From 6e4a7eaf7d6c9aedafa19aa57553ae44dba5ca0d Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 18 Dec 2021 11:27:29 -0700 Subject: [PATCH] timer: Add a migration message Some boards still use the old timer mechanism. Set a deadline for them to update to driver model. Point to some examples as well. This needs a bit of a strange rule to avoid an error on some boards.
