2011-02-28dt/net: Eliminate users of of_platform_{,un}register_driverGrant Likely
Get rid of users of of_platform_driver in drivers/net. The of_platform_{,un}register_driver functions are going away, so the users need to be converted to using the platform_bus_type directly. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2010-08-06of/device: Replace struct of_device with struct platform_deviceGrant Likely
of_device is just an alias for platform_device, so remove it entirely. Also replace to_of_device() with to_platform_device() and update comment blocks. This patch was initially generated from the following semantic patch, and then edited by hand to pick up the bits that coccinelle didn't catch. @@ @@ -struct of_device +struct platform_device Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Reviewed-by: David S.

2010-05-22of: Remove duplicate fields from of_platform_driverGrant Likely
.name, .match_table and .owner are duplicated in both of_platform_driver and device_driver. This patch is a removes the extra copies from struct of_platform_driver and converts all users to the device_driver members. This patch is a pretty mechanical change. The usage model doesn't change and if any drivers have been missed, or if anything has been fixed up incorrectly, then it will fail with a compile time error, and the fixup will be trivial. This patch looks big and scary because it touches so many files, but it should be pretty safe.

2010-05-18of: Always use 'struct device.of_node' to get device node pointer.Grant Likely
The following structure elements duplicate the information in 'struct device.of_node' and so are being eliminated. This patch makes all readers of these elements use device.of_node instead.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
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.

So far, MPC512x used mpc512x_find_ips_freq() to get the bus frequency, while MPC52xx used mpc52xx_find_ipb_freq(). Despite the different clock names (IPS vs. IPB) the code was identical.

2009-04-27net: Rework mpc5200 fec driver to use of_mdio infrastructure.Grant Likely
The patch reworks the MPC5200 Fast Ethernet Controller (FEC) driver to use the of_mdio infrastructure for registering PHY devices from data out openfirmware device tree, and eliminates the assumption that the PHY for the FEC is always attached to the FEC's own MDIO bus. With this patch, the FEC can use a PHY attached to any MDIO bus if it is described in the device tree.

2008-04-03[POWERPC] Fix MPC5200 (not B!) device tree so FEC ethernet worksRené Bürgel
This gets the FEC ethernet driver working again on the lite5200 platform. The FEC driver is also compatible with the MPC5200, not only with the MPC5200B, so this adds a suitable entry to the driver's match list. Furthermore this adds the settings for the PHY in the dts file for the Lite5200. Note, that this is not exactly the same as in the Lite5200B, because the PHY is located at f0003000:01 for the 5200, and at :00 for the 5200B. This was tested on a Lite5200 and a Lite5200B, both booted a kernel via tftp and mounted the root via nfs successfully.
