Re: [PATCH v3 5/5] ARM: dts: am335x-boneblack: Add HDMI audio support

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

 



This patch is invalid now that Mike Turquette took the generic clk-gpio-gate in. The other patches in the series are still Ok.

I'll mail a new dts patch shortly.

Best regards,
Jyri
