* powerpc/86xx: don't pretend that we support 8-bit pixels on the MPC8610 HPCDTimur Tabi2011-05-19
| | | | | | | | | | | | | | If the video mode is set to 16-, 24-, or 32-bit pixels, then the pixel data contains actual levels of red, blue, and green. However, if the video mode is set to 8-bit pixels, then the 8-bit value represents an index into color table. This is called "palette mode" on the Freescale DIU video controller. The DIU driver does not currently support palette mode, but the MPC8610 HPCD board file returned a non-zero (although incorrect) pixel format value for 8-bit mode.

* powerpc/smp: smp_ops->kick_cpu() should be able to failMichael Ellerman2011-04-20
| | | | | | | | | | | | | When we start a cpu we use smp_ops->kick_cpu(), which currently returns void, it should be able to fail. Convert it to return int, and update all uses. Convert all the current error cases to return -ENOENT, which is what would eventually be returned by __cpu_up() currently when it doesn't detect the cpu as coming up in time.

* | 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.

* 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: FPGA support for GE Fanuc SBC610Martyn Welch2008-10-13
| | | | | | | | | | | Support for the SBC610 VPX Single Board Computer from GE Fanuc (PowerPC MPC8641D). This patch adds support for the registers held in the devices main FPGA, exposing extra information about the revision of the board through cpuinfo.

* powerpc: remove support for bootmem-allocated memory for the DIU driverTimur Tabi2008-10-13
| | | | | | | | | | Early versions of the Freescale DIU framebuffer driver depended on a bootmem allocation of memory for the video buffer. The need for this feature was removed in commit 6b51d51a, so now we can remove the platform-specific code that allocated that memory.

* powerpc: GE Fanuc's FPGA based PIC controller on the SBC610Martyn Welch2008-10-13
| | | | | | | | | | | | Support for the SBC610 VPX Single Board Computer from GE Fanuc (PowerPC MPC8641D). A number of MPC8641D based route interrupts for on-board interrupts through a FPGA based interrupt controller, which is chained with the MPC8641D's mpic. This patch provides a basic driver to allow basic routing of interrupts to the mpic. Signed-off-by: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | Support for the SBC610 VPX Single Board Computer from GE Fanuc (PowerPC MPC8641D). Fixup to correctly reconfigure USB, provided by an NEC uPD720101, after device is reset. This requires a set of chip specific registers in the devices configuration space to be correctly written, enabling all ports and switching the device to use an external 48-MHz Oscillator.

This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where <asm-powepc/...> was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc/85xx/86xx: some refactoring for fsl_uli1575 codeAnton Vorontsov2008-07-16
| | | | | | | | | | | | - Get rid of uses_fsl_uli_m1575, it does not scale for all cases. Instead, let's explicitly use machine_is() for each fixup. - Factor out MPC8610HPCD quirks to fsl_uli1575, and protect them with machine_is(). One step closer to multiplatform kernels. - Actually use fsl_uli1575 on MPC8610HPCD, so RTC quirk will be applied. - RTC quirk applies to all boards though, so no machine_is() checks.
