HDMI No signal for koelsch Board

[Jithin T Raj <jithin.t@xxxxxxxxxxxxxxx>]

hi,
    I have a trouble in getting HDMI OUT in koelsche Board  



I am using source tree v4.1.17-ltsi..also i have applied the below patch to shmobile_defconfig

diff --git a/arch/arm/configs/shmobile_defconfig b/arch/arm/configs/shmobile_defconfig
index 0bdeb4925be4..3aef019c0de7 100644

 # CONFIG_LCD_CLASS_DEVICE is not set

and when I checked the pinmux it is like

du_pins: du {
        renesas,groups = "du_rgb666", "du_sync", "du_disp", "du_clk_out_0";
        renesas,function = "du";
    };

do I need to change it to   24 bit (du_rgb888)? my UBoot is gb653737..
