DA830: fix SPI1 base address
Browse files Browse the repository at this point in the history
Commit 54ce688 (davinci: da8xx: add spi
resources and registration routine) wrongly assumed that SPI1 is mapped at
the same address on DA830/OMAP-L137 and DA850/OMAP-L138; actually, the base
address was valid only for the latter SoC. Teach the code to pass the correct
SPI1 memory resource for both SoCs...
