drivers/amba: create devices from device tree Add a function to create amba_devices (i.e. primecell peripherals) from device tree nodes. The device tree scanning is done by the of_platform_populate() function which can call of_amba_device_create based on a match table entry. Nodes with a "arm,primecell-periphid" property can override the h/w peripheral id value. Based on the original work by Jeremy Kerr.

of/device: Merge of_platform_bus_probe() Merge common code between PowerPC and microblaze. This patch merges the code that scans the tree and registers devices. The functions merged are of_platform_bus_probe(), of_platform_bus_create(), and of_platform_device_create(). This patch also move the of_default_bus_ids[] table out of a Microblaze header file and makes it non-static. The device ids table isn't merged because powerpc and microblaze use different default data.

of: Merge of_platform_bus_type with platform_bus_type of_platform_bus was being used in the same manner as the platform_bus. The only difference being that of_platform_bus devices are generated from data in the device tree, and platform_bus devices are usually statically allocated in platform code. Having them separate causes the problem of device drivers having to be registered twice if it was possible for the same device to appear on either bus. This patch removes of_platform_bus_type and registers all of_platform bus devices and drivers on the platform bus instead. A previous patch made the of_device structure an alias for the platform_device structure, and a shim is used to adapt of_platform_drivers to the platform bus. After all of of_platform_bus drivers are converted to be normal platform drivers, the shim code can be removed. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

devicetree: Add empty of_platform_populate() for !CONFIG_OF_ADDRESS (sparc) 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.

of: Allow busses with #size-cells=0 It's quite legitimate for a DT node to specify #size-cells=0. One example is a node that's used to collect a number of non-memory-mapped devices. In that scenario, there may be multiple child nodes with the same name (type) thus necessitating the use of unit addresses in node names, and reg properties: / { regulators { compatible = "simple-bus"; #address-cells = <1>; #size-cells = <0>; regulator@0 { compatible = "regulator-fixed"; reg = <0>; ... }; regulator@1 { compatible = "regulator-fixed"; reg = <1>; ... }; ... }; }; However, #size-cells=0 prevents translation of reg property values into the parent node's address space. In turn, this triggers the kernel to emit error messages during boot, such as: prom_parse: Bad cell count for /regulators/regulator@0 To prevent printing these error messages for legitimate DT content, a number of changes are made: 1) of_get_address()/of_get_pci_address() are modified only to validate the value of #address-cells, and not #size-cells. 2) of_can_translate_address() is added to indicate whether address translation is possible. 3) of_device_make_bus_id() is modified to name devices based on the translated address only where possible, and otherwise fall back to using the (first cell of the) raw untranslated address. 4) of_device_alloc() is modified to create memory resources for a device only if the address can be translated into the CPU's address space.

of: Merge of_platform_bus_type with platform_bus_type of_platform_bus was being used in the same manner as the platform_bus. The only difference being that of_platform_bus devices are generated from data in the device tree, and platform_bus devices are usually statically allocated in platform code. Having them separate causes the problem of device drivers having to be registered twice if it was possible for the same device to appear on either bus. This patch removes of_platform_bus_type and registers all of_platform bus devices and drivers on the platform bus instead. A previous patch made the of_device structure an alias for the platform_device structure, and a shim is used to adapt of_platform_drivers to the platform bus. After all of of_platform_bus drivers are converted to be normal platform drivers, the shim code can be removed. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

of/device: Rework to use common platform_device_alloc() for allocating devices The current code allocates and manages platform_devices created from the device tree manually. It also uses an unsafe shortcut for allocating the platform_device and the resource table at the same time. (which I added in the last rework; sorry). This patch refactors the code to use platform_device_alloc() for allocating new devices. This reduces the amount of custom code implemented by of_platform, eliminates the unsafe alloc trick, and has the side benefit of letting the platform_bus code manage freeing the device data and resources when the device is freed.

of: address: Don't fail a lookup just because a node has no reg property Sometimes it doesn't make any sense for a node to have an address. In this case device lookup will always be unsuccessful because we currently assume every node will have a reg property. This patch changes the semantics so that the resource address and the lookup address will only be compared if one exists. Things like AUXDATA() rely on of_dev_lookup to return the lookup entry of a particular device in order to do things like apply platform_data to a device. However, this is currently broken for nodes which do not have a reg property, meaning that platform_data can not be passed in those cases.

devicetree: Add empty of_platform_populate() for !CONFIG_OF_ADDRESS (sparc) 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.
