Re: [PATCH v2] mfd: arizona: Move useful defines into a dt-binding include

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

 




Why are you using this address for MFD?

> Move parts of linux/mfd/arizona/pdata.h and gpio.h into a new file in
> the dt-binding directory for use by device tree bindings. This also
> makes gpio.h redundant so remove it in the process.

> Changes since v1:
>  - Removed some defines that will never be used in DT from the

>  - Added some convience defines for the most common pin configs
>    (input/output/default)
>  - Updated the binding documentation to use the new defines to
>    give some context to their usage
