[U-Boot] [PATCH 00/10] spi: Add Allwinner A31 SPI driver

[Jagan Teki]

This series add support for Allwinner A31 SPI controller driver.

Compared to previous version[1] separate driver for A31, this patchset 
is trying to tune the existing sun4i_spi code by adding register set, 
register bits to support both A10, A31 SPI controllers.

Any inputs?
Jagan.

Jagan Teki (10):
  spi: sun4i: Poll for rxfifo empty
  clk: sunxi: Implement SPI clocks, resets
  spi: sun4i: Simplify reg writes using set/clrbits_le32
  spi: sun4i: Access registers and bits via enum offsets
  spi: sun4i: Support fifo_depth via drvdata
  spi: sun4i: Add CLK support
  spi: sun4: Add A31 spi controller support
  spi: sun4i: Driver cleanup
  spi: kconfig: Enable SUN4I_SPI by default if ARCH_SUNXI
  board: sopine: Enable SPI/SPI-FLASH
