[RFC/PATCH 0/2] spi: spi-dw: Select 16b or 32b register access

[<tthayer@xxxxxxxxxxxxxxxxxxxxx>]

From: Thor Thayer <tthayer@xxxxxxxxxxxxxxxxxxxxx>

The Altera Arria10 SoC requires 32 bit accesses to peripherals. The
DesignWare SPI peripheral registers are on 32bit boundaries so this
patch is minimal. Function pointers are used to select 32bit access
or 16bit accesses.

Thor Thayer (2):
  dt-binding: spi: spi-dw: Select 16b or 32b access for Designware SPI
  spi: dw-spi: Pointers select 16b vs. 32b DesignWare access
