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.

v4 updates the printks to use '%pe'.

Based on v6.5-rc1.

Best,
Markus

Changes in v4:
- Use printk("... %pe\n", ERR_PTR(ret)) for new printks

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
