This patch series updates the GRCAN driver to support the GRCANFD core
from the GRLIB IP core library.

In addition to GRCANFD support, the updates include enhancements for
compatibility with NOEL-V (RISC-V) systems, such as matching drivers
using the 'compatible' identifier and adding support for reading clock
frequency via the common clock framework where available. The series
also includes improvements like functions for configuring
nominal bit-timing and optimizations for DMA operations.

This series also updates the driver documentation and bindings.
The old text binding is converted to YAML, a new vendor prefix
is added to reflect the updated ownership and an entry for the
driver is added to the MAINTAINERS file.
