[PATCH] dt-bindings: serial: snps-dw-apb-uart: remove N1S binding

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is one of four (quite randomly) added bindings for Renesas RZ/N1S.
Essential bindings like clock support are missing for 8 years. With 6MB
of internal RAM only, N1S is not a prime candidate for running Linux,
unlike the DDR-RAM capable N1D. I could not find any further activity in
upstreaming N1S support, neither for Linux or any other OS. So, remove
these half-baked dangling bindings which are incomplete and look
unprofessional. We can happily add them back if somebody offers complete
support for it. Until then, let's enjoy the easier handling of a single
'const'.

This would render Geert's cleanup unnecessary:
