* dmaengine/dma_slave: introduce inline wrappersAlexandre Bounine2012-03-211-2/+2
| | | | | | | | | | Add inline wrappers for device_prep_slave_sg() and device_prep_dma_cyclic() interfaces to hide new parameter from current users of affected interfaces. Convert current users to use new wrappers instead of direct calls. Suggested by Russell King [https://lkml.org/lkml/2012/2/3/269].

* dmaengine: Pass dma_slave_config .device_fc = NULL for all existing usersViresh Kumar2012-02-221-0/+3
| | | | | | | | | | .device_fc is added in struct dma_slave_config recently. All user drivers, which want DMA to be the flow controller must pass this field as false. As earlier driver don't look to use this feature, mark it false for now.

* | spi: spi-dw: fix all sparse warningsH Hartley Sweeten2011-09-211-4/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* spi: reorganize driversGrant Likely2011-06-061-0/+224
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>
