Currently the example doesn't describe TCRx at all. The one upstream device tree with an mpic timer node (p1022ds) uses one large reg region to describe both, even though there are other unrelated registers in between. That device tree also contains a bogus interrupt specifier, and there's no upstream software that uses this yet, so changing this shouldn't be a problem. Add a full binding for the MPIC timer node, not just an example of 4-cell interrupts in the MPIC binding. Add fsl,available-ranges, similar to msi-available-ranges.

The networking settings are taken from mpc85xx_smp_defconfig, minus the drivers for ethernet devices not found on any current e5500 chip. The other changes are the result of running "make savedefconfig".

PCI devices are obligated to use #INTx for interrupts under legacy mode. Each PCI slot or device is typically wired to different inputs on the interrupt controller. So, Define interrupt-map and interrupt-map-mask properties for device tree to of map each PCI interrupt signal to the inputs of the interrupt controller.

The first cell is the + chipselect number, and the remaining cells are the + offset into the chipselect. +- #size-cells : Either one or two, depending on how large each chipselect + can be. +- reg : Offset and length of the register set for the device +- interrupts : IFC has two interrupts. The first one is the "common" + interrupt(CM_EVTER_STAT), and second is the NAND interrupt + (NAND_EVTER_STAT). + +- ranges : Each range corresponds to a single chipselect, and covers + the entire access window as configured. + +Child device nodes describe the devices connected to IFC such as NOR (e.g. +cfi-flash) and NAND (fsl,ifc-nand). There might be board specific devices +like FPGAs, CPLDs, etc. + +Example: + + ifc@ffe1e000 { + compatible = "fsl,ifc", "simple-bus"; + #address-cells = <2>; + #size-cells = <1>; + reg = <0x0 0xffe1e000 0 0x2000>; + interrupts = <16 2 19 2>; + + /* NOR, NAND Flashes and CPLD on board */ + ranges = <0x0 0x0 0x0 0xee000000 0x02000000 + 0x1 0x0 0x0 0xffa00000 0x00010000 + 0x3 0x0 0x0 0xffb00000 0x00020000>; + + flash@0,0 { + #address-cells = <1>; + #size-cells = <1>; + compatible = "cfi-flash"; + reg = <0x0 0x0 0x2000000>; + bank-width = <2>; + device-width = <1>; + + partition@0 { + /* 32MB for user data */ + reg = <0x0 0x02000000>; + label = "NOR Data"; + }; + }; + + flash@1,0 { + #address-cells = <1>; + #size-cells = <1>; + compatible = "fsl,ifc-nand"; + reg = <0x1 0x0 0x10000>; + + partition@0 { + /* This location must not be altered */ + /* 1MB for u-boot Bootloader Image */ + reg = <0x0 0x00100000>; + label = "NAND U-Boot Image"; + read-only; + }; + }; + + cpld@3,0 { + #address-cells = <1>; + #size-cells = <1>; + compatible = "fsl,p1010rdb-cpld"; + reg = <0x3 0x0 0x000001f>; + }; + }; -- cgit v1.2.3-70-g09d2
