Hm. I was trying to compile a kernel to verify this, but it took more than
overnight to build the packages...
This is ODROID's XU4 4.2 tree config:
https://github.com/tobetter/linux/blob/39fb8734966df320584f8c186652cec831e90054/arch/arm/configs/odroidxu4_defconfig
On a guess, the relevant parts would probably be
CONFIG_EXYNOS_VIDEO=m
CONFIG_EXYNOS_MIPI_DSI=m
CONFIG_DRM_EXYNOS=m
CONFIG_DRM_EXYNOS_MIXER=y [not in that config, but _HDMI depends on it]
CONFIG_DRM_EXYNOS_FIMD=y
CONFIG_DRM_EXYNOS_DSI=y
CONFIG_DRM_EXYNOS_DP=y
CONFIG_DRM_EXYNOS_HDMI=y
CONFIG_PHY_EXYNOS_MIPI_VIDEO=m
CONFIG_PHY_EXYNOS_DP_VIDEO=m
There are also power management settings that I believe might be useful
(not related to display):
CONFIG_DEVFREQ_EVENT_EXYNOS_PPMU=y
CONFIG_ARM_EXYNOS_CPUIDLE=y
and I guess also
CONFIG_EXYNOS_ADC=m
I can try compiling a kernel with all of those set and see if I get any more
video, but if you have any tricks to make dpkg-buildpackage go faster
for kernel builds, please let me know :-)
