Paolo Sabatino 562d96128b consolidate rk322x and rockchip 32 bit families
* merge patches from rockchip and rk322x families for current and edge
   kernels
 * adjust patches for tinkerboard to remove some cruft and overclocking
 * rework kernel configs
 * fix rk322x dmc to avoid lockup on rk3288
 * migrate rockchip-6.6 into patch series, rename all patches with
   more understandable names
 * add gen-series.sh script in tools directory (it is a naive tool to
   create patch series when you don't want to rebase everything)

Subject: [PATCH] ARM: DTS: rk3288-tinker: 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.
