Cover letter [RFC/PATCH 0/2] spi: spi-dw: Select 16b or 32b register access
From: Thor Thayer <[email protected]>
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.

spi: dw-spi: Pointers select 16b vs. 32b DesignWare access
