| | * | | | | | | ARM: OMAP: PRCM: add support for chain interrupt handlerTero Kristo2011-12-16

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.

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. The pending PRM IRQ functions are based on code originally written by Tero Kristo <t-kristo@ti.com>. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Tero Kristo <t-kristo@ti.com>

| * | | | | | | ARM: OMAP2+: hwmod: Add a new flag to handle hwmods left enabled at initRajendra Nayak2011-12-16

Once a real user of the device (a driver) tries to enable it at a later point, the hwmod framework throws a WARN() about the device being already in enabled state. Fix this by introducing a new internal flag '_HWMOD_SKIP_ENABLE' to identify such devices/hwmods. When the device/hwmod is requested to be enabled (the first time) by its driver/user, nothing except the mux-enable is needed. The mux data is board specific and is unavailable during initial enable() of the device, done by the framework as part of setup(). A good example of a such a device is an UART used as debug console. The UART module needs to be kept enabled through the boot, until the UART driver takes control of it, for debug prints to appear on the console.

Since these timers are not wakeup capable, we need the wakeup capable global timer to program the wakeup time depending on the next timer expiry. It can be handled by registering a global wakeup capable timer along with local timers marked with (mis)feature flag CLOCK_EVT_FEAT_C3STOP. Then notify the clock events layer from idle code using CLOCK_EVT_NOTIFY_BROADCAST_ENTER/EXIT). ARM local timers are already marked with C3STOP feature. Add the notifiers to OMAP4 CPU idle code for the broadcast entry and exit.

CPU1 is left with defualt idle and the low power state for it is managed via cpu-hotplug. This patch adds MPUSS low power states in cpuidle. C1 - CPU0 ON + CPU1 ON + MPU ON C2 - CPU0 OFF + CPU1 OFF + MPU CSWR C3 - CPU0 OFF + CPU1 OFF + MPU OSWR OMAP4460 onwards, MPUSS power domain doesn't support OFF state any more anymore just like CORE power domain. The deepest state supported is OSWr. Ofcourse when MPUSS and CORE PD transitions to OSWR along with device off mode, even the memory contemts are lost which is as good as the PD off state. On OMAP4 because of hardware constraints, no low power states are targeted when both CPUs are online and in SMP mode. The low power states are attempted only when secondary CPU gets offline to OFF through hotplug infrastructure.

| * | | | | | | ARM: OMAP4: Fix errata i688 with MPU interconnect barriers.Santosh Shilimkar2011-12-08

Patch 'OMAP4: PM: Add CPUX OFF mode support' added CPU PM support but OMAP errata i688 (Async Bridge Corruption) needs to be taken care to avoid issues like system freeze, CPU deadlocks, random crashes with register accesses, synchronisation loss on initiators operating on both interconnect port simultaneously. As per the errata, if a data is stalled inside asynchronous bridge because of back pressure, it may be accepted multiple times, creating pointer misalignment that will corrupt next transfers on that data path until next reset of the system (No recovery procedure once the issue is hit, the path remains consistently broken). Async bridge can be found on path between MPU to EMIF and MPU to L3 interconnect. This situation can happen only when the idle is initiated by a Master Request Disconnection (which is trigged by software when executing WFI on CPU). The work-around for this errata needs all the initiators connected through async bridge must ensure that data path is properly drained before issuing WFI. This condition will be met if one Strongly ordered access is performed to the target right before executing the WFI. In MPU case, L3 T2ASYNC FIFO and DDR T2ASYNC FIFO needs to be drained. IO barrier ensure that there is no synchronisation loss on initiators operating on both interconnect port simultaneously. Thanks to Russell for a tip to conver assembly function to C fuction there by reducing 40 odd lines of code from the patch.

The MPUSS OSWR configuration is as below. - CPUx L1 and logic lost, MPUSS logic lost, L2 memory is retained OMAP4460 onwards, MPUSS power domain doesn't support OFF state any more anymore just like CORE power domain. The deepest state supported is OSWR. On OMAP4430 secure devices too, MPUSS off mode can't be used because of a bug which alters Ducati and Tesla states. Hence MPUSS off mode as an independent state isn't supported on OMAP44XX devices. Ofcourse when MPUSS power domain transitions to OSWR along with device off mode, it eventually hits off state since memory contents are lost. Hence the MPUSS off mode independent state is not attempted without device off mode. All the necessary infrastructure code for MPUSS off mode is in place as part of this series.

The WakeupGen unit is responsible for generating the wakeup event from the incoming interrupts and enable bits. It is implemented in the MPU always ON power domain. During normal operation, WakeupGen delivers the external interrupts directly to the GIC. WakeupGen specification has one restriction as per Veyron version 1.6. It is SW responsibility to program interrupt enabling/disabling coherently in the GIC and in the WakeupGen enable registers. That is, a given interrupt for a given CPU is either enable at both GIC and WakeupGen, or disable at both, but no mix. That's the reason the WakeupGen is implemented as an extension of GIC.

The configuration of the clock activity bit field (per TRM) is as follows: 0x0: Both clocks can be cut off 0x1: Only OCP clock must be kept active; system clock can be cut off 0x3: Both clocks must be kept active 0x2: Only system clock must be kept active; OCP clock can be cut off The patch makes 0x2(CLOCKACT_TEST_ICLK) the default for OMAP3 and OMAP4.
