[PATCH 10/11] ARM: dts: msm: Add nodes necessary for SMP boot

Stephen Boyd sboyd at codeaurora.org
Fri Nov 1 18:08:58 EDT 2013


From: Rohit Vaswani <rvaswani at codeaurora.org>

Add the necessary nodes to support SMP on MSM8960 and
MSM8974/APQ8074. While we're here also add in the error
interrupts for the krait cache error detection.
