Subject: [PATCH 23/28] ARM: DTS: rk3288-tinker.dts: Defining the SPI interface
Taken from, and tested by @TonyMac32 .
Well, the original one was tested by him but I had to adapt the
registers definitions to the new 64-bits LPAE-compliant syntax.
Therefore that *might* break, along with a few other patches.
