tristate "Support for Freescale MSCAN based chips"
---help---
The Motorola Scalable Controller Area Network (MSCAN) definition
is based on the MSCAN12 definition which is the specific
implementation of the Motorola Scalable CAN concept targeted for
the Motorola MC68HC12 Microcontroller Family.

tristate "Freescale MPC5xxx onboard CAN controller"
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 <wg@denx.de> Reviewed-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: David S.
