a56f489502 spi: Updates for v4.7
Another quiet release for SPI, almost entirely driver specific changes
 with the diffstat dominated by two new drivers which are about two
 thirds of it in terms of lines of code:
 
  - New drivers for PIC32 standard and SQI controllers.
  - The Cadence driver has had runtime PM support added and quite a few
    fixes and cleanups.
  - The flash-specific accelerated path support now has a feature query
    interface.
  - The pxa2xx driver has been moved to use the core DMA mapping support.

c145344763 spi: spi-fsl-dspi: Update DT binding documentation
DSPI driver support the register on the controller with big endian
mode R/W. But not use the regmap API.
So update the binding documentation for "big-endian".

1acbdeb92c spi/fsl-dspi: Convert to use regmap and add big-endian support
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.
