2018-07-25dt-bindings: remove 'interrupt-parent' from bindingsRob Herring1-3/+0
'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

2017-10-11irqchip/ls-scfg-msi: Add LS1012a MSI supportHou Zhiqiang1-0/+1
The ls1012a implements only 1 MSI controller, and it is the same as ls1043a.

2017-08-31irqchip/ls-scfg-msi: Add LS1043a v1.1 MSI supportMinghuan Lian1-0/+1
A MSI controller of LS1043a v1.0 only includes one MSIR and is assigned one GIC interrupt. In order to support affinity, LS1043a v1.1 MSI is assigned 4 MSIRs and 4 GIC interrupts. But the MSIR has the different offset and only supports 8 MSIs. The bits between variable bit_start and bit_end in structure ls_scfg_msir are used to show 8 MSI interrupts. msir_irqs and msir_base are added to describe the difference of MSI between LS1043a v1.1 and other SoCs.

2017-08-31irqchip/ls-scfg-msi: Fix typo of MSI compatible stringsMinghuan Lian1-3/+3
The patch is to fix typo of the Layerscape SCFG MSI dts compatible strings. "1" is replaced by "l". Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Minghuan Lian <Minghuan.Lian@nxp.com> Signed-off-by: Hou Zhiqiang <Zhiqiang.Hou@nxp.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2016-05-04dt/bindings: Add bindings for Layerscape SCFG MSIMinghuan Lian1-0/+30
Some Layerscape SoCs use a simple MSI controller implementation. It contains only two SCFG register to trigger and describe a group 32 MSI interrupts. The patch adds bindings to describe the controller. Signed-off-by: Minghuan Lian <Minghuan.Lian@nxp.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
