| * of: Add a context pointer to fixup functionsSascha Hauer2013-11-061-1/+1
| | | | | | | | | | | | | | If drivers want to fixup their specific instance they need some context to know which instance they have to fixup. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | of: simplify phandle lookupSascha Hauer2013-10-221-1/+0
|/ | | | | | | | | Instead of populating an extra list containing all phandles just iterate over the whole tree. This is done as preparation for more dynamic devicetrees where parts are loaded at runtime. Here we don't want to keep the list of phandles in sync.

* of: base: import of_find_node_by_typeRenaud Barbier2013-09-051-0/+2
| | | | | | | | | | | | Import of_find_node_by_type from Linux drivers/of/base.c - commit id d8dfad3. This function retrieves a node pointer based on the "device_type" property of the node. This is used by device tree update functions in PPC support. Signed-off-by: Renaud Barbier <renaud.barbier@ge.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* of: introduce some new helpersSascha Hauer2013-08-141-0/+14
| | | | | | | | | | | of_get_tree_max_phandle - get the maximum phandle of a tree. Needed for creating new phandles without conflicts. of_node_create_phandle - create a phandle for a node which doesn't have one. of_find_node_by_alias - find a node by alias name of_find_node_by_path_or_alias - find a node by full path or alias name of_find_root_node - find the root node for a given device node Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Add configurability via devicetreeSascha Hauer2013-07-181-0/+2
| | | | | | | | | | | | | | | | | | This adds the possibility to configure the place for the environment from the devicetree and to partition devices from the devicetree. Configuration has the general form of devices with a regular compatible property. This allows to later add additional drivers or drivers with different behaviour (for example to add support for redundant environment). The configuration is all in the /chosen/barebox/ hierarchy of the devicetree. This separates the configuration from the hardware description. Also it makes it possible to store the configuration in a completely separate devicetree (or devicetree overlay). For the same reason all configuration is done using nodepathes rather than phandles.

* of: Add convenience functions to en/disable devicenodesSascha Hauer2013-07-181-0/+5

* OF: base: rename of_free to of_delete_nodeSebastian Hesselbarth2013-07-051-2/+2
| | | | | | | | | of_free is misleading about the actual purpose of the function. There is already a of_create_node counterpart, so rename of_free to of_create_node and update all users accordingly.

* OF: remove device and resource pointer from struct device_nodeSebastian Hesselbarth2013-07-051-3/+0
| | | | | | | | | struct device_node has its own resources and a pointer to associated device_d. With recent platform related OF code, we can convert the only user of it and remove those pointers from struct device_node.

* OF: gpio: convert DT based gpio handling to new OF APISebastian Hesselbarth2013-07-051-3/+0
| | | | | | | | | | | This creates a Linux OF API compatible counterpart of of_get_named_gpio_flags. Existing of_get_named_gpio is converted to a static inline function, which is in the corresponding of_gpio.h include. While at it, drivers/of/gpio.c is also renamed to drivers/of/of_gpio.c to follow the of_ prefix naming scheme. The new include is also added to existing users of of_get_named_gpio.

* OF: convert of_translate_address to new APISebastian Hesselbarth2013-07-051-2/+0
| | | | | | | | | | This converts existing of_translate_address to recently added API. In contrast to existing behavior, the new function honors ranges properties properly. It now allows reg properties to be set as offset with respect to the correspoding parent node.

* OF: base: rename of_node_disabled to of_device_is_availableSebastian Hesselbarth2013-06-201-0/+6
| | | | | | | | | | | According to ePAPR 1.1 spec, device tree nodes status can be either "okay", "disabled", "fail", or "fail-sss". Barebox already has a function to check for "disabled" nodes, while Linux checks for "okay" or "ok". To synchronize Barebox and Linux OF APIs, rename of_node_disabled to of_device_is_available and check for "okay" instead of "disabled" as it also makes "fail"ed devices unavailable.

* OF: base: sync of_find_node_by_path with linux OF APISebastian Hesselbarth2013-06-201-2/+15
| | | | | | | | | | | | | Barebox of_find_node_by_path requires a node to be passed as start node to start searching. Linux OF API does not pass this node and no current user of it in barebox is passing anything else than the root node. Therefore, we rename current function to of_find_node_by_path_from and introduce a Linux OF API compatible of_find_node_by_path that always passes the current root_node. Also, all current users of that function are updated to reflect the API change.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch separates out the "generic" memory segment registration function (of_add_memory_bank()) from of_add_memory(). The MIPS architecture has different view on memory resources than the ARM and PPC architectures so the "generic" of_add_memory_bank() is unusable for the MIPS architecture.
