Subject: Re: [PATCH] arm64: dts: exynosautov9: convert serial_0 for USI

According to USI v2 driver change[1], serial_0 node should be
converted to use the USI node hierarchy. syscon_peric0 will be used as
a syscon node to control the USI00_USI_SW_CONF register.
This also changes the serial node name from uart@ to serial@.

Put this one alphabetically in DTS.

Regarding usi / serial/hsi2c/spi nodes, I thought it looks better to keep the order of DTSi.
Anyway, I'll follow alphabetical order in DTS. I'll apply this next patch.

Best Regards,
