These patches extend the ems_usb.c driver to support both devices, the
classic CAN CPC-USB/ARM7 and the CAN FD CPC-USB/FD. Also support for
the listen only mode for CPC-USB/ARM7 was implemented. Most issues given
by checkpatch.pl were resolved.
Gerhard Uttenthaler (17):
can: ems_usb: Fixed warnings given by checkpatch.pl and fixed some
outdated comments
can: ems_usb: Added defines and product id needed for CPC-USB/FD
can: ems_usb: Added CAN FD message representation
can: ems_usb: Added struct used for CAN FD initialization
can: ems_usb: Replace constant define RX_BUFFER_SIZE by variable
bulk_rd_buf_size, because this will have different values for
CPC-USB/ARM7 and CPC-USB/FD. For the same reason added a function
pointer ems_usb_write_mode. In device probe function added a switch
statement to select between CPC-USB/ARM7 and CPC-USB/FD and
rearranged initialization sequence accordingly.
can: ems_usb: Added listen only mode for CPC-USB/ARM7 and moved
evaluation of can.ctrlmode from set_bittiming routine to
ems_usb_write_mode_arm7 routine. Wrapped a long line.
can: ems_usb: Added CPC_ClearCmdQueue routine to get access to the
interface even it is flooded with messages which cannot successfully
be sent. Set timestamp to 0 in ems_usb_control_cmd.
can: ems_usb: Modified ems_usb_read_bulk_callback to be able to handle
also CPC-USB/FD
can: ems_usb: For CPC-USB/FD added clock definitions, bittiming
constants, set_bittiming functions, bittiming init function and add
all that to probe function
can: ems_usb: Added receive routine for CAN FD messages and its call
in ems_usb_read_bulk_callback
can: ems_usb: Added ems_usb_write_mode_fd and its call in device probe
routine. Fixed indentation.
can: ems_usb: In ems_usb_start_xmit send only bytes with valid content
to interface and not the complete buffer. Set first four bytes of
buffer to 0. Wrapped long lines.
can: ems_usb: Rearrange code in ems_usb_start_xmit to check with
can_is_canfd_skb for CAN FD frames.
can: ems_usb: Added code to handle CAN FD frames in ems_usb_start_xmit
can: ems_usb: In CAN error handling routine checking which CAN
controller type is issuing the error
can: ems_usb: Added error handling part for CPC-USB/FD. Get some
structures packed
can: ems_usb: Made another struct packed. Enable CPC-USB/FD by adding
it to the drivers device table
