Docs: dt: add generic MSI bindings

2015-08-25T16:29:57Z

Currently msi-parent is used in a couple of drivers despite being fairly underspecified. This patch adds a generic binding for MSIs (including the existing msi-parent property) enabling the description of platform devices capable of using MSIs. While MSIs are primarily distinguished by doorbell and payload, some MSI controllers (e.g. the GICv3 ITS) also use side-band information accompanying the write to identify the master which originated the MSI, to allow for sandboxing. This sideband information is non-probeable and needs to be described in the DT. Other MSI controllers may have additional configuration details which need to be described per-master. This patch adds a generic msi-parent binding document, extending the de-facto standard with a new (optional) #msi-cells which can be used to express any per-master configuration and/or sideband data. This is sufficient to describe non-hotpluggable devices. For busses where sideband data may be derived from some bus-specific master ID scheme, other properties will be required to describe the mapping.

irqchip/bcm2835: Add support for being used as a second level controller

2015-08-20T20:38:41Z

The BCM2836 (Raspberry Pi 2) uses two levels of interrupt handling with the CPU-local interrupts being the root, so we need to register ours as chained off of the CPU's local interrupt.
