Bug#1051449: linux-image-rt-amd64: Enable "Advantech Embedded Controller Watchdog" support

[Yoann Congal <yoann.congal@smile.fr>]

Package: linux-image-rt-amd64
Version: 6.5.1-1~exp1
Severity: wishlist
X-Debbugs-Cc: yoann.congal@smile.fr

Dear Maintainer,

Please enable "Advantech Embedded Controller Watchdog" support.

This is the config CONFIG_ADVANTECH_EC_WDT. This kind of watchdog is
present on industrial Adantech computers like ECU-579 [1].

Sadly, the driver's KConfig has a dependency bug were it can be compiled
into a non-operational state. We upstreamed the fix (6eb28a38f6478) [2]
and it will be released in v6.6. This fix will have to be backported.

Note: the fix enables ISA_BUS_API which is disabled in current versions.

Thanks!
