Subject: [PATCH v3 06/11] ARM: dts: STi: Add fake reg property for remote processors
From: Patrice Chotard <patrice.chotard@...com>
As st231-gp0, st231-delta are part of SoC, we add a fake reg
property instead of moving all these nodes outside soc node.
This allows to fix the following warning when compiling
dtb with W=1 option:
arch/arm/boot/dts/stih407-b2120.dtb: Warning (simple_bus_reg):
Node /soc/st231-gp0 missing or empty reg/ranges property

v3: _ none
v2: _ add a fake reg property to node without reg property
