[v2,0/4] CAST Controller Area Network driver support

Message

Hal Feng Sept. 22, 2024, 2:51 p.m. UTC

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.
