[PATCH v4 0/2] Add reaction control in rti
From: Judith Mendez
Date: Mon Jul 21 2025 - 19:57:40 EST
This allows for reaction control in rti driver. Since AM62L SoC [0]
does not have WWD reset output routed to a ESM module like all other
K3 SoC's and has the reset output signal routed to the reset HW block,
add a new compatible for AM62L and configure reset reaction for AM62L
SoC instead of NMI.
This patch has been tested on AM62L EVM [1].
Changes since v3:
- Expected default reaction for watchdog is HW reset line, so check for NMI
and set reaction to NMI if exists, else default to HW reset.
