Hi Heiko,
vcc1v8_s3 is actually also a emmc supply, so I'd like to keep it around
for completenes sake.
Emmc module is supplied by PMIC vcc3v3_s3 (SWITCH_REG1) and vcc_1v8
(DCD_REG4).
So I believe removing vcc1v8_s3 has no impact on emmc supply line.
looking at the rockpro64 schematics page 10, I see vcca1v8_s3 linked
to the emmc_vdd_1v8 input and obviously also as reference for the saradc.
You are referring Pilot production release (rockpro64_v20-SCH.pdf),
please refer Second batch production release (rockpro64_v21-SCH.pdf).
both the schematic release is available at
http://wiki.pine64.org/index.php/ROCKPro64_Main_Page
So I think we really could keep it around, so that the power-tree resembles
the schematics more.
Thanks,
Akash
