Make FSL eSPI CSnBEF and CSnAFT fields in ESPI_SPMODEn registers (n=0,1,2,3) configurable through device tree. CSnBEF is the chip select setup time. It's the delay in bits from the activation of chip select pin to the first clock for data frame. CSnAFT is the chip select hold time. It's the delay in bits from the last clock for data frame to the deactivation of chip select pin. The FSL eSPI driver hardcodes CSnBEF and CSnAFT to 0. Need to set them to a different value for some device. Signed-off-by: NJane Wan <Jane.Wan@gainspeed.com> Signed-off-by: NMark Brown <broonie@linaro.org>

Add support for the MSIOF variant in the R-Car H2 (r8a7790) and M2 (r8a7791) SoCs. Binding documentation: - Add future-proof "renesas,msiof-<soctype>" compatible values, - The default for "renesas,rx-fifo-size" is 256 on R-Car H2 and M2, - "renesas,tx-fifo-size" and "renesas,rx-fifo-size" are deprecated for soctype-specific bindings, - Add example bindings. Implementation: - MSIOF on R-Car H2 and M2 requires the transmission of dummy data if data is being received only (cfr. "Set SICTR.TSCKE to 1" and "Write dummy transmission data to SITFDR" in paragraph "Transmit and Receive Procedures" of the Hardware User's Manual). - As RX depends on TX, MSIOF on R-Car H2 and M2 also lacks the RSCR register (Receive Clock Select Register), and some bits in the RMDR1 (Receive Mode Register 1) and TMDR2 (Transmit Mode Register 2) registers. - Use the recently introduced SPI_MASTER_MUST_TX flag to enable support for dummy transmission in the SPI core, and to differentiate from other MSIOF implementations in code paths that need this. - New DT compatible values ("renesas,msiof-r8a7790" and "renesas,msiof-r8a7791") are added, as well as new platform device names ("spi_r8a7790_msiof" and "spi_r8a7791_msiof"). - The default RX FIFO size is 256 words on R-Car H2 and M2. This is loosely based on a set of patches from Takashi Yoshii <takasi-y@ops.dti.ne.jp>.

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.

Freescale DSPI module will have two endianess in different platform, but ARM is little endian. So when DSPI in big endian, core in little endian, readl and writel can not adjust R/W register in this condition. This patch will remove general readl/writel, and import regmap mechanism. Data endian will be transfered in regmap APIs. Documents: dspi add bool "big-endian" in dts node if DSPI module work in big endian.

Many of the Tegra DT binding documents say nothing about the clocks or clock-names properties, yet those are present and required in DT files.

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.
