X-Git-Tag: v2.6.22-rc3~112^2~15
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e903382ceae1dd85e650ffc7e98facdd59cc7a3f;p=linux-2.6

[ARM] 4384/1: S3C2412/13 SPI registers offset correction

Change the SPI Channel 1 register offset in s3c_spi1_resource[], and
s3c2412_dma_mappings[]. Offset has to be 0x100 in s3c2412/13's case.
Also, total SPI memory resource size changed to 0x24 for s3c2412/13.
