Ive tried for a while now to figure out how HDMI is supposed to be disabled on the latest kernels 4.10 and up, since earlier you used either
$this->bbcode_second_pass_code('', 'bone_capemgr.disable_partno=BB-BONELT-HDMI')
or
$this->bbcode_second_pass_code('', 'fdtfile=am335x-boneblack-emmc-overlay.dtb')
Depending on the version of the kernel, but from 4.10 and forward those methods no longer work.
The file am335x-boneblack-emmc-overlay.dtb is simply not shipped with any of the new kernel packages.
Atm ive gone back to a 4.9 kernel and use the fdtfile method, which is fine. But i would like to be able to run the latest kernel.
Any insights as to if the method has changed yet again?
