From: Jimmy Assarsson <extja@xxxxxxxxxx> This patch series will add support for the Kvaser USB hydra family. Patches 01-04 and 09-10 contains minor fixes/improvements for the current driver. Patch "can: kvaser_usb: Add driver name to printouts" from the first version of this patch series is replaced by patches 05-08. See discussion with Marc here https://marc.info/?t=152472147500003&r=1&w=2 Patch 11 (Split driver into...) will split the current driver into kvaser_usb.h kvaser_usb_core.c kvaser_usb_leaf.c. Where family common functionality is kept in kvaser_usb_core.c and leaf specific functionality is moved to kvaser_usb_leaf.c. Patch 12 adds support for the hydra family. The USB communication concept is similar to the leaf and USBcanII driver. The driver will send and receive hydra commands, where a command number is used to identify the command. However, for hydra devices it is possible to address to which thread in firmware a certain command shall be sent to. And vice versa it is possible to determine which firmware thread sent the command. The firmware threads are denoted hydra entity (HE). Firmware will allocate HE addresses for each HE dynamically at boot. Hence, the driver need to enumerate the HE addresses.
