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. Patch 9 updates MAINTAINERS to add maintainer for IT6263 driver.
