[PATCH v3 5/5] powerpc: apm82181: integrate bluestone.dts

Sun Sep 6 08:06:15 AEST 2020
This patch tries to integrate the existing bluestone.dts into the
apm82181.dtsi framework.
The original bluestone.dts produces a peculiar warning message.
> bluestone.dts:120.10-125.4: Warning (i2c_bus_reg):
> /plb/opb/i2c at ef600700/sttm at 4C: I2C bus unit address format error, expected "4c"
For now, this has been kept as-is.
