2014-05-05ARM: dts: kirkwood: set default pinctrl for SPI0Sebastian Hesselbarth1-0/+6
Most Kirkwood boards use the default SPI0 pinctrl setting anyway. Add a default pinctrl setting to the toplevel SoC SPI0 node and put a note in front of the corresponding pinctrl node to overwrite the setting on board level. Currently, only T5325 is using a different setting and already overwrites the corresponding pinctrl node.

2014-03-04ARM: kirkwood: Add i2c alias so setting bus numberAndrew Lunn1-1/+2
When using platform_driver instantiation, the i2c bus was given bus number 0. The kirkwood-t5325 audio driver has this bus number hard coded for the address of the codec. However by default device tree i2c busses are dynamically allocated a bus number, starting from 1. Thus the kirkwood-t5325 cannot find its audio codec. By adding an alias in the DT file we can control the bus number and set it to 0. The codec can then be found.

2014-01-16dt/bindings: remove device_type "network" referencesGrant Likely1-2/+0
device_type is deprecated and the kernel doesn't require it in most cases. The only exceptions for flat tree users are the "gianfar", "ucc_geth" and "ibm,emac" bindings, and arguably that requirement could be relaxed for ucc_geth and ibm,emac (that is a task for separate patches though). This patch removes references to device_type="network" from the binding documentation where possible and removes the properties from ARM and microblaze dts files. This patch does not modify the powerpc .dts files since there are a much larger number of them affected and I think the ucc_geth, ibm,emac and gianfar users should be addressed before clearing out the references to reduce the chance of breakage.

Move all the mbus ranges properties for all boards into kirkwood.dtsi, since they are currently all the same.

2013-08-06ARM: kirkwood: Relocate PCIe device tree nodesEzequiel Garcia1-1/+4
Now that mbus has been added to the device tree, it's possible to move the PCIe nodes out of the ocp node, placing it directly below the mbus. This is a more accurate representation of the hardware. Moving the PCIe nodes, we now need to introduce an extra cell to encode the window target ID and attribute. Since this depends on the PCIe port, we split the ranges translation entries, to correspond to each MBus window. In addition, we encode the PCIe memory and I/O apertures in the MBus node, according to the MBus DT binding specification. The choice made is 0xe0000000-0xf0000000 for memory space, and 0xf200000-0xf2100000 for I/O space. These apertures can be changed in each per-board DT file.

2013-06-21ARM: Kirkwood: Fix the internal register ranges translationEzequiel Garcia1-2/+3
Although the internal register window size is 1 MiB, the previous ranges translation for the internal register space had a size of 0x4000000. This was done to allow the crypto and nand node to access the corresponding 'sram' and 'nand' decoding windows. In order to describe the hardware more accurately, we declare the real 1 MiB internal register space in the ranges, and add a translation entry for the nand node to access the 'nand' window.

Some kirkwood variants (for instance present in the prestera SoCs) do not have all the peripherals whose nodes are declared in kirkwood.dtsi. These missing peripherals are SATA, SDIO, and RTC. As discussed in [1], to avoid that these missing peripherals get initialized which could result in system hangs when accessing undocumented/not present HW registers, their corresponding OF nodes should not get declared at all for some kirkwood variants. The corresponding OF nodes of these peripherals thus are moved from kirkwood.dtsi to the kirkwood-628x.dtsi files so that they still are initialized for these variants where they are present.

2013-03-09ARM: kirkwood: of_serial: fix clock gating by removing clock-frequencyJason Cooper1-2/+0
When DT support for kirkwood was first introduced, there was no clock infrastructure. As a result, we had to manually pass the clock-frequency to the driver from the device node. Unfortunately, on kirkwood, with minimal config or all module configs, clock-frequency breaks booting because of_serial doesn't consume the gate_clk when clock-frequency is defined. The end result on kirkwood is that runit gets gated, and then the boot fails when the kernel tries to write to the serial port. Fix the issue by removing the clock-frequency parameter from all kirkwood dts files. Booted on dreamplug without earlyprintk and successfully logged in via ttyS0.

The gpio controller on kirkwood can provide interrupts but is missing the #interrupt-cells property. This patch just adds it to both gpio controllers. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> Signed-off-by: Jason Cooper <jason@lakedaemon.net>

Pull ARM SoC updates for Marvell mvebu/kirkwood from Olof Johansson: "This is a branch with updates for Marvell's mvebu/kirkwood platforms. They came in late-ish, and were heavily interdependent such that it didn't make sense to split them up across the cross-platform topic branches. So here they are (for the second release in a row) in a branch on their own." * tag 'mvebu' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (88 commits) arm: l2x0: add aurora related properties to OF binding arm: mvebu: add Aurora L2 Cache Controller to the DT arm: mvebu: add L2 cache support dma: mv_xor: fix error handling path dma: mv_xor: fix error checking of irq_of_parse_and_map() dma: mv_xor: use request_irq() instead of devm_request_irq() dma: mv_xor: clear the window override control registers arm: mvebu: fix address decoding armada_cfg_base() function ARM: mvebu: update defconfig with I2C and RTC support ARM: mvebu: Add SATA support for OpenBlocks AX3-4 ARM: mvebu: Add support for the RTC in OpenBlocks AX3-4 ARM: mvebu: Add support for I2C on OpenBlocks AX3-4 ARM: mvebu: Add support for I2C controllers in Armada 370/XP arm: mvebu: Add hardware I/O Coherency support arm: plat-orion: Add coherency attribute when setup mbus target arm: dma mapping: Export a dma ops function arm_dma_set_mask arm: mvebu: Add SMP support for Armada XP arm: mm: Add support for PJ4B cpu and init routines arm: mvebu: Add IPI support via doorbells arm: mvebu: Add initial support for power managmement service unit ...
