Hello.
Here's the set of 3 patches against Simon Horman's 'renesas.git' repo,
'renesas-devel-20160902-v4.8-rc4' tag plus the Wheat board patches posted this
week. We're adding the R8A7792/Wheat QSPI clocks and device nodes. The board
patch depends on the PFC driver QSPI patch in order for the QSPI pins to be
configured...
[1/3] ARM: dts: r8a7792: add QSPI clock
[2/3] ARM: dts: r8a7792: add QSPI support
[3/3] ARM: dts: wheat: add QSPI support
WBR, Sergei
