2016-04-14ARM: dts: kirkwood: Fixup pcie DT warningsAndrew Lunn1-10/+8
PCIe has a range property, so the unit name should contain an address. Make use of the label to enable individual PCIe busses. Also, fixup the synology dtsi file which added a label pcie2 rather than using the existing pcie1 label.

2013-10-01ARM: kirkwood: Remove kirkwood_setup_wins and rely on the DT bindingJason Gunthorpe1-1/+0
kirkwood_setup_wins is the last manual caller of mbus in kirkwood, don't call it for DT boards and rely on the DT having a mbus node with a proper ranges property to setup these windows. Move all the mbus ranges properties for all boards into kirkwood.dtsi, since they are currently all the same. This makes the DT self consistent, since the physical address of the NAND and CRYPTO are both referenced internally. The arbitary Linux constants KIRKWOOD_NAND_MEM_PHYS_BASE and KIRKWOOD_SRAM_PHYS_BASE no longer have to match the DT values.

2013-08-06ARM: kirkwood: Relocate PCIe device tree nodesEzequiel Garcia1-8/+11
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.

2013-05-27ARM: kirkwood: refactor dtsi to largest common nodesValentin Longchamp1-0/+1
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.

2013-05-27arm: kirkwood: convert ZyXEL NSA310 to use DT for the PCIe interfaceThomas Petazzoni1-0/+8
Now that the PCIe mvebu driver is usable on Kirkwood, use it instead of the legacy PCIe code, since it allows to describe the PCIe interfaces in the Device Tree. Since it was the only device left that prevented this platform to use the Device Tree only, we remove the board-nsa310.c file and the related Kconfig/Makefile bits.

2013-05-27arm: kirkwood: nsa310: move pinmux configs to the right devicesThomas Petazzoni1-16/+13
When the pinmux mechanism was added in Kirkwood, the device driver core was not yet providing the possibility of attaching pinmux configurations to all devices, drivers had to do it explicitly, and not all drivers were doing this. Now that the driver core does that in a generic way, it makes sense to attach the pinmux configuration to their corresponding devices. This allows the pinctrl subsystem to show in debugfs to which device is related which pins, for example: pin 41 (PIN41): gpio-leds.1 mvebu-gpio:41 function gpio group mpp41 pin 42 (PIN42): gpio-leds.1 mvebu-gpio:42 function gpio group mpp42 pin 43 (PIN43): gpio-leds.1 mvebu-gpio:43 function gpio group mpp43 Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Acked-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Jason Cooper <jason@lakedaemon.net>
2013-03-08ARM: kirkwood: of_serial: fix clock gating by removing clock-frequencyJason Cooper1-1/+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 adt7476 device itself is not at reach of device tree, AFAIK and requires more work at there? Thanks for your valuable comments. Following is a new patch that should address the problems and mistakes you pointed and also some of the pointed by Jason Cooper. The nand and i2c are now defined at DT and I also removed the pointless defines and ARM_APPENDED_DTB. It is based against the Linus' official 3.6 version.
