From f1c4a33fb83eedfa9cdd32867c4d445fa8e74555 Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Thu, 9 Jul 2020 18:19:53 -0500 Subject: [PATCH] ARM: dts: omap4-panda-common: Add watchdog timers for IPU and DSP The watchdog timers have been added for the IPU and DSP remoteproc devices on all the OMAP4-based Panda boards. The following timers are used as the watchdog timers, DSP : GPT6 IPU : GPT9 & GPT11 (one for each Cortex-M3 core) The MPU-side drivers will use this data to initialize the watchdog timers, and listen for any watchdog triggers. The BIOS-side code needs to configure and refresh these timers properly to not throw a watchdog error. These timers can be changed or removed as per the system integration needs, alongside appropriate equivalent changes on the firmware side.
