7 title: Texas Instruments K3 SoC Watchdog Timer
10   - Tero Kristo <t-kristo@ti.com>
13   The TI K3 SoC watchdog timer is implemented via the RTI (Real Time
14   Interrupt) IP module. This timer adds a support for windowed watchdog
15   mode, which will signal an error if it is pinged outside the watchdog
