From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: "Miouyouyou (Myy)" Date: Mon, 5 Nov 2018 22:15:14 +0100 Subject: 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.
