This is basically a design that has been introduced in the A31 (sun6i family). I guess we should just call the driver and Kconfig symbols sun6i_csi (even though we don't support it yet). It also used on the A23, A33, A80, A83T, H3, and probably the H5 and A64. Maxime -- Maxime Ripard, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com --jeum2g7ncqcdbp47--
