[PATCH 0/2] spi: sh-msiof: add rcar compatibility strings

From: Yoshihiro Kaneko <hidden>
Date: 2015-12-24 11:16:45

This series adds generic rcar and SoC-specific r8a7795 compatibility
strings to the sh-msiof driver. The intention is to provide a complete
set of compatibility strings for known R-Car Gen2 and Gen3 SoCs.

This series is based on the for-next branch of Mark Brown's spi tree.

Hiromitsu Yamasaki (1):
  spi: sh-msiof: Add compatible string for r8a7795

Yoshihiro Kaneko (1):
  spi: sh-msiof: Add rcar fallback compatibility string

[PATCH 1/2] spi: sh-msiof: Add rcar fallback compatibility string

From: Yoshihiro Kaneko <hidden>
Date: 2015-12-24 11:16:46

Add fallback compatibility string for R-Car Gen2 and Gen3.
This is in keeping with the fallback scheme being adopted wherever
appropriate for drivers for Renesas SoCs.
In Addition, this patch deletes the compat strings for old SoCs.

[PATCH 2/2] spi: sh-msiof: Add compatible string for r8a7795

From: Yoshihiro Kaneko <hidden>
Date: 2015-12-24 11:16:47

From: Hiromitsu Yamasaki <redacted>

Simply documents new compatibility string.
As a previous patch adds a generic R-Car Gen3 compatibility string
there appears to be no need for a driver updates.
