Re: [PATCH 0/3] add mie driver for exynos

From: "R. Chandrasekar" <rcsekar@xxxxxxxxxxx>

this patch set adds the driver support for the dithering functionality of the
mobile image enhancement (mie) module.

device tree support is added for mie.

fimd adds the mie module as plugin and calls the dithering function. dithere is
required when the panels bpp is less then fimd output.

though mie mie has other functionalities, current system uses only dithereing.

Please, move mie module into drivers/video/exynos. The mie is a interface between fimd and lcd panel(or mipi-dsi, eDP) to enhance image to be displayed. And it seems like that this doesn't need drm framework-relevant interfaces, such as gem.

And also, please refer to the below link, Common Display Framework, for more generic way.
