[PATCH 08/17] ARM: dts: Add missing hsi node for omap4

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On omap4 we're missing the hsi node with it's related "ti,hwmods"
property that the SoC interconnect code needs.

Note that this will only show up as a bug with "doesn't have
mpu register target base" boot errors when the legacy platform
data is removed.

Let's also update the binding accrodingly while at it.
