[PATCH 09/10] ARM: mvebu: add Device Tree files for Armada 39x SoC and board
Thomas Petazzoni
thomas.petazzoni at free-electrons.com
Fri Feb 6 07:57:55 PST 2015
This commit adds the Device Tree files for the Armada 39x family of
processors, as well as one Armada 398 Development Board.
Like for other Marvell EBU families, a common armada-39x.dtsi contains
the description of the common features of all Armada 39x SoCs, while
armada-390.dtsi and armada-398.dtsi respectively describe the
specificities of those SoCs.
Finally, an armada-398-db.dts file is added to describe the Armada 398
Development Board itself.
So far, the following features are supported:
* SMP: dual Cortex-A9
* Basic ARM IPs: SCU, timer, GIC
* Basic Marvell IPs: pin-muxing, clocks, system controller, MBus
controller, MPIC interrupt controller, timer, CPU reset for SMP,
PMSU.
* I2C
* UART
* PCIe
Additional features will be supported in the future.
