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.

||
