2010-07-05omap: Move omap2 FS USB platform init code into mach-omap2/usb-fs.cTony Lindgren
Move omap2 FS USB platform init code into mach-omap2/usb-fs.c. This will allow further work later on to use omap hwmod for initializing the device. Cc: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Tony Lindgren <tony@atomide.com>

2010-06-29omap iommu: move iommu_disable at fault to the above layerHiroshi DOYU
The function prefix "omap2_iommu_" indicates that the prefixed function belongs to "omap2_iommu_ops" to provide iommu basic functionalities for the above layers. It's better to avoid the prefixed function called in the same prefixed ones internally, like nested here. Now "iommu_disable" is called just after fault_isr() in the above layer. This is a little bit more sensible to keep the consistency of module layers. Signed-off-by: Hiroshi DOYU <Hiroshi.DOYU@nokia.com>
2010-06-29omap iommu: add functionality to get TLB miss interruptKanigeri, Hari
In order to enable TLB miss interrupt, the TWL should be disabled. This patch provides the functionality to get the MMU fault interrupt for a TLB miss in the cases where the users are working with the locked TLB entries and with TWL disabled. New interface is added to select twl and to enable TLB miss interrupt.

2010-06-10omap: GPIO: fix auto-disable of debounce clockKevin Hilman
The addition of the new debounce code (commit 168ef3d9a56bd8bffe0ef4189c450888b4aefefe) broke the auto-disable of debounce clocks on idle by forgetting to update the debounce clock enable mask.

2010-06-10omap: DMTIMER: Ack pending interrupt always when stopping a timerTero Kristo
The kernel timer queue is being run currently from a GP timer running in a one shot mode, which works in a way that when it expires, it will also stop. Usually during this situation, the interrupt handler will ack the interrupt, load a new value to the timer and start it again. During suspend, the situation is slightly different, as we disable interrupts just before timekeeping is suspended, which leaves a small window where the timer can expire before it is stopped, and will leave the interrupt flag pending. This pending interrupt will prevent ARM sleep entry, thus now we ack it always when we are attempting to stop a timer.

There is no common base address anymore for all the CM registers. The easiest way to handle that on OMAP4 is to provide the absolute address of the XXX_CLKCTRL register per hwmod.

2010-05-20OMAP2+ clock: remove DEFAULT_RATE clksel_rate flagPaul Walmsley
The DEFAULT_RATE clksel_rate flag is essentially useless. It was set on some of the lowest divisors, which, when switching to a much higher-rate parent, could have potentially resulted in rates that exceeded the hardware specifications for downstream clocks in the window between the clk_set_parent(), and a subsequent clk_set_rate(). It seems much safer to just remove the flag and always use the highest available divisor (resulting in the lowest possible rate) after the switch, and this patch does so. Ideally, it would be best to first attempt to switch to a divisor that matches the clock's rate with the previous parent, if at all possible. But that is a project for some other day or some other person. The parent changing code is rarely used. Signed-off-by: Paul Walmsley <paul@pwsan.com>

2010-05-19i2c-omap: add mpu wake up latency constraint in i2cKalle Jokiniemi
While waiting for completion of the i2c transfer, the MPU could hit OFF mode and cause several msecs of delay that made i2c transfers fail more often. The extra delays and subsequent re-trys cause i2c clocks to be active more often. This has also an negative effect on power consumption. Created a mechanism for passing and using the constraint setting function in driver code. The used mpu wake up latency constraints are now set individually per bus, and they are calculated based on clock rate and fifo size. Thanks to Jarkko Nikula, Moiz Sonasath, Paul Walmsley, and Nishanth Menon for tuning out the details of this patch. Updates by Kevin as requested by Tony: - Remove omap_set_i2c_constraint_func() in favor of conditionally adding the flag in omap_i2c_add_bus() in order to keep all the OMAP conditional checking in a single location. - Update set_mpu_wkup_lat prototypes to match OMAP PM layer so OMAP PM function can be used directly in pdata.
