dt: introduce for_each_available_child_of_node, of_get_next_available_child

2012-08-20T09:16:00Z

Macro for_each_child_of_node() makes it easy to iterate over all of the children for a given device tree node, including those nodes that are marked as unavailable (i.e. status = "disabled"). Introduce for_each_available_child_of_node(), which is like for_each_child_of_node(), but it automatically skips unavailable nodes. This also requires the introduction of helper function of_get_next_available_child(), which returns the next available child node. Signed-off-by: Timur Tabi Signed-off-by: David S. Miller

Pull irqdomain changes from Grant Likely: "Round of refactoring and enhancements to irq_domain infrastructure. This series starts the process of simplifying irqdomain. The ultimate goal is to merge LEGACY, LINEAR and TREE mappings into a single system, but had to back off from that after some last minute bugs. Instead it mainly reorganizes the code and ensures that the reverse map gets populated when the irq is mapped instead of the first time it is looked up. Merging of the irq_domain types is deferred to v3.7 In other news, this series adds helpers for creating static mappings on a linear or tree mapping." * tag 'irqdomain-for-linus' of git://git.secretlab.ca/git/linux-2.6: irqdomain: Improve diagnostics when a domain mapping fails irqdomain: eliminate slow-path revmap lookups irqdomain: Fix irq_create_direct_mapping() to test irq_domain type. irqdomain: Eliminate dedicated radix lookup functions irqdomain: Support for static IRQ mapping and association. irqdomain: Always update revmap when setting up a virq irqdomain: Split disassociating code into separate function irq_domain: correct a minor wrong comment for linear revmap irq_domain: Standardise legacy/linear domain selection irqdomain: Make ops->map hook optional irqdomain: Remove unnecessary test for IRQ_DOMAIN_MAP_LEGACY irqdomain: Simple NUMA awareness. devicetree: add helper inline for retrieving a node's full name

Pull PWM subsystem from Thierry Reding: "The new PWM subsystem aims at collecting all implementations of the legacy PWM API and to eventually replace it completely. The subsystem has been in development for over half a year now and many drivers have already been converted. It has been in linux-next for a couple of weeks and there have been no major issues so I think it is ready for inclusion in your tree." Arnd Bergmann : "Very much Ack on the new subsystem. It uses the interface declarations as the previously separate pwm drivers, so nothing changes for now in the drivers using it, although it enables us to change those more easily in the future if we want to. This work is also one of the missing pieces that are required to eventually build ARM kernels for multiple platforms, which is currently prohibited (amongs other things) by the fact that you cannot have more than one driver exporting the pwm functions."

of: Improve prom_update_property() function

2012-07-11T05:26:51Z

prom_update_property() currently fails if the property doesn't actually exist yet which isn't what we want. Change to add-or-update instead of update-only, then we can remove a lot duplicated lines.

devicetree: add helper inline for retrieving a node's full name

2012-07-06T12:16:34Z

The pattern (np ? np->full_name : "") is rather common in the kernel, but can also make for quite long lines. This patch adds a new inline function, of_node_full_name() so that the test for a valid node pointer doesn't need to be open coded at all call sites.

irqdomain: Simple NUMA awareness.

2012-06-15T18:08:00Z

While common irqdesc allocation is node aware, the irqdomain code is not. Presently we observe a number of regressions/inconsistencies on NUMA-capable platforms: - Platforms using irqdomains with legacy mappings, where the irq_descs are allocated node-local and the irqdomain data structure is not. - Drivers implementing irqdomains will lose node locality regardless of the underlying struct device's node id. This plugs in NUMA node id proliferation across the various allocation callsites by way of_node_to_nid() node lookup. While of_node_to_nid() does the right thing for OF-capable platforms it doesn't presently handle the non-DT case. This is trivially dealt with by simply wraping in to numa_node_id() unconditionally.
