* ARM: orion5x: add Device Bus description at SoC levelThomas Petazzoni2014-04-261-0/+40
| | | | | | | | | | | This commit adds the necessary SoC-level Device Tree definitions to describe the Device Bus of Orion5x SOCs. The Device Bus is mainly used to connect NOR flashes to the system.

* ARM: orion5x: update I2C description at SoC levelThomas Petazzoni2014-04-261-1/+1
| | | | | | | | | | | | | | | This commit fixes the Orion5x SoC definition to: * Not define a clock-frequency, as it should be described on a per-board basis. * Declare the appropriate clock reference, so that the driver can do correct divisors calculations for the I2C bus.

* ARM: orion5x: switch to DT interrupts and timerThomas Petazzoni2014-04-261-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit switches the Orion5x platforms described through DT to use a DT-defined interrupt controller and timer. This involves: * Describing in the DT the bridge interrupt controller, which is a child interrupt controller to the main one, which is used for timer and watchdog interrupts. * Describing in the DT the timer. * Adding in the DT the interrupt specifications for the watchdog. * Selecting the ORION_IRQCHIP and ORION_TIMER drivers to be compiled. * Change board-dt.c to no longer have an ->init_time() callback, since the default callback will work fine: it calls clocksource_of_init() and of_clk_init(), as needed. * Implement a multi-IRQ handler for non-DT platforms in mach-orion5x/irq.c.

* ARM: orion5x: convert to use 'clocks' property for UART controllersThomas Petazzoni2014-04-261-2/+2
| | | | | | | | | | | | | | | | Until the previous commit, the Orion5x clocks were not described in the Device Tree. Now that they are described in the Device Tree, we can replace the manual 'clock-frequency' property in the UART nodes by a nicer 'clocks' reference in those UART nodes. This commit consequently removes the 'clock-frequency' property from the LaCie edmini_v2 board, which is at this point the only Orion5x board converted to the Device Tree.

* ARM: orion5x: convert DT to use the mvebu-mbus driverThomas Petazzoni2014-04-261-119/+126
| | | | | | | | | | | | | | | | | | | | | | | | | This commit switches the Orion5x Device Tree files to use the DT representation and probing for the mvebu-mbus driver. The changes are mainly: * Re-organize the DT to follow the same organization as the one used on Armada 370/XP, which is needed for mvebu-mbus to work: a top-level soc { ... } node, which corresponds to the MBus bus, and a sub-node internal-regs { ... } for all peripherals whose register sit only in the "Internal Register Window". This change re-indents by one level the definition of all nodes in the Device Tree, which explains the large change. * Use custom functions orion5x_dt_init_early() and orion5x_dt_init_time() instead of orion5x_init_early() and orion5x_timer_init() as we now want the MBus driver to be probed from the Device Tree. We still use the old-style timer initialization, but that will be changed in a followup commit.

* ARM: orion5x: move interrupt controller node into ocpThomas Petazzoni2014-04-261-7/+7
| | | | | | | | | | | | | | | | The interrupt controller node was located outside of the ocp@f1000000 node, which doesn't make much sense: like any other device, the interrupt controller has registers located in the "Internal Registers Window", so it is much more logical to have it under the ocp@f1000000 node. It is even more important as we are going to move Orion5x to use the Device Tree binding of the mvebu-mbus driver.

| * dt/bindings: remove device_type "network" referencesGrant Likely2014-01-161-1/+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.

| | | | | | | | | | | | Future irqchip driver for Orion SoCs has a modified reg layout starting from CAUSE register. The former DT irq driver stub just used what the non-DT driver wants. Currently, orion5x is not ready for irqchip driver because of legacy timer and missing DT clk provider. To ease future conversion and just because orion-intc binding documentation already reflects new reg layout, we convert orion5x DT now.
