[PATCH v3 02/11] dt-bindings: i2c: apple,i2c: Add power-domains property

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

 



This will bind to the PMGR pwrstate nodes that control power/clock
gating to SoC blocks. The i2c driver doesn't do runtime-pm yet, so
initially this will just keep the domain on permanently.
