From: Thierry Reding <redacted> The P2771 has three keys (power, volume up and volume down) that are connected to pins on the AON GPIO controller.

Actually, I do see this as "VOL Down". So ignore that and I assume we re-use recovery so ... Acked-by: Jon Hunter <jonathanh@nvidia.com> Cheers Jon -- nvpublic
