This is v3 of the Theobroma Systems CAN/USB adapter driver upstreaming effort.
Featured v2 -> v3 changes: * count error frames as data packets * use canid_t for all can ids * use BIT(x) instead of (1 << x) * use __le16 / __le32 for little-endian fields * add spinlock around context allocation (fixes a possible race) * fix comment style * use WARN_ON return value * fix state logic bug that did not allow return to ERROR_ACTIVE * drop echo_index from context_array (not needed) * rename "tx_contexts" -> "context_array" to prevent confusion * add __func__ to all errors and warnings, and to info where it made sense Jakob Unterwurzacher (1): can: ucan: add driver for Theobroma Systems UCAN devices Documentation/networking/can_ucan_protocol.rst | 315 +++++ Documentation/networking/index.rst | 1 + drivers/net/can/usb/Kconfig | 10 + drivers/net/can/usb/Makefile | 1 + drivers/net/can/usb/ucan.c | 1628 ++++++++++++++++++++++++ 5 files changed, 1955 insertions(+) create mode 100644 Documentation/networking/can_ucan_protocol.rst create mode 100644 drivers/net/can/usb/ucan.c -- 2.11.0 Cc: Martin Elshuber <martin.elshu...@theobroma-systems.com> Cc: Philipp Tomsich <philipp.toms...@theobroma-systems.com> Cc: Wolfgang Grandegger <w...@grandegger.com> Cc: Marc Kleine-Budde <m...@pengutronix.de> Cc: linux-...@vger.kernel.org Cc: linux-kernel@vger.kernel.org
