* spi: qup: Depend on ARCH_QCOMPaul Bolle2014-04-081-1/+1
| | | | | | | | | | | | | | Commit 8fc1b0f87d9f ("ARM: qcom: Split Qualcomm support into legacy and multiplatform") removed Kconfig symbol ARCH_MSM_DT. But that commit left one (optional) dependency on ARCH_MSM_DT untouched. Three Kconfig symbols used to depend on ARCH_MSM_DT: ARCH_MSM8X60, ARCH_MSM8960, and ARCH_MSM8974. These three symbols now depend on ARCH_QCOM. So it appears this driver needs to depend on ARCH_QCOM too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The older Allwinner SoCs (A10, A13, A10s and A20) all have the same SPI controller. Unfortunately, this SPI controller, even though quite similar, is significantly different from the recently supported A31 SPI controller (different registers offset, split/merged registers, etc.). Supporting both controllers in a single driver would be unreasonable, hence the addition of a new driver. Like its more recent counterpart, it supports DMA, but the driver only does PIO until we have a dmaengine driver for this platform.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only remaining feature of spi-bitbang used by this driver is the chipselect() callback, which just does conditional GPIO. This is handled fine by the SPI core's spi_set_cs(), hence switch the driver to use the core message handling through our own transfer_one() method. As the (optional) GPIO CS is no longer deasserted at spi_master.setup() time (through spi_bitbang_setup() and the spi_bitbang.chipselect() callback), we now have to take care of that ourselves. Remove the call to spi_master_put() in sh_msiof_spi_remove(), as our SPI master is now registered using devm_spi_register_master() (spi_bitbang_start() uses the non-managed version).

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch add basic support for the quad spi controller. QSPI is a kind of spi module that allows single, dual and quad read access to external spi devices. The module has a memory mapped interface which provide direct interface for accessing data form external spi devices. The patch will configure controller clocks, device control register and for defining low level transfer apis which will be used by the spi framework to transfer data to the slave spi device(flash in this case). Test details: ------------- Tested this on dra7 board. Test1: Ran mtd_stesstest for 40000 iterations. - All iterations went through without failure. Test2: Use mtd utilities: - flash_erase to erase the flash device - mtd_debug read to read data back. - mtd_debug write to write to the data flash. diff between the write and read data shows zero.
