2014-10-02spi: dw-mid: change magic numbers to the constantsAndy Shevchenko1-0/+4
Instead of using magic numbers in the code we create a bit map definition of the DMACR register and use it. There is no functional change. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-09-13spi: dw-mid: remove redundant dmac memberAndy Shevchenko1-1/+0
Instead of using that member we prefer to use dma_dev which represents actual struct device of the DMA device. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-09-13spi: dw: remove FSF addressAndy Shevchenko1-3/+3
There is no need to keep FSF address in the head of the file. While here, fix few typos in the header. There is no functional change. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-04-24spi: dw: add support for gpio controlled chip selectBaruch Siach1-5/+11
Also, use this opportunity to let spi_chip_sel() handle chip-select deactivation as well. Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-12-31spi: dw: use managed resourcesBaruch Siach1-3/+1
Migrate mmio code and core driver to managed resources to reduce boilerplate error handling code. Also, handle clk_enable() failure while at it, and drop unused dw_spi iolen field. Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Mark Brown <broonie@linaro.org>

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>
