You will now need to select the clock usage in the board file, for example: --- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html diff --git a/arch/arm/mach-omap2/board-overo.c b/arch/arm/mach-omap2/board-overo.c index 9d192ff..68a33bb 100644 --- a/arch/arm/mach-omap2/board-overo.c +++ b/arch/arm/mach-omap2/board-overo.c @@ -345,6 +345,11 @@ static struct omap_dss_device overo_lcd43_device = { .driver_name = "generic_dpi_panel", .data = &lcd43_panel, .phy.dpi.data_lines = 24, + .clocks = { + .dispc = { + .dispc_fclk_src = OMAP_DSS_CLK_SRC_DSI_PLL_HSDIV_DISPC, + }, + }, }; Tomi
