2012-10-31ARM: OMAP2+: hwmod: add flag to prevent hwmod code from touching IP block ↵Paul Walmsley
during init Add HWMOD_EXT_OPT_MAIN_CLK flag to indicate that this IP block is dependent on an off-chip functional clock that is not guaranteed to be present during initialization. IP blocks marked with this flag are left in the INITIALIZED state during kernel init. This is a workaround for a hardware problem. It should be possible to guarantee that at least one clock source will be present and active for any IP block's main functional clock. This ensures that the hwmod code can enable and reset the IP block. Resetting the IP block during kernel init prevents any bogus bootloader, ROM code, or previous OS configuration from affecting the kernel. Hopefully a clock multiplexer can be added on future SoCs. N.B., at some point in the future, it should be possible to query the clock framework for this type of information. Then this flag should no longer be needed.

This reverts commit 957ee7270d632245b43f6feb0e70d9a5e9ea6cf6 (serial: omap: fix software flow control). As Russell has pointed out, that commit isn't fixing Software Flow Control at all, and it actually makes it even more broken.

2012-10-13ARM: config: sort select statements alphanumericallyRussell King
As suggested by Andrew Morton: This is a pet peeve of mine. Any time there's a long list of items (header file inclusions, kconfig entries, array initalisers, etc) and someone wants to add a new item, they *always* go and stick it at the end of the list. Guys, don't do this. Either put the new item into a randomly-chosen position or, probably better, alphanumerically sort the list. lets sort all our select statements alphanumerically. This commit was created by the following perl: while (<>) { while (/\\\s*$/) { $_ .= <>; } undef %selects if /^\s*config\s+/; if (/^\s+select\s+(\w+).*/) { if (defined($selects{$1})) { if ($selects{$1} eq $_) { print STDERR "Warning: removing duplicated $1 entry\n"; } else { print STDERR "Error: $1 differently selected\n". "\tOld: $selects{$1}\n". "\tNew: $_\n"; exit 1; } } $selects{$1} = $_; next; } if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or /^endif/ or /^endchoice/)) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } undef %selects; } print; } if (%selects) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } } It found two duplicates: Warning: removing duplicated S5P_SETUP_MIPIPHY entry Warning: removing duplicated HARDIRQS_SW_RESEND entry and they are identical duplicates, hence the shrinkage in the diffstat of two lines.

Pull i2c-embedded changes from Wolfram Sang: "The changes for i2c-embedded include: - massive rework of the omap driver - massive rework of the at91 driver. In fact, the old driver gets removed; I am okay with this approach since the old driver was depending on BROKEN and its limitations made it practically unusable, so people used bitbanging instead. But even if there are users, there is no platform_data or module parameter which would need to be converted. It is just another driver doing I2C transfers, just way better. Modifications of arch/arm/at91 related files have proper acks from the maintainer. - new driver for R-Car I2C - devicetree and generic_clock conversions and fixes - usual driver fixes and changes. The rework patches have come a long way and lots of people have been involved in creating/testing them. Most patches have been in linux-next at least since 3.6-rc5. A few have been added in the last week, I have to admit. An unexpected (but welcome :)) peak in private life is the cause for that. The "late" patches shouldn't cause any merge conflicts and I will have a special eye on them during the stabilization phase.

2012-10-06ARM: OMAP: convert I2C driver to PM QoS for MPU latency constraintsJean Pihet
Convert the driver from the outdated omap_pm_set_max_mpu_wakeup_lat API to the new PM QoS API. Since the constraint is on the MPU subsystem, use the PM_QOS_CPU_DMA_LATENCY class of PM QoS. The resulting MPU constraints are used by cpuidle to decide the next power state of the MPU subsystem. The I2C device latency timing is derived from the FIFO size and the clock speed and so is applicable to all OMAP SoCs.

Pull workqueue changes from Tejun Heo: "This is workqueue updates for v3.7-rc1. A lot of activities this round including considerable API and behavior cleanups. * delayed_work combines a timer and a work item. The handling of the timer part has always been a bit clunky leading to confusing cancelation API with weird corner-case behaviors. delayed_work is updated to use new IRQ safe timer and cancelation now works as expected. * Another deficiency of delayed_work was lack of the counterpart of mod_timer() which led to cancel+queue combinations or open-coded timer+work usages. mod_delayed_work[_on]() are added. These two delayed_work changes make delayed_work provide interface and behave like timer which is executed with process context. * A work item could be executed concurrently on multiple CPUs, which is rather unintuitive and made flush_work() behavior confusing and half-broken under certain circumstances. This problem doesn't exist for non-reentrant workqueues. While non-reentrancy check isn't free, the overhead is incurred only when a work item bounces across different CPUs and even in simulated pathological scenario the overhead isn't too high. All workqueues are made non-reentrant. This removes the distinction between flush_[delayed_]work() and flush_[delayed_]_work_sync(). The former is now as strong as the latter and the specified work item is guaranteed to have finished execution of any previous queueing on return. * In addition to the various bug fixes, Lai redid and simplified CPU hotplug handling significantly. * Joonsoo introduced system_highpri_wq and used it during CPU hotplug. There are two merge commits - one to pull in IRQ safe timer from tip/timers/core and the other to pull in CPU hotplug fixes from wq/for-3.6-fixes as Lai's hotplug restructuring depended on them." Fixed a number of trivial conflicts, but the more interesting conflicts were silent ones where the deprecated interfaces had been used by new code in the merge window, and thus didn't cause any real data conflicts.

Pull ARM soc-specific updates from Olof Johansson: "Most notable here is probably the addition of basic support for the BCM2835, an SoC used in some of the Roku 2 players as well as the much-hyped Raspberry Pi, cleaned up and contributed by Stephen Warren. It's still early days on mainline support, with just the basics working. But it has to start somewhere! Beyond that there's some conversions of clock infrastructure on tegra to common clock, misc updates for several other platforms, and OMAP now has its own bus (under drivers/bus) to manage its devices through. This branch adds two new directories outside of arch/arm: drivers/irqchip for new irq controllers, and drivers/bus for the above OMAP bus. It's expected that some of the other platforms will migrate parts of their platforms to those directories over time as well."

2012-09-23ARM: OMAP: Add a timer attribute for timers that can interrupt the DSPJon Hunter
Some instances of the DMTIMER peripheral on OMAP devices have the ability to interrupt the on-chip DSP in addition to the ARM CPU. Add a DMTIMER attribute to indicate which timers can interrupt the DSP. By using the omap_dm_timer_request_by_cap() API, driver will now be able to allocate a DMTIMER that can interrupt the DSP based upon this attribute and not require the driver to know which instance has this capability. DMTIMERs that have the ability to interrupt the DSP on OMAP devices are as follows ... - OMAP1 (OMAP5912/16xx/17xx) devices - All 8 DMTIMERs - OMAP2/3/4 devices - DMTIMERs 5-8 Please note that for OMAP3+, timer8 has the ability to interrupt the DSP and generate a PWM output.

2012-09-23ARM: OMAP4: hwmod data: add support for lostcontext_maskTero Kristo
Currently hwmod only provides the offset for the context lose register, and if we attempt to share the same register between two or more hwmods, the resulting context loss counts get wrong. Thus, we need a way to specify which bits are used for the context loss information for each. This is accomplished by adding a new field to the omap4 prcm struct, 'lostcontext_mask', which specifies a bit-mask to use for filtering the register. Mark the affected hwmods appropriately. 'l4_abe' hwmod uses the LOSTMEM_AESSMEM bit of RM_ABE_AESS_CONTEXT register, as l4_abe doesn't have its own dedicated register for this purpose. This register is shared with 'aess' hwmod, thus both hwmods must also specify which bits of the register are used for them. This patch only adds the hwmod data, but a future patch should add code support such that only the specified bits are read and cleared by the context lose counter update code. If a hwmod doesn't specify 'lostcontext_mask' (default behavior), the whole contents of the context register should be used without any filtering.
