| | | | | | | | | | | | | | | | | | | | | | TWL4030 depends on IRQ_DOMAIN support, so this patch selects it in Kconfig.

| * devicetree: Add empty of_platform_populate() for !CONFIG_OF_ADDRESS (sparc)Grant Likely2012-02-26
| | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | irq_domain_add_simple() was a stop-gap measure until complete irq_domain support was complete. This patch removes the irq_domain_add_simple() interface. This patch also drops the explicit irq_domain initialization performed by the mach-versatile code because the versatile interrupt controller already has irq_domain support built into it. This was a bug that was hanging around quietly for a while, but with the full irq_domain which actually verifies that irq_domain ranges are available it would cause the registration to fail and the system wouldn't boot. v4: Fixed number of irqs in mx5 gpio code v2: Updated to pass in host_data pointer on irq_domain allocation.

| * irq_domain: Add support for base irq and hwirq in legacy mappingsGrant Likely2012-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for a legacy mapping where irq = (hwirq - first_hwirq + first_irq) so that a controller driver can allocate a fixed range of irq_descs and use a simple calculation to translate back and forth between linux and hw irq numbers. This is needed to use an irq_domain with many of the ARM interrupt controller drivers that manage their own irq_desc allocations. Ultimately the goal is to migrate those drivers to use the linear revmap, but doing it this way allows each driver to be converted separately which makes the migration path easier. This patch generalizes the IRQ_DOMAIN_MAP_LEGACY method to use (first_irq-first_hwirq) as the offset between hwirq and linux irq number, and adds checks to make sure that the hwirq number does not exceed range assigned to the controller.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each revmap type has different arguments for setting up the revmap. This patch splits up the generator functions so that each revmap type can do its own setup and the user doesn't need to keep track of how each revmap type handles the arguments. This patch also adds a host_data argument to the generators. There are cases where the host_data pointer will be needed before the function returns. ie. the legacy map calls the .map callback for each irq before returning. v2: - Add void *host_data argument to irq_domain_add_*() functions - fixed failure to compile - Moved IRQ_DOMAIN_MAP_* defines into irqdomain.c Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Cc: Rob Herring <rob.herring@calxeda.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Milton Miller <miltonm@bga.com> Tested-by: Olof Johansson <olof@lixom.net>

| * irq_domain: Move irq_domain code from powerpc to kernel/irqGrant Likely2012-02-16
| | | | | | | | | | | | | | | | | | | | | | This patch only moves the code. It doesn't make any changes, and the code is still only compiled for powerpc. Follow-on patches will generalize the code for other architectures.
