Hi Neil,
[Ship]
Sorry for not following on my query on not able to boot from microSD
card on Odroid N2.
I have been trying various changes in *meson-g12b-odroid-n2.dts* most
of them related
to linking the power to tflash_vdd and tf_io nodes.
From the schematics it seems
tflash_vdd (TFLASH_VDD_EN) vin-supply = <&vddao_3v3>;
tf_io (TF_3V3N_1V8_EN) vin-supply = <&vcc_5v>;
but it seen some thing core is missing in Initialization of tf_io.
Below regulator_summary confirm my finding ft_io not linked to any
main regulator.
[root@alarm ~]# cat /sys/kernel/debug/regulator/regulator_summary
regulator use open bypass opmode voltage
current min max

Also I could not figure out how Hardkernel (Amlogic) source code
initialize the power for regulator.
If you could share some input I will then try to debug this future.
Best Regards
-Anand
