Hi, This patch series aims to add ITE IT6263 LVDS to HDMI converter on i.MX8MP EVK. Combined with LVDS receiver and HDMI 1.4a transmitter, the IT6263 supports LVDS input and HDMI 1.4 output by conversion function. IT6263 product link can be found at [1]. Patch 1&2 are preparation patches to allow display modes of two existing panels to pass the added mode validation logic in patch 4. Patch 3 allows i.MX8MP LVDS Display Bridge(LDB) bridge driver to find the next non-panel bridge, that is the IT6263 in this case. Patch 4 adds mode validation logic to i.MX8MP LDB bridge driver against "ldb" clock so that it can filter out unsupported display modes read from EDID. Patch 5 adds DT binding for IT6263. Patch 6 adds IT6263 bridge driver. Only video output is supported. Patch 7 adds DT overlays to support NXP adapter cards[2][3] with IT6263 populated. Patch 8 enables the IT6263 bridge driver in defconfig.
