      spi: remove completely broken Tegra driver · 536a53a3
      Stephen Warren authored 
      
The current SPI driver has many issues. Examples are:

* Segfaulting on most transfers due to expecting all transfers to have
  both RX and TX buffers.
* Hanging on TX transfers since the whole driver flow is driven by RX
  DMA completion, but the HW is only told to enable RX for RX transfers.
* Use of clk_disable_unprepare() from atomic context.
* Once those and other minor issues are fixed, the driver still doesn't
  actually work.
* The driver also implements a deprecated API to the SPI core.

For this reason, simply remove the driver completely. This has two
advantages:

1) This will remove the last use of Tegra's <mach/dma.h>, which will
   allow that file to be removed, which is required for single zImage
   work.

2) The downstream driver is significaly different from the current
   code. I believe a patch to re-add the downstream driver (with
   appropriate cleanup) will be much simpler to review if it's a new
   file rather than randomly interspered with essentially unrelated
   existing code.

      ARM: S3C24XX: change the ARCH_S3C2410 to ARCH_S3C24XX · b130d5c2
      Kukjin Kim authored 
      
This patch changes the ARCH name to "ARCH_S3C24XX" for Samsung
S3C2410, S3C2412, S3C2413, S3C2416, S3C2440, S3C2442, S3C2443,
and S3C2450 SoCs so that we can merge the mach-xxx directories
and plat-s3c24xx dir. to just one mach-s3c24xx for them.

I think this should be sent to upstream via samsung tree because
this touches many samsung stuff.

      spi/imx: use soc name in spi device type naming scheme · 04ee5854
      Shawn Guo authored 
      
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.

      spi/imx: merge type SPI_IMX_VER_0_7 into SPI_IMX_VER_0_4 · 2a64a90a
      Shawn Guo authored 
      
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.
