* omap3: PM: enable UART3 module wakeupsKevin Hilman2009-10-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | UART3 is in the PER powerdomain. If PER goes idle/inactive independently of CORE, for UART3 to wakeup it must have its wakeup enable bits setup in PM_WKEN_PER. This patch enables these bits. The reason it works when PER and CORE work together is because when CORE goes inactive/retention, the IOPAD wakeups are enabled and trigger UART3 wakeup. Without this patch, when the UART inactivity timer fires for UART3, its clocks are disabled and it's unable to wakeup so will be unusable until PER is awoken by another source. Another way of testing is by keeping CORE on during suspend but allowing PER to hit retention # echo 3 > /debug/pm_debug/core_pwrdm/suspend then enter suspend # echo mem > /sys/power/state Without this patch, UART3 will be unable to wakeup the system.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a possible race condition in clockdomain code handling hw supported idle transitions. When multiple autodeps dependencies are being added or removed, a transition of still remaining dependent powerdomain can result in false readings of the state counter. This is especially fatal for off mode state counter, as it could result in a driver not noticing a context loss. Fixed by disabling hw supported state transitions when autodeps are being changed.

| * | OMAP3: PM: Enable GPIO module-level wakeupsKevin Hilman2009-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, only GPIOs in the wakeup domain (GPIOs in bank 0) are enabled as wakups. This patch also enables GPIOs in the PER powerdomain (banks 2-6) to be used as possible wakeup sources. In addition, this patch ensures that all GPIO wakeups can wakeup the MPU using the PM_MPUGRPSEL_<pwrdm> registers. NOTE: this doesn't enable the individual GPIOs as wakeups, this simply enables the per-bank wakeups at the powerdomain level. This problem was discovered by Mike Chan when preventing the CORE powerdomain from going into retention/off. When CORE was allowed to hit retention, GPIO wakeups via IO pad were working fine, but when CORE remained on, GPIO module-level wakeups were not working properly. To test, prevent CORE from going inactive/retention/off, thus preventing the IO chain from being armed: # echo 3 > /debug/pm_debug/core_pwrdm/suspend This ensures that GPIO wakeups happen via module-level wakeups and not via IO pad. Tested on 3430SDP using the touchscreen GPIO (gpio 2, in WKUP) Tested on Zoom2 using the QUART interrup GPIO (gpio 102, in PER) Also, c.f.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clearing wakeup sources is now only done when the PRM indicates a wakeup source interrupt. Since we don't handle any other types of PRCM interrupts right now, warn if we get any other type of PRCM interrupt. Either code needs to be added to the PRCM interrupt handler to react to these, or these other interrupts should be masked off at init. Updated after Jon Hunter's PRCM IRQ rework by Kevin Hilman.

Otherwise the MPU PRCM interrupt handler could wind up clearing wakeup events meant for the IVA PRCM interrupt handler.

These are: 1). Waiting for PRM_IRQSTATUS_MPU register to clear. Bit 0 of the PRM_IRQSTATUS_MPU register indicates that a wake-up event is pending for the MPU. This bit can only be cleared if the all the wake-up events latched in the various PM_WKST_x registers have been cleared. If a wake-up event occurred during the processing of the prcm interrupt handler, after the corresponding PM_WKST_x register was checked but before the PRM_IRQSTATUS_MPU was cleared, then the CPU would be stuck forever waiting for bit 0 in PRM_IRQSTATUS_MPU to be cleared. 2). Waiting for the PM_WKST_x register to clear. Some power domains have more than one wake-up source. The PM_WKST_x registers indicate the source of a wake-up event and need to be cleared after a wake-up event occurs. When the PM_WKST_x registers are read and before they are cleared, it is possible that another wake-up event could occur causing another bit to be set in one of the PM_WKST_x registers. If this did occur after reading a PM_WKST_x register then the CPU would miss this event and get stuck forever in a loop waiting for that PM_WKST_x register to clear. This patch address the above race conditions that would result in a hang.

This change makes the driver useful for other architectures as well. Needed for the SuperH kfr2r09 board. Apart from the obvious Kconfig bits, the most important change is the move away from ARM specific includes and platform data. Together with this change the only in-tree board code gets an update, and the driver name is also changed gracefully break potential out of tree drivers. The driver is also updated to allow NULL as platform data together with a few changes to make use of resource_size() and dev_name().
