Hi everyone,

This series introduces two new chips tcan-4552 and tcan-4553. The
generic driver works in general but needs a few small changes. These are
caused by the removal of wake and state pins.

v3 removes the check of the devicetree compatible and completely relies
on the ID2 register.

Based on v6.5-rc1.

Best,
Markus

Changes in v3:
- Rebased to v6.5-rc1
- Removed devicetree compatible check in tcan driver. The device version
  is now unconditionally detected using the ID2 register

Changes in v2:
- Update the binding documentation to specify tcan4552 and tcan4553 with
  the tcan4x5x as fallback
- Update the driver to use auto detection as well. If compatible differs
  from the ID2 register, use the ID2 register and print a warning.
- Small style changes
