From: Rob Herring <r...@kernel.org>
We attempt to search for compatible strings which use a variable
token in the documented name such as <chip> or <soc>. While this
was attempted to be handled, it's utterly broken.
The desired forms of matching are:
vendor,<chip>-*
vendor,name<part#>-*
For <chip>, lower case characters and numbers are permitted. For
<part#>, only numeric values are allowed.
With this change, the number of missing compatible strings reported in
arch/arm/boot/dts is reduced from 1071 to 960.
