[meta-freescale] DORA and LDO Bypass

[Haedt, Jason]

Hello Yocto Friends,


I am using u-boot-fslc (FSL's U-boot port) so if that's the key, then I'm not sure what I'm doing wrong.  Has anyone else used the LDO Bypass with the GPU/VPU enabled?

I'm wondering if it is possible to put the i.MX6Q’s internal LDO requlators into bypass and still use the GPU?

Yes, you need to use FSL U-boot, which supports LDO bypass mode.
U-boot mainline does not support LDO bypass, so we need to use the imx6q-sabresd-ldo.dtb variant.
