Hi Arnd and Darshana,
Sorry for somehow top-posting, but let me provide some context to what
follows. While pushing a set of patches for ISL 12057 RTC chip, I tried
and continue what had been started by Philip Zabel (7a6540ca856a,
"ARM: mvebu: Change vendor prefix for Intersil Corporation to isil")
in one of the patches (see below) by switching the vendor prefix for
Intersil from isl to isil. This specific patch was handled by Andrew via
his -mm tree and now conflicts with what you pushed upstream.
I do not have a strong advice on what is better and will follow what you
decide by providing an updated patch to Andrew but:
- your changes somehow revert what has been done by philip
- three .dts files (those updated by Philip for isil) now have a deprecated prefix
- we now have both isil and isl in vendor-prefixes.txt
- FWIW, isil is the nasdaq symbol
Cheers,
a+
