2011-12-16ARM: OMAP4: PRM: use PRCM interrupt handlerTero Kristo
Use the new PRCM interrupt handler code on OMAP4 systems. The OMAP code will need to be converted to use sparse IRQs for this to work. Until that time, the following message will appear on boot: PRCM: failed to allocate irq descs: -12 Signed-off-by: Tero Kristo <t-kristo@ti.com> Tested-by: Kevin Hilman <khilman@ti.com> Reviewed-by: Kevin Hilman <khilman@ti.com> [paul@pwsan.com: split this from a previous patch to this patch; call omap4xxx_prcm_init() during init; write trivial commit log] Signed-off-by: Paul Walmsley <paul@pwsan.com>
2011-12-16ARM: OMAP3: pm: use prcm chain handlerTero Kristo
PM interrupt handling is now done through the PRCM chain handler. The interrupt handling logic is also split in two parts, to serve IO and WKUP events separately. This allows us to handle IO chain events in a clean way. Core event code is also changed in accordance to this, as PRCM interrupt handling is done by independent handlers, and the core handler should not clear the IO events anymore.

2011-12-16ARM: OMAP: hwmod: add support for selecting mpu_irq for each wakeup padTero Kristo
By default all registered pads will trigger mpu_irqs[0]. Now there is an API for selecting used mpu_irq on pad basis, which can be used to trigger different irq handlers for different pads in the same hwmod. Each pad that requires its interrupt to be re-routed this way must have a separate call to omap_hwmod_pad_route_irq(hwmod, pad, irq).

2011-12-16ARM: OMAP2+: mux: add support for PAD wakeup interruptsTero Kristo
OMAP mux now parses active wakeup events from pad registers and calls corresponding hwmod ISRs once a wakeup is detected. This is accomplished by registering an interrupt handler for PRCM IO event, which is raised every time the HW detects wakeups. [paul@pwsan.com: This patch is a merge of Govindraj R's "ARM: OMAP2+: hwmod: Add API to check IO PAD wakeup status" patch, Tero Kristo's "ARM: OMAP2+: mux: add support for PAD wakeup interrupts" patch, and part of Tero's "ARM: OMAP: mux: add support for selecting mpu_irq for each wakeup pad" patch.] Signed-off-by: Tero Kristo <t-kristo@ti.com> Cc: Govindraj.R <govindraj.raja@ti.com> Tested-by: Kevin Hilman <khilman@ti.com> Reviewed-by: Kevin Hilman <khilman@ti.com> Acked-by: Tony Lindgren <tony@atomide.com> [paul@pwsan.com: reduced indentation level; renamed omap_hwmod function; improved function documentation; modified to iterate only through dynamic pads; modified to skip pads where idle mode doesn't enable wakeups; split patches] Signed-off-by: Paul Walmsley <paul@pwsan.com>
2011-12-16ARM: OMAP: PRCM: add suspend prepare / finish supportTero Kristo
PRCM chain handler needs to disable forwarding of interrupts during suspend, because runtime PM is disabled and most of the drivers are potentially not able to handle interrupts coming at this time. This patch masks all the PRCM interrupt events if a PRCM interrupt occurs during suspend, but does not ack them. Once suspend finish is called, all the masked events will be re-enabled, which causes immediate PRCM interrupt and handles the postponed event. The suspend prepare and complete callbacks will be called from pm34xx.c / pm44xx.c files in the following patches. The functions defined in this patch should eventually be moved to suspend->prepare and suspend->finish driver hooks, once the PRCM chain handler will be made as its own driver.

2011-12-16ARM: OMAP: PRCM: add support for chain interrupt handlerTero Kristo
Introduce a chained interrupt handler mechanism for the PRCM interrupt, so that individual PRCM event can cleanly be handled by handlers in separate drivers. We do this by introducing PRCM event names, which are then matched to the particular PRCM interrupt bit depending on the specific OMAP SoC being used. PRCM interrupts have two priority levels, high or normal. High priority is needed for IO event handling, so that we can be sure that IO events are processed before other events. This reduces latency for IO event customers and also prevents incorrect ack sequence on OMAP3.

2011-12-16ARM: OMAP3/4: PRM: add functions to read pending IRQs, PRM barrierPaul Walmsley
Add PRM functions to test for pending PRM IRQs. This will be used in a subsequent patch to implement the PRM interrupt handler on the MPU. Add PRM functions to ensure that all outstanding writes from the MPU to the PRM IP block have completed before continuing execution. This will be used in a subsequent patch to ensure that all PRM interrupt status bits are cleared in the hardware before exiting the ISR. Normally we would not expose such a low-level function to other code. But the current implementation of the PRM interrupt code, which uses the generic IRQ chip code, doesn't give us a choice.

Add API to enable IO pad wakeup capability based on mux pad and wake_up enable flag available from hwmod_mux initialization. Use the wakeup_enable flag and enable wakeup capability for the given pads. Wakeup capability will be enabled/disabled during hwmod idle transition based on whether wakeup_flag is set or cleared.

2011-12-16ARM: OMAP2+: mux: add wakeup-capable hwmod mux entries to dynamic listPaul Walmsley
omap_hwmod_mux() currently only iterates through the dynamic pad list. This list currently only consists of pads with the OMAP_DEVICE_MUX_REMUX flag set. Subsequent patches in this series will cause hwmod mux entries with the OMAP_DEVICE_MUX_WAKEUP flag set to be changed dynamically, to control hwmod I/O ring wakeup. For this to work correctly, hwmod mux entries with the OMAP_DEVICE_MUX_WAKEUP flag set must also be added to the dynamic pad list. So this patch modifies omap_hwmod_mux_init() to do so.

2011-11-30ARM: 7181/1: Restrict kprobes probing SWP instructions to ARMv5 and belowJon Medhurst (Tixy)
The SWP instruction is deprecated on ARMv6 and with ARMv7 it will be UNDEFINED when CONFIG_SWP_EMULATE is selected. In this case, probing a SWP instruction will cause an oops when the kprobes emulation code executes an undefined instruction. As the SWP instruction should be rare or non-existent in kernels for ARMv6 and later, we can simply avoid these problems by not allowing probing of these.

2011-11-30ARM: 7180/1: Change kprobes testcase with unpredictable STRD instructionJon Medhurst (Tixy)
There is a kprobes testcase for the instruction "strd r2, [r3], r4". This has unpredictable behaviour as it uses r3 for register writeback addressing and also stores it to memory. On a cortex A9, this testcase would fail because the instruction writes the updated value of r3 to memory, whereas the kprobes emulation code writes the original value. Fix this by changing testcase to used r5 instead of r3.

When compiling kprobes-test-thumb.c an error like below may occur: /tmp/ccKcuJcG.s:19179: Error: offset out of range This is caused by the compiler underestimating the size of the inline assembler instructions containing ".space 0x1000" and failing to spill the literal pool in time to prevent the generation of PC relative load instruction with invalid offsets. The fix implemented by this patch is to replace a single large .space directive by a number of 4 byte .space's.

2011-11-23ARM: OMAP2: select ARM_AMBA if OMAP3_EMU is definedMing Lei
This patch selects ARM_AMBA if OMAP3_EMU is defined because OC_ETM depends on ARM_AMBA, so fix the link failure[1].

Fix a bug which has been on this driver since it was added by the original commit 984aa6db which would never clear IRQSTATUS bits. Signed-off-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Kevin Hilman <khilman@ti.com> Cc: stable@vger.kernel.org Signed-off-by: Tony Lindgren <tony@atomide.com>
2011-11-23ARM: OMAP: PM: only register TWL with voltage layer when device is presentKevin Hilman
Current code registers voltage layer details for TWL PMIC even when a TWL has not been registered. Fix this to only register the TWL with voltage layer when the TWL PMIC is initialized by board-level code.

2011-11-23ARM: OMAP: hwmod: Fix the addr space, irq, dma count APIssricharan
The address spaces, irqs and dma reqs count APIs return the number of corresponding entries in a hwmod including a additional null value or a -1 terminator in the structure introduced recently. More information here: - 212738a4: omap_hwmod: use a terminator record with omap_hwmod_mpu_irqs arrays - 78183f3f: omap_hwmod: use a null structure record to terminate omap_hwmod_addr_space arrays - bc614958: omap_hwmod: use a terminator record with omap_hwmod_dma_info arrays The issue with irqs and dma info was originally reported by Benoit Cousson. The devices which have multiple hwmods and use device_build_ss are broken with this, as their resources are populated with a extra null value, subsequently the probe fails. So fix the API not to include the array terminator in the count.
