Hi Simon, Magnus,
The following patch series completes r8a7790 SoC and Lager board
integration for the Renesas Quad Serial Peripheral Interface. It brings
r8a7790/Lager to the same support level as r8a7791/Koelsch, allowing access
to the Spansion s25fl512s SPI FLASH for both legacy and multi-platform
kernels.
[1/7] pinctrl: sh-pfc: r8a7790: Add QSPI pin groups
[2/7] ARM: shmobile: lager legacy: Add QSPI pinmux
[3/7] ARM: shmobile: r8a7790 dtsi: Add QSPI node
[4/7] ARM: shmobile: lager dts: Add QSPI nodes
[5/7] ARM: shmobile: lager defconfig: Enable RSPI and MTD_M25P80
[6/7] ARM: shmobile: lager legacy: Enable Quad SPI transfers for the SPI
FLASH
[7/7] ARM: shmobile: lager dts: Enable Quad SPI transfers for the SPI
FLASH
Please do _not_ apply patches [6/7] and [7/7] yet, as these have a runtime
dependency on Quad SPI support in the RSPI/QSPI driver, which is queued up
in the linux-spi tree for v3.15.
Thanks!
Gr{oetje,eeting}s,
Geert

I believe qspi comes after msiof3 :-)
Apart from that the patch looks good.

Thanks a lot for this! All patches included in this series look great to me.
I noticed that 1/7 turned into a v2, so feel free to omit or include
the below ack.

That makes sense, thanks for pointing that out. You still have my Ack
though, so please include that when you resend.
Simon, can you please pick up 2-5?
