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 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_ 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.

It also allows the platform to specify the udelay and timeout. 2) Program the gpio configuration register to enable/disable the open drain drivers. Note that this really only works if the sda and scl pins are set to EP93XX_GPIO_LINE_EEDAT and EP93XX_GPIO_LINE_EECLK. 3) Update the edb93xx.c platform init to use the new support.

Many of these internal clocks can be stopped to save power. This introduces a "parent" hierarchy for the clocks so that the users count can be correctly tracked for power management. The "parent" for the video clock can either be one of the PLL outputs or the external oscillator. In order to correctly track the "parent" for the video clock calc_clk_div() needed to be modified. It now returns an error code if the desired rate cannot be generated.

The correct behavior would be to force the flush based on dcache_dirty bit only. One of the cases where present logic would be a problem is when a RAM based block device[1] is used as a swap disk. In this case, we would have in-memory data corruption as shown in steps below: do_swap_page() { - Allocate a new page (if not already in swap cache) - Issue read from swap disk - Block driver issues flush_dcache_page() - flush_dcache_page() simply sets PG_dcache_dirty bit and does not actually issue a flush since this page has no user space mapping yet. - Now, if swap disk is almost full, this newly read page is removed from swap cache and corrsponding swap slot is freed. - Map this page anonymously in user space. - update_mmu_cache() - Since this page does not have kernel mapping (its not in page/swap cache and is mapped anonymously), it does not issue dcache flush even if dcache_dirty bit is set by flush_dcache_page() above. } Same problem exists on mips too.

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.

This works for mach-omap2, but causes issues on mach-omap1 for some boards as the mach-omap1 serial.c was muxing pins based on the enabled_uart flag for 15xx. Fix this by muxing pins in board-*.c files for the 15xx boards for the uart ports that had enabled_uart flag set before the commit above. Tested on Amsdtrad Delta only. Note that in the future we should add support for powering down the uarts with a timer like mach-omap2/serial.c does. Otherwise the enabled uarts will be blocking retention-while-idle.

For several months it is no longer included, breaking support for McBSP1 based audio on Amstrad Delta, for example. This patch, derived from the old dspgateway code, corrects the problem for the board by simply taking the DSP out of reset state, I guess. That way, things should not break when a new dsp code is added to the tree, and the change can be reverted then. If there are any reports on McBSP1 or other DSP public peripherals not working for other OMAP1 machines (I've not heard of any for now), I can prepare a more general patch providing an extra include file with a helper function defined.

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.

During boot, we encounter a situation when we're updating the kernel's page tables which can lead to dirty cache lines existing in the cache which are subsequently missed. This causes stack corruption, and therefore a crash. Therefore, ensure that the shared and cacheability settings matches the configuration that will be used later; this together with the restriction in early_cachepolicy() ensures that we won't create a mismatch during boot.

Fix this by setting the base address of the PCIe I/O space struct resource to KIRKWOOD_PCIE_IO_BUS_BASE instead of the incorrect KIRKWOOD_PCIE_IO_PHYS_BASE, and fix up __io() to expect addresses offsetted by the former instead of the latter. (The suggested fix of directing I/O port accesses from the host to bus addresses f20xxxxx instead has the problem that assigning full 32bit I/O port bus addresses (f20xxxxx) doesn't work on all PCI devices, as not all PCI devices implement full 32 bit BAR registers for I/O ports. We should really try to allocate I/O port bus addresses that fit in 16 bits.)

Looking closer at this I have found that it had been broken almost 2 years ago with commit 2418996e3b100114edb2ae110d5d4acb928909d2, PM fixes for OMAP1. The definite reason for broken omapfb/lcdc behavoiur in PM mode appeared to be ARM_IDLECT1:IDLIF_ARM (bit 6) put into idle regardless of LCD DMA possibly running. The bit were set based on return value of the omap_dma_running() function that did not check for dedicated LCD DMA channel status. The patch below fixes this. Note that the hardcoded register value will be fixed during the next merge cycle to use OMAP_LCDC_ defines. Currently the OMAP_LCDC_ defines are local to drivers/video/omap/lcdc.c, so let's not start moving those right now.
