From bf3af54732bea5894ccc2cbde3ab566f0af7da56 Mon Sep 17 00:00:00 2001 From: Wolfgang Grandegger Date: Thu, 7 Jan 2010 09:43:07 +0000 Subject: can: mscan-mpc5xxx: add support for the MPC512x processor The main differences compared to the MSCAN on the MPC5200 are: - More flexibility in choosing the CAN source clock and frequency: Three different clock sources can be selected: "ip", "ref" or "sys". For the latter two, a clock divider can be defined as well. If the clock source is not specified by the device tree, we first try to find an optimal CAN source clock based on the system clock. If that is not possible, the reference clock will be used. - The behavior of bus-off recovery is configurable: To comply with the usual handling of Socket-CAN bus-off recovery, "recovery on request" is selected (instead of automatic recovery). Note that only MPC5121 Rev. 2 and later is supported. Signed-off-by: Wolfgang Grandegger Reviewed-by: Wolfram Sang Signed-off-by: David S.
