains a 486-compatible core [1]. Since 486 support was removed in commit 8b793a92d862 ("x86/cpu: Remove M486/M486SX/ELAN support"), the driver is no longer useful, Remove it.
