| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GPIO line setup In case of Amstrad Delta modem utilized GPIO line, interrupt is requested from standard serial8250 driver code without first requesting the GPIO pin itself. Even if it works with default OMAP GPIO interrupt handler, it appeared not compatible with recent, optimized version of the board GPIO FIQ handler, required for fast processing of interrupts generated by other GPIO pin that a serial keyboard clock hangs off. This patch fills the board specific modem initialization routine with common GPIO line reservation and direction setup.

The handler's purpose is to process interrupts generated by a GPIO line that a serial keyboard clock hangs off. It collects consecutive bits into words, pushing them into a buffer, then requests a higher level interrupt after one or more words are ready for further processing by a keyboard port driver. The handler also processes interrupts generated by two other GPIO lines, used by other on-board supported devices, by simply requesting a higher level interrupt, that in turn should invoke those device's specific irq handlers. IRQ12 line, not used by OMAP1510 hardware (described as reserved), has been choosen as a higher level interrupt source.

* | | omap: Use a memory address for storing the debug port info instead of UART1 ↵Tony Lindgren2010-05-031-15/+6
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | scratchpad This removes the dependency to the UART1 being available for storing the debug configuration in uncompress.h. This will simplify the DEBUG_LL UART configuration for boards that may not have UART1, or have an external UART as it requires only one mapping for DEBUG_LL. The patch has a few limitations. Basically now we're assuming that the kernel uncompress code won't overlap with OMAP_UART_INFO. We also assume the printascii is called at least once before paging_init in order for addruart to have a chance to read the UART setup from OMAP_UART_INFO. As suggested by Cyril Chemparathy <cyril@ti.com>, Vikram Pandita <vikram.pandita@ti.com> and Kevin Hilman <khilman@deeprootsystems.com>.

* | 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.

* OMAP clock: drop RATE_FIXED clock flagPaul Walmsley2010-02-242-20/+10
| | | | | | | | | | | | | | | | | | The RATE_FIXED clock flag is pointless. In the OMAP1 clock code, it simply causes the omap1_clk_round_rate() function to return the current rate of the clock. omap1_clk_round_rate(), however, should never be called for a fixed-rate clock, since none of these clocks have a .round_rate function pointer set in their struct clk records. Similarly, in the OMAP2+ clock code, the RATE_FIXED flag just causes the clock code to emit a warning if the OMAP clock maintainer was foolish enough to add a .round_rate function pointer to a fixed-rate clock. "Doctor, it hurts when I pretend that a fixed-rate clock is rate-changeable." "Then don't pretend that a fixed-rate clock is rate-changeable." It has no functional value. This patch drops the RATE_FIXED clock flag, removing it from all clocks that are so marked. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Richard Woodruff <r-woodruff2@ti.com>

These are overzealous and are more difficult to maintain when the clock tree is in a separate namespace, so, remove them. Signed-off-by: Paul Walmsley <paul@pwsan.com>
* OMAP: OMAPFB: split omapfb.hTomi Valkeinen2009-12-091-1/+1
| | | | | | | | | | | | | | Split arch/arm/plat-omap/include/mach/omapfb.h into two files: include/linux/omapfb.h - ioctls etc for userspace and some kernel stuff for board files drivers/video/omap/omapfb.h - for omapfb internal use This cleans up omapfb.h and also makes it easier for the upcoming new DSS driver to co-exist with the old driver.

* omap1: omap_udc: Add clocking and disable vbus sense for omap7xxCory Maccarrone2009-11-223-1/+13
| | | | | | | | | | | | | | | | | | | | The l3_ocpi_ck clock is needed on omap7xx processors for USB. Additionally, bit 8 of the SOFT_REQ_REG needs to be enabled for the usb_dc_ck on omap7xx, which is a different bit than that of the omap16xx-defined clock of the same name. I added a provision for the usb_dc_ck and l3_ocpi_ck clocks as dc_clk and hhc_clk, respectively, for omap7xx CPUs. Additionally, I added a check in machine_without_vbus_sense for all omap7xx devices, as presently I know of no omap7xx-based devices that have vbus sense, and it made more sense to me to use a cpu check here than to spell out each machine one at a time. Finally, DMA is disabled for omap7xx, as it causes problems with these chips.

* omap1: mmc: Add platform init for omap7xxCory Maccarrone2009-11-224-5/+30
| | | | | | | | | | | | | | | | | | | | | | The MMC mux pins normally used by omap chips in devices.c are different from what is needed by omap7xx chips. This change adds a conditional around the mux setup code to enable the correct mux pins. The omap730 and omap850 both use a different clock for the "fck" clock of the MMC interface than other omap processors based on the SOFT_REQ_REG, pin 12. The "ick" clock is the same as that used by other omap processors. * Added the missing clock definition as mmc3_ck to clock.h * Added the clock definition to omap_clks in clock.c * Added CK_7XX to the mmci-omap.0 "ick" clock already in clock.c With these changes, it is now possible to initialize and use MMC cards with omap730 and omap850 devices.

* omap: Eliminate OMAP_MAX_NR_PORTSAlexander Shishkin2009-11-221-1/+1
| | | | | | | | | | | | | | | | | | | | Eliminate OMAP_MAX_NR_PORTS Note that also the null terminator entry for omap1 serial_platform_data needs to be now removed to avoid oopsing. Note that mach-omap1 uses struct plat_serial8250_port array, which requires a null terminator at the end, and that's why we need to use ARRAY_SIZE - 1. This is not needed on mach-omap2 as the array used is struct omap_uart_state, and does not use a null terminator.
