I think the patches 1-5 are ready for merging. See the details below.
I applied these on top of v4.0-rc3, booted up BBB, and loaded the modules. After doing that and waiting a few secs:

[ 26.189766] [drm:drm_crtc_helper_set_config [drm_kms_helper]] *ERROR* failed to set mode on [CRTC:18]
Also running modetest spams with similar warnings.
I tried first with 3.19 and then with 4.0-rc5, checked the boot and then
the modetest, but I could not reproduce the trace above.
In my config I just have CONFIG_DRM=m and CONFIG_DRM_I2C_NXP_TDA998X=m
on top of plain omap2plus_defconfig. Should I take something else?
Anyway, I doubt this has anything to do with my patches. Could you give
it one more try without my patches?
Best regards,
Jyri
