2012-03-05ARM: OMAP2+: Remove extra ifdefs for board-genericTony Lindgren1-44/+32
We need just one ifdef for each ARCH_OMAP2/3/4. Also remove the comment about i2c & twl driver as it's pretty obvious that we still need some platform data until drivers are converted to device tree. Signed-off-by: Tony Lindgren <tony@atomide.com>
2012-03-05ARM: OMAP2+: Fix build error when only ARCH_OMAP2/3 or 4 is selectedTony Lindgren1-0/+7
Otherwise we'll get undefined reference to `gic_of_init' or undefined reference to `omap_intc_of_init'. This was caused by commit fbf75da733e82bb17a01e1b907b0e40d9c028823 (ARM: OMAP2+: board-generic: Use of_irq_init API). Signed-off-by: Tony Lindgren <tony@atomide.com>
2012-02-27ARM: OMAP2+: board-generic: Use of_irq_init APIBenoit Cousson1-14/+16
Use the of_irq_init API introduced in 3.2 to handle interrupt-controller with DT. Update the irq_match table to map the proper XXX_of_init functions for INTC and GIC drivers.

2012-02-27arm/dts: OMAP3: Add interrupt-controller bindings for INTCBenoit Cousson1-2/+4
Update the DTS with the proper information required by the INTC bindings. - Add the number of interrupt lines - Add the reg and the compatible entries. Signed-off-by: Benoit Cousson <b-cousson@ti.com> Acked-by: Rob Herring <rob.herring@calxeda.com> Acked-by: Grant Likely <grant.likely@secretlab.ca>
2012-02-27ARM: OMAP2/3: intc: Add DT support for TI interrupt controllerBenoit Cousson3-10/+89
Add a function to initialize the OMAP2/3 interrupt controller (INTC) using a device tree node. This version take advantage of the new irq_domain_add_legacy API. Replace some printk() with the proper pr_ macro.

2012-02-26mfd: twl-core: Add IRQ_DOMAIN dependencyGrant Likely1-0/+1
TWL4030 depends on IRQ_DOMAIN support, so this patch selects it in Kconfig. It used to be that CONFIG_IRQ_DOMAIN must only be selected by the architecture, but recent cleanups have fixed it so that it is safe to select from anywhere.

2012-02-26devicetree: Add empty of_platform_populate() for !CONFIG_OF_ADDRESS (sparc)Grant Likely3-7/+14
Sparc has its own helpers for translating address ranges when the device tree is parsed at boot time, and it isn't able to use of_platform_populate(). However, there are some device drivers that want to use that function on other DT enabled platforms (ie. TWL4030). This patch adds an empty of_platform_populate() implementation that returns an error when CONFIG_OF_ADDRESS is not selected.

2012-02-26irq_domain: Centralize definition of irq_dispose_mapping()Grant Likely4-22/+7
Several architectures define their own empty irq_dispose_mapping(). Since the irq_domain code is centralized now, there is little need to do so. This patch removes them and creates a new empty copy when !CONFIG_IRQ_DOMAIN is selected. The patch also means that IRQ_DOMAIN becomes selectable on all architectures.
