This returns the allocate memory chunk, storing the unflattened device tree, from of_fdt_unflatten_tree() so that memory chunk can be released on demand in PowerNV PCI hotplug driver. Signed-off-by:

This adds one more argument to of_fdt_unflatten_tree() to specify the parent node of the FDT blob that is going to be unflattened. In the result, the function can be used to unflatten FDT blob that represents device sub-tree in PowerNV PCI hotplug driver. Cc: Jyri Sarha <jsarha@ti.com> Signed-off-by:

This renames unflatten_dt_node() to unflatten_dt_nodes() as it populates multiple device nodes from FDT blob. No logical changes introduced. Signed-off-by:

Gavin Shan authored
In current implementation, unflatten_dt_node() is called recursively to unflatten device nodes in FDT blob. It's stress to limited stack capacity, especially to adopt the function to unflatten device sub-tree that possibly has multiple root nodes. In that case, we runs out of stack and the system can't boot up successfully. In order to reuse the function to unflatten device sub-tree, this avoids calling the function recursively, meaning the device nodes are unflattened in one call on unflatten_dt_node(): two arrays are introduced to track the parent path size and the device node of current level of depth, which will be used by the device node on next level of depth to be unflattened. All device nodes in more than 64 level of depth are dropped and hopefully, the system can boot up successfully with the partial device-tree. Also, the parameter "poffset" and "fpsize" are unused and dropped and the parameter "dryrun" is figured out from "mem == NULL". Besides, the return value of the function is changed to indicate the size of memory consumed by the unflatten device tree or error code. Signed-off-by:

The function unflatten_dt_node() is called recursively to unflatten device nodes and properties in the FDT blob. It looks complicated and hard to be understood. This splits the function into 3 functions: populate_properties(), populate_node() and unflatten_dt_node(). populate_properties(), which is called by populate_node(), creates properties for the indicated device node. The later one creates the device nodes from FDT blob. populate_node() gets the offset in FDT blob for next device nodes and then calls populate_node(). No logical changes introduced. Signed-off-by:

When CONFIG_OF is disabled, we have to include linux/errno.h before including of_graph.h, or get build errors like in the newly added sun4i drm driver: In file included from ../drivers/gpu/drm/sun4i/sun4i_drv.c:14:0: include/linux/of_graph.h: In function 'of_graph_parse_endpoint': include/linux/of_graph.h:58:10: error: 'ENOSYS' undeclared (first use in this function) A better solution is to ensure that the header can be included by itself, so let's include linux/errno.h here to fix the error we just got, and any similar future error.

Device tree binding for NVIDIA Tegra have traditionally carried the "nvidia," vendor prefix in the filename. A couple of odd ones don't, so fix them up for consistency. Also rename existing bindings to reflect the first compatible value that they document. This wasn't done consistently either. Acked-by:

When Tegra124 support was first merged the unit-addresses of all devices were listed with a "0," prefix to encode the reg property's second cell. It turns out that this notation is not correct, and the "," separator is only used to separate fields in the unit address (such as the device and function number in PCI devices), not individual cells for addresses with more than one cell.

With this macro any user can easily iterate over a list of phandles. The patch also converts __of_parse_phandle_with_args() to make use of the macro. The of_count_phandle_with_args() function is not converted, because the macro hides the return value of of_phandle_iterator_init(), which is needed in there. Signed-off-by:
