2013-07-06Merge branch 'timers-core-for-linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer core updates from Thomas Gleixner: "The timer changes contain: - posix timer code consolidation and fixes for odd corner cases - sched_clock implementation moved from ARM to core code to avoid duplication by other architectures - alarm timer updates - clocksource and clockevents unregistration facilities - clocksource/events support for new hardware - precise nanoseconds RTC readout (Xen feature) - generic support for Xen suspend/resume oddities - the usual lot of fixes and cleanups all over the place The parts which touch other areas (ARM/XEN) have been coordinated with the relevant maintainers. Though this results in an handful of trivial to solve merge conflicts, which we preferred over nasty cross tree merge dependencies. The patches which have been committed in the last few days are bug fixes plus the posix timer lot.

Cleaning up that code touches multiple subsystems, but gets rid of the dependency in the end.

2013-06-11mailbox/omap: move the OMAP mailbox framework to driversSuman Anna
The mailbox hardware (in OMAP) uses a queued mailbox interrupt mechanism that provides a communication channel between processors through a set of registers and their associated interrupt signals by sending and receiving messages. The OMAP mailbox framework/driver code is moved to be under drivers/mailbox, in preparation for adapting to a common mailbox driver framework. This allows the build for OMAP mailbox to be enabled (it was disabled during the multi-platform support). As part of the migration from plat and mach code: - Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers. - mailbox.h under plat-omap/plat/include has been split into a public and private header files. The public header has only the API related functions and types. - The module name mailbox.ko from plat-omap is changed to omap-mailbox.ko - The module name mailbox_mach.ko from mach-omapX is changed as mailbox_omap1.ko for OMAP1 mailbox_omap2.ko for OMAP2+ Cc: Tony Lindgren <tony@atomide.com> [gregkh@linuxfoundation.org: ack for staging part] Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Omar Ramirez Luna <omar.ramirez@copitl.com> Signed-off-by: Suman Anna <s-anna@ti.com>

2013-05-02ARM: OMAP: use consistent error checkingRussell King
Consistently check errors using the usual method used in the kernel for much of its history. For instance: int gpmc_cs_set_timings(int cs, const struct gpmc_timings *t) { int div; div = gpmc_calc_divider(t->sync_clk); if (div < 0) return div; static int gpmc_set_async_mode(int cs, struct gpmc_timings *t) { ... return gpmc_cs_set_timings(cs, t); ..... ret = gpmc_set_async_mode(gpmc_onenand_data->cs, &t); if (IS_ERR_VALUE(ret)) return ret; So, gpmc_cs_set_timings() thinks any negative return value is an error, but where we check that in higher levels, only a limited range are errors... There is only _one_ use of IS_ERR_VALUE() in arch/arm which is really appropriate, and that is in arch/arm/include/asm/syscall.h: static inline long syscall_get_error(struct task_struct *task, struct pt_regs *regs) { unsigned long error = regs->ARM_r0; return IS_ERR_VALUE(error) ? error : 0; } because this function really does have to differentiate between error return values and addresses which look like negative numbers (eg, from mmap()). So, here's a patch to remove them from OMAP, except for the above. Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2013-04-09ARM: OMAP: Force dmtimer restore if context loss is not detectableJon Hunter
When booting with device-tree the function pointer for detecting context loss is not populated. Ideally, the pm_runtime framework should be enhanced to allow a means for reporting context/state loss and we could avoid populating such function pointers altogether. In the interim until a generic non-device specific solution is in place, force a restore of the dmtimer when enabling the timer.

2013-04-09ARM: OMAP: Simplify dmtimer context-loss handlingNeilBrown
The context loss handling in dmtimer appears to assume that omap_dm_timer_set_load_start() or omap_dm_timer_start() and omap_dm_timer_stop() bracket all interactions. Only the first two restore the context and the last updates the context loss counter. However omap_dm_timer_set_load() or omap_dm_timer_set_match() can reasonably be called outside this bracketing, and the fact that they call omap_dm_timer_enable() / omap_dm_timer_disable() suggest that is expected. So if, after a transition into and out of off-mode which would cause the dm timer to loose all state, omap_dm_timer_set_match() is called before omap_dm_timer_start(), the value read from OMAP_TIMER_CTRL_REG will be 'wrong' and this wrong value will be stored context.tclr so a subsequent omap_dm_timer_start() can fail (As the control register is wrong). Simplify this be doing the restore-from-context in omap_dm_timer_enable() so that whenever the timer is enabled, the context is correct. Also update the ctx_loss_count at the same time as we notice it is wrong - these is no value in delaying this until the omap_dm_timer_disable() as it cannot change while the timer is enabled.

2013-02-01ARM: OMAP2+: Get rid of custom OMAP_32K_TIMER_HZSantosh Shilimkar
The timekeeping doesn't depend on HZ value in presence of fine grained clocksource and hence there should not be any time drift because of HZ value which was chosen to be divisor of 32768. OMAP has been using HZ = 128 value to avoid any time drift issues because of 32768 HZ clock. But with various measurements performed with HZ = 100, no time drift is observed and it also proves the point about HZ not having impact on time keeping on OMAP.

2013-01-11ARM: OMAP2+: Disable code that currently does not work with multiplaformTony Lindgren
We still need to fix up few places for multiplatform support, but that can proceed separately. Fix the issue by making the problem drivers depends !ARCH_MULTIPLATFORM for now. The remaining pieces that are not multiplatform compatible for omap2+ SoCs are: 1. Some drivers are using custom omap_dm_timer calls There are two drivers that are directly usign omap hardware timers for PWM and DSP clocking: drivers/media/rc/ir-rx51.c and drivers/staging/tidspbridge/core/dsp-clock.c. These can be fixed for multiplatform by allowing a minimal set of hardware timers to be accessed, and for some functionality by using the hrtimer framework. 2. Hardware OMAP4_ERRATA_I688 needs to be fixed up This can't be enabled for multiplatform configurations in it's current form. It may be possible to fix it up to do instruction replacement early on during init. Luckily it looks like this errata does not seem to get hit with mainline kernel code alone at least currently. 3. Legacy header needed for omap-sham.c Looks like it still needs mach/irqs.h for omap1 that does not exist for multiplatform systems. Just ifdef it for now. 4. Mailbox is waiting to get moved to drivers Disable it for now to avoid adding a dependency to the mailbox patches.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-12-06mmc: omap_hsmmc: Enable HSPE bit for high speed cardsHebbar, Gururaja
HSMMC IP on AM33xx need a special setting to handle High-speed cards. Other platforms like TI81xx, OMAP4 may need this as-well. This depends on the HSMMC IP timing closure done for the high speed cards. From AM335x TRM (SPRUH73F - 18.3.12 Output Signals Generation): The MMC/SD/SDIO output signals can be driven on either falling edge or rising edge depending on the SD_HCTL[2] HSPE bit. This feature allows to reach better timing performance, and thus to increase data transfer frequency. There are few pre-requisites for enabling the HSPE bit - Controller should support High-Speed-Enable Bit and - Controller should not be using DDR Mode and - Controller should advertise that it supports High Speed in capabilities register and - MMC/SD clock coming out of controller > 25MHz Signed-off-by: Hebbar, Gururaja <gururaja.hebbar@ti.com> Signed-off-by: Venkatraman S <svenkatr@ti.com> Signed-off-by: Chris Ball <cjb@laptop.org>

So omap-for-v3.8/cleanup-headers-iommu should be added as one of the depends branches for arm-soc. * tag 'omap-for-v3.8/cleanup-headers-iommu-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: Move iommu/iovmm headers to platform_data ARM: OMAP2+: Make some definitions local ARM: OMAP2+: Move iommu2 to drivers/iommu/omap-iommu2.c ARM: OMAP2+: Move plat/iovmm.h to include/linux/omap-iommu.h ARM: OMAP2+: Move iopgtable header to drivers/iommu/ ARM: OMAP: Merge iommu2.h into iommu.h Conflicts due to surrounding changes in: arch/arm/mach-omap2/omap_hwmod_44xx_data.c drivers/media/platform/omap3isp/ispvideo.c Signed-off-by: Olof Johansson <olof@lixom.net>
