From: Suman Anna Date: Thu, 9 Jul 2020 23:19:54 +0000 (-0500) Subject: ARM: dts: omap5-uevm: Add watchdog timers for IPU and DSP X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e94828c17c99319ea59837d4a3eb18fe7045e0b4;p=linux.git ARM: dts: omap5-uevm: Add watchdog timers for IPU and DSP The watchdog timers have been added for the IPU and DSP remoteproc devices for the OMAP5 uEVM board. The following timers (same as the timers on OMAP4 Panda boards) are used as the watchdog timers, DSP : GPT6 IPU : GPT9 & GPT11 (one for each Cortex-M4 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.
