[PATCH v5 0/6]dt-bindings: Firmware node binding for ZynqMP core

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Base firmware node and clock child node binding are part of mainline kernel.
This patchset adds documentation to describe rest of the firmware child node bindings. 

Complete firmware DT node example is shown below for ease of understanding:

firmware {

                        #clock-cells = <1>;
