Subject: [PATCH 0/2] media: v4l2-mediabus: add support for dual edge sampling

Hi all,

Some devices (such as the Rockchip Video Input Processor (VIP) or the IT6801
HDMI receiver) support sampling of the parallel data at both edges of the
interface pixel clock in order to reduce the pixel clock by two.
This series adds support for this feature by using the pclk-sample device
tree property.

Looking forward to your comments!

Best regards,
Michael
