Subject: ARM: ux500: convert Snowball SPI pin reference
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=fd8f9eac9dca386f54dfeff94afd03c84ec72ca1;p=deliverable%2Flinux.git

ARM: ux500: convert Snowball SPI pin reference

The SPI0 block is not at all connected to the AB8500 on the
Snowball: it is connected to the external header. These pins
on the header may also be used for GPIO, but let's assume
that SPI is a probable usecase on the Snowball and mux in the
SPI block and use these for SPI.
