From d44d6e021301b6a8d95bf6a92e8aae640de2770a Mon Sep 17 00:00:00 2001 From: Bich HEMON Date: Thu, 15 Nov 2018 08:52:29 +0000 Subject: [PATCH] ARM: dts: stm32: change CAN RAM mapping on stm32mp157c Split the 10Kbytes CAN message RAM to be able to use simultaneously FDCAN1 and FDCAN2 instances. First 5Kbytes are allocated to FDCAN1 and last 5Kbytes are used for FDCAN2. To do so, set the offset to 0x1400 in mram-cfg for FDCAN2.
