* arm/tegra: rename board-dt.c to board-dt-tegra20.cPeter De Schrijver2011-12-171-148/+0
| | | | | | | | | | | Tegra20 based boards will be handled by the current board-dt.c file. Tegra30 based boards will be handled by a new board-dt-tegra30.c file. Hence rename the existing board-dt.c to board-dt-tegra20.c to reflect its use.

* | arm/tegra: convert tegra20 to GIC devicetree bindingpdeschrijver@nvidia.com2011-12-071-12/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert tegra20 IRQ intialization to the GIC devicetree binding. Modify the interrupt definitions in the dts files according to Documentation/devicetree/bindings/arm/gic.txt v3 (swarren): * Moved of_irq_init() call into board-dt.c to avoid ifdef'ing it. - Even with a dummy replacement if !CONFIG_OF, the reference from tegra_dt_irq_match[] to gic_of_init() would still have to be ifdef'd - It's plausible that tegra_dt_irq_match[] may need to contain more entries in the future, and defining what they are seems more suitable for board-dt.c than irq.c v2 (swarren): * Removed some stale GIC init code from board-dt.c * Undid some accidental 0x -> 0x0 search/replace.

* arm/tegra: Don't create duplicate gpio and pinmux devicesStephen Warren2011-11-091-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | *_pinmux_init() register the GPIO and pinmux devices so that they're ready before any other device needs them. *_pinmux_init() are also called by board-dt.c in order to set up the GPIO and pinmux configurations. In this case, if we register the devices, they end up being probed once due to this registration, and a second time due to a device-tree node (or vice-versa). The second probe fails since the memory regions are already requested. Besides, we don't actually want the duplicated devices. To avoid this duplicate registration, modify *_pinmux_init() to check whether it's running on a DT machine. If not, register the pinmux devices. If so, don't register them. Finally, modify board-dt.c to call the *_pinmux_init() after all devices have been instantiated from device-tree. This allows the GPIO and pinmux devices to be instantiated and initialized before calling functions to configure the hardware. This has one disadvantage: The pinmux and GPIO initialization now happens after /all/ devices are instantiated, rather than after just gpio and pinmux but before anything else. So the correct HW configuration is not in place when e.g. the SD/MMC device is probed. Long-term, this should be solved by doing both: a) Initializing the HW state from DT nodes during GPIO and pinmux device probe. b) Using the deferred driver probe mechanism, so that drivers can defer their probe until after the gpio and pinmux drivers have probed. v2: s/int is_dt/bool is_dt/ v3: Use of_machine_is_compatible inside *_pinmux_init() rather than passing an explicit parameter into the function from outside.

* arm/dt: tegra devicetree supportGrant Likely2011-07-281-0/+119
Everything required to populate NVIDIA Tegra devices from the device tree. This patch adds a new DT_MACHINE_DESC() which matches against a tegra20 device tree. So far it only registers the on-chip devices, but it will be refined in follow on patches to configure clocks and pin IO from the device tree also.
