Define the Porter board dependent part of the QSPI device node. Add device nodes for Spansion S25FL512S SPI flash and the MTD partitions on it. This patch is mostly analogous to the commit f59838d44835 ("ARM: shmobile: henninger: add QSPI DT support") as there are no differences between the boards in this respect. Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> --- This patch is against 'renesas-devel-20151008-v4.3-rc4' tag of Simon Horman's 'renesas.git' repo plus the Porter I2C2 and VIN0/ADV7180 patches posted earlier. Changes in version 2: - fixed the commit citing style and reformatted that whole paragraph. arch/arm/boot/dts/r8a7791-porter.dts | 38 +++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) -- To unsubscribe from this list: send the line "unsubscribe linux-sh" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
