This change documents a new property for the snps,dw-apb-ssi device, allowing an implementer to specify either four byte or two bytes access to the SPI controller data register. This supports a change that unbreaks this driver on picoXcell platforms. Signed-off-by: Michael van der Westhuizen <michael@smart-africa.com> --- Changes in v3: - Rename the DT property as requested by Rob Herring. Changes in v2: - Incorporate review feedback from Andy Shevchenko, reworking the bindings to reflect common practice.
