[PATCH v2 15/21] dt-bindings: i2c: document support for SA8255p

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

 



Add compatible representing i2c support on SA8255p.

Clocks and interconnects are being configured in Firmware VM
on SA8255p, therefore making them optional.
