From 9aea35eb98a6560daf85a2ae9cbd482a66e4d076 Mon Sep 17 00:00:00 2001 From: Conor Dooley Date: Fri, 21 Nov 2025 13:42:30 +0000 Subject: [PATCH] dt-bindings: can: mpfs: document resets The CAN cores on Polarfire SoC both have a reset. The platform firmware brings both cores out of reset, but the linux driver must use them during normal operation. The resets should have been made required, but this is one of the things that can happen when the binding is written without driver support.
