dt-bindings: serial: lantiq: Convert to YAML & add support for new SoC
Subsystems (2)
v3 cover dt-bindings: serial: lantiq: Convert to YAML & add support for new SoC
There is a new product which reuses Lantiq serial controller IP. Patch 1 in this series converts existing lantiq dt bindings to YAML schema and Patch 2 updates it to support newer product.
These patches are baselined upon Linux 5.3-rc4 at below Git tree:git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git
v3:
* Use compatible name for filename.
* Use if/then schema to describe a property which is different for each compatibles.
* Address other review concerns about YAML format.
v2:
* Update license to GPL-2.0-only.
* Fix trailing whitespace error.
