The polarity and use of these pins are very\nplatform specific, so this patch introduces the flags\nSM501FB_FLAG_PANEL_USE_VBIASEN and SM501FB_FLAG_PANEL_USE_FPEN which enable\nthe use of these pins.\n\nThis patch is needed to support the a Sharp LQ104V1DG21 lcd panel on SuperH\nplatforms such as R2D-1 and R2D-PLUS boards. Letting the sm501fb driver\ncontrol the FPEN and VBIASEN pins like today just results in lcd panel\nflicker.\n\nSigned-off-by: Magnus Damm \u003cdamm@igel.co.jp\u003e\nCc: \"Antonino A.
