From a62fc7ff903c1620c0536b6a549d6cf044f17023 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Thu, 1 Oct 2020 11:11:29 +0200 Subject: dt-bindings: can: flexcan: list supported processors The compatible is a pattern match. Explicitly list all possible values. Also mention that the ls1028ar1 must be followed by lx2160ar1.

This means the 4th and 5th value of the property "fsl,stop-mode" isn't used anymore. It will be removed from the driver in the next patch, so remove it from the binding documentation.
