Re: [PATCH 3/6] arm64: renesas: r8a77995: add I2C support

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

 



Hi Ulrich, Wolfram,

Is there any update to this patch series?
This seems to be the latest I could find for D3.

I need I2C on D3 for my current additional task, so I'll try to use these
patches as the base for now.

(Patch 3, 4, 5 apply on top of renesas-drivers-2018-01-09-v4.15-rc7, so if it
works - that's enough for me for the moment)

Please let me know if there is a newer series or branch that I should be
considering as a base.
