From: Roman Fietze roman.fietze@telemotive.de Date: Wed, 11 Jul 2018 15:36:14 +0200 Subject: [PATCH] can: m_can.c: fix setup of CCCR register: clear CCCR NISO bit before checking can.ctrlmode
Inside m_can_chip_config(), when setting up the new value of the CCCR, the CCCR_NISO bit is not cleared like the others, CCCR_TEST, CCCR_MON, CCCR_BRSE and CCCR_FDOE, before checking the can.ctrlmode bits for CAN_CTRLMODE_FD_NON_ISO. ...
This patch cannot be applied to the kernel version 4.9, because the M-CAN driver in this kernel does not support M-CAN controllers with V3.1.x or V3.2.x, only 3.0.x is supported.
Support for newer versions than 3.0.x was added in commit b03cfc5bb0e11f88988e5da2805867e468d03ca1, somewhere between v4.11-rc7 and v4.12-rc1.
Great, thanks for letting me know.
