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/spi-pl022: calculate_effective_freq() must set rate <= requested rateViresh Kumar2011-09-211-51/+51

Now, if system have spi's rate as 83 MHz, with possible prescaled rates as 83, 41.5, 20.75, 13.83 (as we can prescale with multiples of 2). If user has given rate to be programmed as 22 MHz, then driver programmes it to 41.5 MHz. This looks to be incorrect, as user might have given the upper limit of the device, and we are programming it above it. - Driver finds the first satisfying rate and programmes it, but with other values of scr & cpsdvsr, it is possible to get more closer rate. This patch fixes these two issues, with some reformatting inside the code. This also creates a inline routine to calculate prescaled rate based on spi's rate, cpsdvsr and scr.

Rather than having every driver fiddle about with enabling runtime PM, that's dealt with in the core and instead, drivers just do a put() in their probe and a balancing get() in their remove function to activate runtime PM for the device. As we're dealing with enabling runtime PM in the core, fix up spi-pl022 as it must not enable and disable runtime PM itself anymore.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Software defined version number is not stable enough to be used in device type naming scheme. The patch changes it to use implicit soc name for spi device type definition. In this way, we can easily align the naming scheme with device tree binding, which comes later. It removes fifosize from spi_imx_data and adds devtype there, so that fifosize can be set in an inline function according to devtype. Also, cpu_is_mx can be replaced by inline functions checking devtype.

The patch uses cpu_is_mx35 (to be removed) as the temporary solution to consolidate functions spi_imx0_4_config and spi_imx0_7_config into mx31_config. As a result, type SPI_IMX_VER_0_7 can be merged into SPI_IMX_VER_0_4. It also renames function spi_imx0_4_reset to mx31_reset to keep consistency with other function naming.

| * spi/imx: do not use spi_imx2_3 to name SPI_IMX_VER_2_3 function and macroShawn Guo2011-07-141-53/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | It's confusing to use spi_imx2_3 to name SPI_IMX_VER_2_3 function and macro, as it easily make people think of imx2 and imx3. It's better to use specific soc name just like what other SPI_IMX_VER do. For SPI_IMX_VER_2_3 case, it will be mx51. To distinguish it from CSPI on mx51, mx51_ecspi might be a good choice.

| | | | | | | | | | | | | | | | | | | | | | | | SPI_IMX_VER_0_0 covers i.mx21 and i.mx27. It makes more sense to use mx21 rather than mx27 to name SPI_IMX_VER_0_0 function and macro, since i.mx21 comes out ealier than i.mx27.

| * spi/fsl_spi: fix CPM spi driverHolger Brunck2011-07-051-17/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the freescale spi driver for CPM. Without this patch SPI on CPM failed because cpm_muram_alloc_fixed tries to allocate muram in an preserved area. The error reported was: mpc8xxx_spi f0011a80.spi: can't allocate spi parameter ram mpc8xxx_spi: probe of f0011a80.spi failed with error -12 Now the driver uses of_iomap to get access to this area similar to i2c driver driver in the i2c-cpm.c which has a similar device tree node.
