kernel/linux.git/drivers/net/can/esd, branch v6.18.22Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v6.18.222025-10-20T15:17:59+00:00can: esd: acc_start_xmit(): use can_dev_dropped_skb() instead of can_dropped_invalid_skb()2025-10-20T15:17:59+00:00Marc Kleine-Buddemkl@pengutronix.de2025-10-17T14:28:49+00:00urn:sha1:0bee15a5caf36fe513fdeee07fd4f0331e61c064
In addition to can_dropped_invalid_skb(), the helper function
can_dev_dropped_skb() checks whether the device is in listen-only mode and
discards the skb accordingly.
Replace can_dropped_invalid_skb() by can_dev_dropped_skb() to also drop
skbs in for listen-only mode.

can: esd_402_pci: Add support for one-shot mode2024-08-05T15:32:00+00:00Stefan Mätjestefan.maetje@esd.eu2024-07-17T21:44:09+00:00urn:sha1:c20ff3e0d9ebdc9f7fd84b8c59c2cba9442324c3
This patch adds support for one-shot mode. In this mode there happens no
automatic retransmission in the case of an arbitration lost error or on
any bus error.

can: esd_402_pci: Rename esdACC CTRL register macros2024-08-05T15:32:00+00:00Stefan Mätjestefan.maetje@esd.eu2024-07-17T21:44:08+00:00urn:sha1:3e6cb3f2fb4344db54b35601effc1ff46ebd9698
Rename macros to use for esdACC CTRL register access to match the
internal documentation and to make the macro prefix consistent.
- ACC_CORE_OF_CTRL_MODE -> ACC_CORE_OF_CTRL
Makes the name match the documentation.
- ACC_REG_CONTROL_MASK_MODE_ -> ACC_REG_CTRL_MASK_
ACC_REG_CONTROL_MASK_ -> ACC_REG_CTRL_MASK_
Makes the prefix consistent for macros describing masks in the same
register (CTRL).

can: esd: add support for esd GmbH PCIe/402 CAN interface family2024-02-12T15:58:30+00:00Stefan Mätjestefan.maetje@esd.eu2023-11-22T16:02:11+00:00urn:sha1:9721866f07e108f892c15ae0c03059e5221b5594
This patch adds support for the PCI based PCIe/402 CAN interface family
from esd GmbH that is available with various form factors
(https://esd.eu/en/products/402-series-can-interfaces).
All boards utilize a FPGA based CAN controller solution developed
by esd (esdACC). For more information on the esdACC see
https://esd.eu/en/products/esdacc.
This driver detects all available CAN interface board variants of
the family but atm. operates the CAN-FD capable devices in
Classic-CAN mode only! A later patch will introduce the CAN-FD
functionality in this driver.
