From: Hussein Alasadi <alasadi@xxxxxxxx> This patch fixes the setting of the M_CAN_DBTP register contents: - use DBTP_ (the data bitrate macros) instead of NBTP_ which area used for the nominal bitrate - do not overwrite possibly-existing DBTP_TDC flag by ORing reg_btp instead of overwriting Link: https://lore.kernel.org/r/FRYP281MB06140984ABD9994C0AAF7433D1F69@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Fixes: 20779943a080 ("can: m_can: use bits.h macros for all regmasks") Cc: Torin Cooper-Bennun <torin@xxxxxxxxxxxxxxxxxx> Cc: Chandrasekar Ramakrishnan <rcsekar@xxxxxxxxxxx> Signed-off-by: Hussein Alasadi <alasadi@xxxxxxxx> [mkl: update patch description, update indention] Signed-off-by: Marc Kleine-Budde <mkl@xxxxxxxxxxxxxx> --- drivers/net/can/m_can/m_can.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/net/can/m_can/m_can.c b/drivers/net/can/m_can/m_can.c index bba2a449ac70..43bca315a66c 100644 --- a/drivers/net/can/m_can/m_can.c +++ b/drivers/net/can/m_can/m_can.c @@ -1164,10 +1164,10 @@ static int m_can_set_bittiming(struct net_device *dev) FIELD_PREP(TDCR_TDCO_MASK, tdco)); } - reg_btp = FIELD_PREP(NBTP_NBRP_MASK, brp) | - FIELD_PREP(NBTP_NSJW_MASK, sjw) | - FIELD_PREP(NBTP_NTSEG1_MASK, tseg1) | - FIELD_PREP(NBTP_NTSEG2_MASK, tseg2); + reg_btp |= FIELD_PREP(DBTP_DBRP_MASK, brp) | + FIELD_PREP(DBTP_DSJW_MASK, sjw) | + FIELD_PREP(DBTP_DTSEG1_MASK, tseg1) | + FIELD_PREP(DBTP_DTSEG2_MASK, tseg2); m_can_write(cdev, M_CAN_DBTP, reg_btp); } -- 2.30.2
