* mtd: atmel_nand: replace cpu_is_at32ap7000() with a nand platform dataJosh Wu2013-08-051-0/+3
| | | | | | | | | | | | | | | | The nand driver use cpu_is_at32ap7000() macro for a workaround. For the multi-platform support, we will remove this cpu_is_xxx() macro. This patch adds a boolean variable need_reset_workaround in structure atmel_nand_data. Using this variable we can remove cpu_is_at32ap7000() macro.

* ARM: at91/avr32/atmel_lcdfb: add platform device-id tableJohan Hovold2013-03-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add platform device-id table in order to identify the controller and determine its configuration. The currently used configuration parameters are: have_alt_pixclock - SOC uses an alternate pixel-clock calculation formula (at91sam9g45 non-ES) have_hozval - SOC has a HOZVAL field in LCDFRMCFG which is used to determine the linesize for STN displays (at91sam9261, at921sam9g10 and at32ap) have_intensity_bit - SOC uses IBGR:555 rather than BGR:565 16-bit pixel layout (at91sam9261, at91sam9263 and at91sam9rl) This allows us to remove all the remaining uses of cpu_is macros from the driver. Tested on at91sam9263 and at91sam9g45, compile-tested for other AT91-SOCs, and untested for AVR32.

* ARM: at91/avr32/atmel_lcdfb: add bus-clock entryJohan Hovold2013-03-131-2/+2
| | | | | | | | | | | | | | | | | Add hclk entry for the atmel_lcdfb bus clock. On at91sam9261, at91sam9g10 and at32ap the bus clock has to be enabled as well as the peripheral clock. Add the appropriate lookup entries to these SOCs and fake clocks to the SOCs that do not use it. This allows us to get rid of the conditional enabling of the clocks in the driver which relied on the cpu_is macros. Tested on at91sam9263 and at91sam9g45, compile-tested for other AT91-SOCs, and untested for AVR32.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Additonally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which will cover even the most exceptional need of memory bandwidth. Together with the onboard video decoder the board is ready for video processing.

| | | | | | | | | | | | | | | | | | | | Add essential system devices, including GPIO controllers, automatically at core_initcall time. This ensures that the devices are there when the PIO driver gets initialized at postcore_initcall, fixing a bug exposed by commit d6634db8fe1784d0a8e4e156970fec034708446e "avr32: Use platform_driver_probe for pio platform driver".

|/ | | | | | | | | | | | | | The MIMC200 board uses the SPD output pin from the Ethernet MACs for other purposes. One of these is as a board-reset, so I've had to #define off the SPD output pin declaration. This is probably not the best way of achieving this, but works in the current framework.

| * atmel-mci: Add experimental DMA supportHaavard Skinnemoen2008-10-051-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for DMA transfers through the generic DMA engine framework with the DMA slave extensions. The driver has been tested using mmc-block and ext3fs on several SD, SDHC and MMC+ cards. Reads and writes work fine, with read transfer rates up to 7.5 MiB/s on fast cards with debugging disabled. Unfortunately, the driver has been known to lock up from time to time with DMA enabled, so DMA support is currently optional and marked EXPERIMENTAL. However, I didn't see any problems while testing 13 different cards (MMC, SD and SDHC of different brands and sizes), so I suspect the "Initialize BLKR before sending data transfer command" fix that was posted earlier fixed this as well.

| * atmel-mci: Platform code for supporting multiple mmc slotsHaavard Skinnemoen2008-10-051-18/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the necessary platform infrastructure to support multiple mmc/sdcard slots all at once through a single controller. Currently, the driver will use the first valid slot it finds and stick with that, but later patches will add support for switching between several slots on the fly. Extend the platform data structure with per-slot information: MMC/SDcard bus width and card detect/write protect pins. This will affect the pin muxing as well as the capabilities announced to the mmc core. Note that board code is now required to supply a mci_platform_data struct to at32_add_device_mci().

| | | | | | | | | | | | | | | | | | | | Minor cleanups for the MMC/SD support on avr32: - Make at32_add_device_mci() properly initialize "missing" platform data ... so boards like STK1002 won't try GPIO 0. - Switch over to gpio_is_valid() instead of testing for only one designated value. - Provide STK1002 platform data for the unlikely case that switches are set so first Ethernet controller isn't in use. (That's the only way to get card detect and writeprotect switch sensing on the STK1000.) And get rid of one "unused variable" warning.
