[RFC PATCH v1 4/4] powerpc: apm82181: integrate bluestone.dts

Christian Lamparter chunkeey at gmail.com
Thu Aug 13 08:41:53 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 alone.
