Subject: [PATCH 2/2] dt-bindings: interrupt-controller: convert marvell,mpic binding to YAML
Date: Fri, 21 Jun 2024 10:23:13 +0200	[thread overview]
Message-ID: <20240621082313.6605-1-kabel@kernel.org> (raw)
In-Reply-To: <20240621080719.20380-1-kabel@kernel.org>

Convert the marvell,mpic device-tree binding to YAML. Add myself as
maintainer.

-Marvell Armada 370, 375, 38x, XP Interrupt Controller
------------------------------------------------------
-
-Required properties:
-- compatible: Should be "marvell,mpic"
-- interrupt-controller: Identifies the node as an interrupt controller.
-- msi-controller: Identifies the node as an PCI Message Signaled
-  Interrupt controller.
-- #interrupt-cells: The number of cells to define the interrupts. Should be 1.
-  The cell is the IRQ number
-
-- reg: Should contain PMIC registers location and length. First pair
-  for the main interrupt registers, second pair for the per-CPU
-  interrupt registers. For this last pair, to be compliant with SMP
-  support, the "virtual" must be use (For the record, these registers
-  automatically map to the interrupt controller registers of the
-  current CPU)
-
-Optional properties:
-
-- interrupts: If defined, then it indicates that this MPIC is
-  connected as a slave to another interrupt controller. This is
-  typically the case on Armada 375 and Armada 38x, where the MPIC is
-  connected as a slave to the Cortex-A9 GIC. The provided interrupt
-  indicate to which GIC interrupt the MPIC output is connected.
-
-Example:
-
-        mpic: interrupt-controller@d0020000 {
-              compatible = "marvell,mpic";
-              #interrupt-cells = <1>;
-              #address-cells = <1>;
-              #size-cells = <1>;
-              interrupt-controller;
-              msi-controller;
-              reg = <0xd0020a00 0x1d0>,
-                    <0xd0021070 0x58>;
-        };

+description: |
+  The top-level interrupt controller on Marvell Armada 370 and XP. On these
+  platforms it also provides inter-processor interrupts.
+
+  On Marvell Armada 375, 38x and 39x this controller is wired under ARM GIC.
+
+  Provides MSI handling for the PCIe controllers.
