[PATCH v3 4/9] ARM: DRA7: board-generic: Add basic DT support
From: Rajendra Nayak <hidden>
Date: 2013-08-04 16:27:32
Also in:
linux-omap
Subsystem:
arm port, omap2+ support, open firmware and flattened device tree bindings, the rest · Maintainers:
Russell King, Aaro Koskinen, Andreas Kemnade, Kevin Hilman, Roger Quadros, Tony Lindgren, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
From: R Sricharan <redacted> Describe minimal DT boot machine details for DRA7xx based SoC's. DRA7xx family is based on dual core ARM CORTEX A15 using GIC as the interrupt controller. The PRCM and timer infrastructure is reused from OMAP5 and so are the io descriptor tables.
