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.
