Left-right split is enabled only by sending 0x1000 to MIPI_DCS_SET_COLUMN_ADDRESS (0x2a) and does not require any other manipulations. sharp_setup_symmetrical_split function is left as a reference for possible even-odd split implementation or video mode support where commands have to be sent to both links.
