regmap should handle any byte ordering issues required, it is looking for a byte stream from the bus, so don't set 16 bits per word. This is likely to have tested out OK due to use of an unmerged SPI controller driver. Signed-off-by: Mark Brown <broonie@linaro.org> Tested-by: Max Filippov <jcmvbkbc@gmail.com>
