Looks like arch/arm/boot/dts/tegra114-dalmore.dts has entries like
this instead for the PMIC:
ldo9-in-supply = <&palmas_smps9_reg>:
...
Doing simlar changes for omap5-board-common.dtsi seems to fix the
issues for me:
LDO3: supplied by vdds_1v8_main
LDO4: supplied by vdds_1v8_main
ldo4: Bringing 0uV into 1800000-1800000uV
LDO5: supplied by vsys_cobra
LDO6: supplied by vdds_1v8_main
LDO7: supplied by vsys_cobra
ldo7: Bringing 0uV into 2000000-2000000uV
LDO8: supplied by vsys_cobra
LDO9: supplied by vmmcsd_fixed
See also the patch below too, and please check I got things right
based on your earlier patch :)
Now I'm wondering if the x15 related vin-supply changes are actually all
ignored? It seems that "vin" is only automatically configured for the
fixed-regulator? Maybe regulator-palmas should be updated to use the
"vin-supply" if configured to avoid confusion?

Tony
