Subject: [PATCH 1/2] gspca_sonixj: add hardware vertical flip support for hama AC-150
Date: Sun, 17 Oct 2010 13:08:01 +0200 [thread overview]
Message-ID: <4CBAD911.9070800@freemail.hu> (raw)
From: Márton Németh <nm127@freemail.hu>
The PO2030N sensor chip found in hama AC-150 webcam supports vertical flipping
the image by hardware. Add support for this in the gspca_sonixj driver also.
