[PATCH v1 0/2] spi: Introduce and use spi_bpw_to_bytes()

[Andy Shevchenko]

Recently in the discussion with David the idea of having
a common helper popped up. The helper converts the given
bits per word to bytes. The result will always be power-of-two
(e.g. for 37 bits it returns 8 bytes) or 0 for 0 input.

This mini-series introduces it and replaces current users
under drivers/spi and we expect more (and possibly some lurking
in other subsystems).

Mark, if you okay with the idea, please, make this to be an immutable
branch or tag for others to pull.

  spi: Add spi_bpw_to_bytes() helper and use it
  spi: dw: Use spi_bpw_to_bytes() helper
