RE: [PATCH v2 4/6] arm: dts: add support for Laird WB50N cpu module and DVK

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

 



Hi Alexandre,

As you are planning a clock binding rework and this patch in the series
needs a change to account for that, do you want me to re-submit after
your series or are we good to go as is?

Thanks,
Ben
