This still doesn't add any of the backlight/panel GPIO programming, which I believe is required before we enable any LCDs. We could add the HDMI node without that though. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

So let's hold on this and wait for the backlight/panel working on cardhu. > -- > To unsubscribe from this list: send the line "unsubscribe linux-tegra" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

This patch adds the RGB & HDMI nodes in Tegra 30 cardhu's dts. This makes the LVDS & HDMI working. Signed-off-by: Mark Zhang <markz@nvidia.com> --- Changes: - This patch depcrates the patch: "[PATCH V2] ARM: dt: tegra: cardhu: Add drm components" Because the issue that LCD and HDMI can't work at the same time has been fixed by Thierry's patch: "drm: tegra: Use framebuffer pitch as line stride" arch/arm/boot/dts/tegra30-cardhu.dtsi | 23 +++++++++++++++++++++-- 1 file changed, 21 insertions(+), 2 deletions(-)
