PINE64 Rock64 - How to get SPI driver working

[Johannes Krottmayer]

I finally resolved the issue:

=> sf probe
SF: Detected gd25q128 with page size 256 Bytes, erase size 4 KiB, total
16 MiB
=>

The flash device will be correctly detected.
The problem was missing support in the clock driver of the SoC.

Should I release a patch for it?
