Subject: Using DSI PLL for LCD pixel clock
Date: Mon, 23 May 2011 10:26:02 +0300	[thread overview]
Message-ID: <1306135562.1871.3.camel@deskari> (raw)

Hi Steve,

I know you've been using OMAP2_DSS_USE_DSI_PLL Kconfig option to use DSI
PLL for pixel clock, so I wanted to point out that that has changed in
the current DSS2 master (soon to be merged, I hope). You will now need
to select the clock usage in the board file, for example:

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

        .driver_name            = "generic_dpi_panel",
        .data                   = &lcd43_panel,
        .phy.dpi.data_lines     = 24,

+               },
+       },
 };
