Subject: [PATCH 3/3] ACPI / watchdog: Prefer iTCO_wdt always when WDAT table
|
||||
uses RTC SRAM
|
||||
|
||||
After we added quirk for Lenovo Z50-70 it turns out there are at least
|
||||
two more systems where WDAT table includes instructions accessing RTC
|
||||
SRAM. Instead of quirking each system separately, look for such
|
||||
instructions in the table and automatically prefer iTCO_wdt if found.
