2011-09-21spi: spi-dw: fix all sparse warningsH Hartley Sweeten1-44/+53
The dw_{read,write}[lw] macros produce sparse warnings everytime they are used. The "read" ones cause: warning: cast removes address space of expression warning: incorrect type in argument 1 (different address spaces) expected void const volatile [noderef] <asn:2>*addr got unsigned int *<noident> And the "write" ones: warning: cast removes address space of expression warning: incorrect type in argument 2 (different address spaces) expected void volatile [noderef] <asn:2>*addr got unsigned int *<noident> Fix this by removing struct dw_spi_reg and converting all the register offsets to #defines. Then convert the macros into inlined functions so that proper type checking can occur. While here, also fix the three sparse warnings in spi-dw-mid.c due to the return value of ioremap_nocache being stored in a u32 * not a void __iomem *. With these changes the spi-dw* files all build with no sparse warnings.

2011-06-06spi: reorganize driversGrant Likely1-0/+232
Sort the SPI makefile and enforce the naming convention spi_*.c for spi drivers. This change also rolls the contents of atmel_spi.h into the .c file since there is only one user of that particular include file. v2: - Use 'spi-' prefix instead of 'spi_' to match what seems to be be the predominant pattern for subsystem prefixes. - Clean up filenames in Kconfig and header comment blocks Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Wolfram Sang <w.sang@pengutronix.de> Acked-by: Linus Walleij <linus.walleij@linaro.org>
