Subject: BeagleBone Black - linux-ti-staging and kernel modesetting

Hi,
I am using Yocto dora release with latest meta-ti git compiling for
BeagleBone Black using systemd.
For systemd to boot I had created linux-ti-staging_3.12.bbappend with
do_configure_append() that
appends the following options to kernel config:
CONFIG_CGROUPS=y
CONFIG_FHANDLE=y
More kernel options to enable additional support for systemd can be
found at: http://cgit.freedesktop.org/systemd/systemd/tree/README
I have also added the following for graphics support:
CONFIG_DRM=y
CONFIG_DRM_KMS_HELPER=y
CONFIG_DRM_GEM_CMA_HELPER=y
CONFIG_DRM_KMS_CMA_HELPER=y
CONFIG_DRM_I2C_NXP_TDA998X=y
CONFIG_DRM_TILCDC=y
The kernel mode switching (using xf86-video-modesetting) with HDMI
output however is not working.
The kernel log shows:
tilcdc 4830e000.lcdc: no encoders/connectors found
tilcdc 4830e000.lcdc: failed to initialize mode setting
The expected result (from Arch Linux ARM) is:
tilcdc 4830e000.fb: found TDA19988
tilcdc 4830e000.fb: fb0: frame buffer device
tilcdc 4830e000.fb: registered panic notifier
[drm] Initialized tilcdc 1.0.0 20121205 on minor 0
/sys/class/drm/card0/card0-HDMI-A-1 doesn't exist also.
What am I missing to get KMS working with meta-ti linux-ti-staging for
the BeagleBone Black?
Regards,
Jonathan
