Hi,

I think some of them can be shared? If you think this is inappropriate,
I will abandon this. By the way, it seems that the OrangePi R2S lacks
publicly available schematics.

Some parts are the same:
- emmc
- eeprom
- ethernet
- p1 pmic
- combo phy
- pdma / uart0
- always-on regulator
- pcie (excluding supply)
- usb2/3 (excluding supply)

Some parts are different:
- hdmi
- qspi
- sdcard
- gpio led
- sdio wifi
- audio codec
- pcie supply
- usb2/3 supply
- gpio regulator

Thanks,
Chukun
