[PATCH v2 0/6] can: tcan4x5x: Introduce tcan4552/4553
From: Markus Schneider-Pargmann

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.
In v2 I updated the bindings to use tcan4x5x always as a fallback. The
driver now uses the first more specific binding if available. If the
given binding does not match the chip that is present, a warning is
printed and the correct driver data is loaded instead.
Based on v6.4-rc1.
Best,
Markus
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
