The remove function in the PL022 driver cannot abort the remove function any way, so restructure the code so as not to make that assumption. Remove will now proceed no matter whether it can stop the transfer queue or not.

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 only difference between SPI_IMX_VER_0_7 and SPI_IMX_VER_0_4 is .config function. 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. A couple of redundant macros, MX3_CSPISTAT and MX3_CSPISTAT_RR, together with the useless type SPI_IMX_VER_0_5 also get cleaned up.

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.

The existing macro fails for following scenarios. 1) S5P64X0 channel 1 2) S5PV210 channel 1 The FIFO data level supported in the above SoCs either 64 or 256 bytes depending on the channel. Because of this the TX_DONE is the 25 bit in the status register. The existing macro works for the following scenarios 1) S3C6410 all channels 2) S5PC100 all channels The FIFO data level supported in the above SoCs 64 bytes on all the channels. Because of this the TX_DONE is the 21 bit in the status register. So when we use the existing macro for the non-working SoCs it is not anding with the TX_DONE bit for transmission status check.

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.

The default bits per word setting should be 8 bits, but since most of our devices have been explicitly setting this up, we didn't notice when the default stopped working. At the moment, any default transfers without an explicit bit size setting error out with: bfin-spi bfin-spi.0: transfer: unsupported bits_per_word So in the transfer logic, have a bits_per_word setting of 0 fall into the 8 bit transfer logic.

The Blackfin SPORT peripheral is a pretty flexible device. With enough coaching, we can make it generate SPI compatible waveforms. This is desirable as the SPORT can run at much higher clock frequencies than the dedicated on-chip SPI peripheral, and it can do full duplex DMA. It also opens up the possibility of multiple SPI buses in case someone wants to dedicate a whole bus to a specific part that does not play well with others.
