| * of/flattree: Fix unhandled OF_DT_NOP tag when unflattening the device treeJason Gunthorpe2010-03-261-2/+5
| | | | | | | | | | | | | | | | | | | | | | NOPs within the property section are skipped, but NOPs between OF_DT_END_NODE and OF_DT_BEGIN_NODE were not. My firmware NOPs out entire nodes depending on various environment parameters. of_scan_flat_dt already handles NOP more generally.

* | include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-302-0/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* of/flattree: Make the kernel accept ePAPR style phandle informationDavid Gibson2010-02-091-1/+10
| | | | | | | | | | | Currently when processing flattened device trees, the kernel expects the phandle in a property called "linux,phandle". The ePAPR spec - not being Linux specific - instead requires phandles to be encoded in a property named simply "phandle".

| | | | | | | | | | | | | | | | Properties in the device tree are specified as big-endian. At present, the only platforms to support device trees are also big-endian, so we've been acessing the properties as raw values. We'd like to add device tree support to little-endian platforms too, so add endian conversion to the sites where we access property values in the common of code.

* of/flattree: use callback to setup initrd from /chosenJeremy Kerr2010-02-091-16/+11
| | | | | | | | | | | | | | | | | | | At present, the fdt code sets the kernel-wide initrd_start and initrd_end variables when parsing /chosen. On ARM, we only set these once the bootmem has been reserved.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In struct device_node, the phandle is named 'linux_phandle' for PowerPC and MicroBlaze, and 'node' for SPARC. There is no good reason for the difference, it is just an artifact of the code diverging over a couple of years. This patch renames both to simply .phandle. Note: the .node also existed in PowerPC/MicroBlaze, but the only user seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't look like the assignment between .linux_phandle and .node is significantly different enough to warrant the separate code paths unless ibm,phandle properties actually appear in Apple device trees. I think it is safe to eliminate the old .node property and use phandle everywhere. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

| | | | | | | | | | | | | | | | | Fixed-link support is broken for the ucc_eth, gianfar, and fs_enet device drivers. The "OF MDIO rework" patches removed most of the support. Instead of re-adding fixed-link stuff to the drivers, this patch adds a support function for parsing the fixed-link property and obtaining a dummy phy to match. Note: the dummy phy handling in arch/powerpc is a bit of a hack and needs to be reworked. This function is being added now to solve the regression in the Ethernet drivers, but it should be considered a temporary measure until the fixed link handling can be reworked.

* drivers/of: Add the of_find_i2c_device_by_node function.Jon Smirl2009-01-091-0/+19
| | | | | | | | | | | | | The of_find_i2c_device_by_node function allows you to follow a reference in the device tree to an i2c device node and then locate the linux device instantiated by the device tree. Example use: an I2S bus driver finding the i2c_device instance for a codec described by a device tree node. This was waiting for Anton's i2c patches that were just added.

* of: of_parse_phandles_with_args() learns to differentiate 'hole' cellsAnton Vorontsov2008-12-211-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | Given this list (contains three gpio specifiers, one of which is a hole): gpios = <&phandle1 1 2 3 0 /* a hole */ &phandle2 4 5 6>; of_parse_phandles_with_args() would report -ENOENT for the `hole' specifier item, the same error value is used to report the end of the list, for example. Sometimes we want to differentiate holes from real errors -- for example when we want to count all the [syntax correct] specifiers. With this patch of_parse_phandles_with_args() will report -EEXITS when somebody requested to parse a hole. Also, make the out_{node,args} arguments optional, when counting we don't really need the out values.
