Hello,

Is correct dtb file used in the case?

"In standard DTB file, the LDO bypass is enabled. Therefore, to use LDO
device trees on configurations with CPU@1.2GHz, which does not support
LDO bypass mode, it is important to enable LDO. The LDO is enabled in the
following DTB files:
• imx6q-sabresd-ldo.dtb
• imx6qp-sabresd-ldo.dtb"

Regards,
Yuri.
