[PATCH v2 0/3] spi: sh-msiof: Add reset of registers before starting transfer

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

	Hi Mark,

This patch series resets the MSIOF registers before starting a transfer,
to comply with the procedure documented in the Hardware Manual.

Changes compared to v1:
  - New patches 1 and 2, in response to review comments on v1
    (although sh_msiof_modify_ctr_wait() didn't turn out to be suitable
    for calling by sh_msiof_spi_reset_regs()),
  - Use BIT(),
  - Use readl_poll_timeout_atomic().

Thanks!

Geert Uytterhoeven (3):
  spi: sh-msiof: Use BIT() and GENMASK()
  spi: sh-msiof: Use readl_poll_timeout_atomic() instead of open-coding
  spi: sh-msiof: Add reset of registers before starting transfer

when I'm talking to journalists I just say "programmer" or something like that.
