Hi Maxime, As I already mailed you about yesterday as a headsup here is a fix for the simplefb dt nodes introduced for sunxi in 3.19, I would like to get this into 3.19 to avoid the need for carrying compatibility code for the old nodes in u-boot (as 3.19 is going to be the first kernel release with sunxi simplefb support). >From the commit message of the attached patch: ### Testing has shown that on sun4i the display backend engine does not have deep enough fifo-s causing flickering / tearing in full-hd mode due to fifo underruns. This can be avoided by letting the display frontend engine do the dma from memory, and then letting it feed the data directly into the backend unmodified, as the frontend does have deep enough fifo-s. Note since u-boot-v2015.01 has been released using the de_be0-lcd0-hdmi pipeline on sun4i, we need to keep that one around too (unfortunately). ### I've send a patch to the u-boot mailinglist this morning to make u-boot v2015.04 (and later) use a de_fe0-de_be0-lcd0-hdmi pipeline on sun4i thus fixing the tearing / flickering. Can you please queue this patch up as a fix for 3.19 ?
