The driver supports the three base compatible strings, for V3, V4 and V6 of the IP core. > > + - fsl,imx6sx-lcdif > > + - items: > > + - enum: > > + - fsl,imx6sl-lcdif > > + - fsl,imx6sll-lcdif > > + - fsl,imx6ul-lcdif > > + - fsl,imx7d-lcdif > > + - fsl,imx8mq-lcdif > > + - const: fsl,imx6sx-lcdif > > > > reg: > > maxItems: 1 -- Regards, Laurent Pinchart _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
