* sbc834x: put full compat string in board match checkPaul Gortmaker2012-01-04
| | | | | | | | | | | | | | | The commit 883c2cfc8bcc0fd00c5d9f596fb8870f481b5bda: "fix of_flat_dt_is_compatible() to match the full compatible string" causes silent boot death on the sbc8349 board because it was just looking for 8349 and not 8349E -- as originally there were non-E (no SEC/encryption) chips available. Just add the E to the board detection string since all boards I've seen were manufactured with the E versions.

* powerpc/83xx: make mpc830x_rdb use mpc83xx_setup_pciDmitry Eremin-Solenikov2011-11-24
| | | | | | | | | | | Traditionally mpc830x_rdb board file searched for mpc8308-pcie devices. However both in-kernel dts from the beginning declared those pcie units as compatible with mpc8314-pci, which is handled by mpc83xx_setup_pci().

| | | | | | | | | | | | | | | Commit b826291c, "drivercore/dt: add a match table pointer to struct device" added an of_match pointer to struct device to cache the of_match_table entry discovered at driver match time. This was unsafe because matching is not an atomic operation with probing a driver. If two or more drivers are attempted to be matched to a driver at the same time, then the cached matching entry pointer could get overwritten. This patch reverts the of_match cache pointer and reworks all users to call of_match_device() directly instead. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

The override table was needed originally because spi and i2c drivers had no way to do of-style matching. Now that all devices can have an of_node pointer, and all drivers can have an of_match_table, the explicit override table is no longer needed because each driver can specify its own OF-style match data.

| * of/gpio: stop using device_node data pointer to find gpio_chipGrant Likely2010-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the kernel uses the struct device_node.data pointer to resolve a struct gpio_chip pointer from a device tree node. However, the .data member doesn't provide any type checking and there aren't any rules enforced on what it should be used for. There's no guarantee that the data stored in it actually points to an gpio_chip pointer. Instead of relying on the .data pointer, this patch modifies the code to add a lookup function which scans through the registered gpio_chips and returns the gpio_chip that has a pointer to the specified device_node.

| * of/gpio: Kill of_gpio_chip and add members directly to gpio_chipAnton Vorontsov2010-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OF gpio infrastructure is great for describing GPIO connections within the device tree. However, using a GPIO binding still requires changes to the gpio controller just to add an of_gpio structure. In most cases, the gpio controller doesn't actually need any special support and the simple OF gpio mapping function is more than sufficient. Additional, the current scheme of using of_gpio_chip requires a convoluted scheme to maintain 1:1 mappings between of_gpio_chip and gpio_chip instances. If the struct of_gpio_chip data members were moved into struct gpio_chip, then it would simplify the processing of OF gpio bindings, and it would make it trivial to use device tree OF connections on existing gpiolib controller drivers. This patch eliminates the of_gpio_chip structure and moves the relevant fields into struct gpio_chip (conditional on CONFIG_OF_GPIO). This move simplifies the existing code and prepares for adding automatic device tree support to existing drivers.

* | of: Remove duplicate fields from of_platform_driverGrant Likely2010-05-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | .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.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* powerpc/83xx/suspend: Clear deep_sleeping after devices resumeAnton Vorontsov2009-12-10
| | | | | | | | | | | | | | | Currently 83xx PMC driver clears deep_sleeping variable very early, before devices are resumed. This makes fsl_deep_sleep() unusable in drivers' resume() callback. Sure, drivers can store fsl_deep_sleep() value on suspend and use the stored value on resume. But a better solution is to postpone clearing the deep_sleeping variable, i.e. move it into finish() callback.

| | | | | | | | | | | | | Commit 87ec0e98cfdd8b68da6a7f9e70142ffc0e404fbb in kumar's next branch broke one of my test configs since it looks like Anton forgot about that mpc832x_rdb platform which still uses the old style probing for the SPI stuff. I'll let them do a cleaner fix that probably involves changing the probing method and getting rid of the platform device but for now this will do to fix it.

| | | | | | | | | | | | | | | | Actually, the support is already there, but it requires newer U-Boots (to fill-in clock-frequency, and setup pin multiplexing). Though, it appears that on RDB boards USBB pins aren't multiplexed between USB and eSDHC (unlike MDS boards, where USB and eSDHC share pctl and pwrfault pins). So, for RDB boards we can safely setup pinmux and manually fill-in clock-frequency, thus making eSDHC work even with older u-boots.

* powerpc/mpc83xx: Fix usb mux setup for mpc834xPeter Korsgaard2009-06-15
| | | | | | | | | | | | | | | | | | | | | | usb0 and usb1 mux settings in the sicrl register were swapped (twice!) in mpc834x_usb_cfg(), leading to various strange issues with fsl-ehci and full speed devices. The USB port config on mpc834x is done using 2 muxes: Port 0 is always used for MPH port 0, and port 1 can either be used for MPH port 1 or DR (unless DR uses UTMI phy or OTG, then it uses both ports) - See 8349 RM figure 1-4.. mpc8349_usb_cfg() had this inverted for the DR, and it also had the bit positions of the usb0 / usb1 mux settings swapped. It would basically work if you specified port1 instead of port0 for the MPH controller (and happened to use ULPI phys), which is what all the 834x dts have done, even though that configuration is physically invalid. Instead fix mpc8349_usb_cfg() and adjust the dts files to match reality. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
