[PATCH 00/12] spi: rspi and sh-msiof driver updates

[Geert Uytterhoeven <geert+renesas@glider.be>]

	Hi Mark, Simon,

Here's a series of Renesas RSPI/QSPI and SH-MSIOF SPI driver updates.
I grouped them in three parts:
  - [1-5] are for the rspi driver (Mark),
  - [6-8] are for the sh-msiof driver (Mark),
  - [9-12] are for the R-Car Gen2 DTSes (Simon).

Summary of changes:
  - [1] and [6] are bug fixes I have sent before, but that weren't applied
    due to dependency confusion,
  - [2] is a new cosmetic fix,
  - [3] makes rspi use a new helper function that will be available as of
    v3.17-rc1,
  - [4-5] and [7-8] make DMA work with the new R-Car DMAC driver,
    developed by Laurent Pinchart in the series "[PATCH v2 0/8] R-Car Gen2
    DMA Controller driver"
    (http://www.spinics.net/lists/linux-sh/msg33890.html),
  - [9-12] enable DMA in DT for r8a7791 and r8a7790, and depend on
    "[PATCH v2 8/8] ARM: shmobile: r8a7791: Add DMAC devices to DT"
    (http://www.spinics.net/lists/linux-sh/msg33897.html) resp.
    "[PATCH v2 7/8] ARM: shmobile: r8a7790: Add DMAC devices to DT"
    (http://www.spinics.net/lists/linux-sh/msg33896.html) of the
    aforementioned series.

This has been tested on r8a7791/koelsch.

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