Subject: ARM: 8246/2: pcmcia: sa1111: provide device clock
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b02cba8693fca6bd9166dd541f6a61cd82f6e231;p=linux-beck.git

ARM: 8246/2: pcmcia: sa1111: provide device clock

Both pxa2xx (long ago) and sa1100 (now) make use of clock device to get
the cpu speed. Make sa1111 glue code provide clock to platform layer.
