Hi all,
This series introduces the support for the arm64 Alpine family from
Annapurna Labs, by adding a device tree for the Alpine v2 EVP. This
board has 4 Cortex A57 and a few nodes in its device tree for now.
You can find the series at:
https://github.com/atenart/linux.git 4.5-rc1/alpinev2-bringup
Antoine
Since v1:
- Fixed the armv8-timer interrupts.
- Added the GICV and GIVH ranges.
- Added the GIC maintainance interrupt.
- Moved the aliases to the dts file.
- Fixed the pci node.
- Added the arm,psci cpu_off and cpu_suspend functions.
- Added the io-fabric bus.
- Fixed the stdout-path.
