[U-Boot] [PATCH v2 0/8] spi: Add Allwinner A31 SPI driver

[Jagan Teki]

This series add support for Allwinner A31 SPI controller driver.

Fixed and improved conde when compared to previous series[1]

Changes for v2:
- use fifo_sta instead ctl reg in readl_poll
- use ">=" instead of negotiation in readl_poll condition
- use SPI_REG, SPI_BIT, SPI_CS macro for code improvement
- use compatible check for A31 register enablement
- add allwinner,sun6i-a31-spi compatible
- exclude driver enable patches, since it has SPI kconfig dependencies.
