Hi all, This series introduce the Alpine MSIX driver, and enables it in both the Alpine v1 and Alpine v2 device trees.
This series depends on "[PATCH v2 0/3] arm64: introduce the Alpine support": https://lkml.org/lkml/2016/2/10/83 You can find the series at: https://github.com/atenart/linux.git 4.5-rc1/alpinev2-msix Antoine Since v1: - Added an interrupt-parent property in the documentation example. - Updated to use bitmap_*() instead of *_bit(). - Removed the static irq_set_affinity to use irq_chip_set_affinity_parent(). - Updated the address field to use phys_addr_t. - Added a comment on why we're setting bit 16 in the address. - Patched the gic_set_affinity() function in irqchip/gic-v3.
