This patchset adds support for the CAST Controller Area Network Bus Controller (version fd-7x10N00S00) which is used in StarFive JH7110 SoC. Note that the CAN FD license for JH7110 has expired, so JH7110 only supports CAN CC now. Changes since v1: Patch 1: - Add company information in the commit message. Patch 2: - Add description for the hardware. - Move "allOf" stuff down after the property definitions. - Rename compatible names, clock names, reset names and syscon register names. - Rewrite the example. Patch 3: - Reorder all functions for readability. - Simplify register definitions and register access functions. - Improve syscon related code. - Use clk_bulk interface. - Enable the clocks during .ndo_open() and disable during .ndo_stop(). - Use can_put_echo_skb() and can_get_echo_skb(). - Stop the TX queue when entering .ndo_start_xmit() and restart the TX queue after the transmission finished. - Simplify logic and remove redundant code. - Improve coding style. Patch 4: - Update the nodes according to the new dt-bindings.
