| | * ARM: OMAP2+: PM: share some suspend-related functions across OMAP2, 3, 4Paul Walmsley2012-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The platform_suspend_ops can be shared across OMAP2, 3, and 4, along with all of the functions referenced in that structure. This patch shares them. It also removes the suspend_state file-scoped variable in the OMAP2 and 3 PM code; it does not appear to be actually needed by anything.

| | * ARM: OMAP2+: omap_device: call all suspend, resume callbacks when ↵Paul Walmsley2012-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP_DEVICE_NO_IDLE_ON_SUSPEND is set During system suspend, when OMAP_DEVICE_NO_IDLE_ON_SUSPEND is set on an omap_device, call the corresponding driver's ->suspend() and ->suspend_noirq() callbacks (if present). Similarly, during resume, the driver's ->resume() and ->resume_noirq() callbacks must both be called, if present. (The previous code only called ->suspend_noirq() and ->resume_noirq().) If all of these callbacks aren't called, some important driver suspend/resume code may not get executed. In current mainline, the bug fixed by this patch is only a problem under the following conditions: - the kernel is running on an OMAP4 - an OMAP UART is used as a console - the kernel command line parameter 'no_console_suspend' is specified - and the system enters suspend ("echo mem > /sys/power/state"). Under this combined circumstance, the system cannot be awakened via the serial port after commit be4b0281956c5cae4f63f31f11d07625a6988766c ("tty: serial: OMAP: block idle while the UART is transferring data in PIO mode"). This is because the OMAP UART driver's ->suspend() callback is never called. The ->suspend() callback would have called uart_suspend_port() which in turn would call enable_irq_wake(). Since enable_irq_wake() isn't called for the UART's IRQ, check_wakeup_irqs() would mask off the UART IRQ in the GIC. On v3.3 kernels prior to the above commit, serial resume from suspend presumably occurred via the PRCM interrupt. The UART was in smart-idle mode, so it was able to send a PRCM wakeup which in turn would be converted into a PRCM interrupt to the GIC, waking up the kernel. But after the above commit, when the system is suspended in the middle of a UART transmit, the UART IP block would be in no-idle mode. In no-idle mode, the UART won't generate wakeups to the PRCM when incoming characters are received; only GIC interrupts. But since the UART driver's ->suspend() callback is never called, uart_suspend_port() and enable_irq_wake() is never called; so the UART interrupt is masked by check_wakeup_irqs() and the UART can't wake up the MPU. The remaining mechanism that could have awakened the system would have been I/O chain wakeups. These wouldn't be active because the console UART's clocks are never disabled when no_console_suspend is used, preventing the full chip from idling. Also, current mainline doesn't yet support full chip idle states for OMAP4, so I/O chain wakeups are not enabled. This patch is the result of a collaboration. John Stultz <johnstul@us.ibm.com> and Andy Green <andy.green@linaro.org> reported the serial wakeup problem that led to the discovery of this problem. Kevin Hilman <khilman@ti.com> narrowed the problem down to the use of no_console_suspend.

| | * ARM: OMAP: omap_device: remove omap_device_parentKevin Hilman2012-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently all omap_devices are forced to have the dummy device 'omap_device_parent' as a parent. This was used to distinguish omap_devices from "normal" platform_devices in the OMAP PM core code. Now that we implement the PM core using PM domains, this is no longer needed, and is removed. This also frees up omap_devices to have a more complex parent/child relationships that model actual device relationships. The only in-tree user of omap_device_parent was the OMAP PM layer to handle lost-context count for omap_devices. That is now converted to use the presence of the omap_device_pm_domain instead.

Not needed unless LOWPOWERSTATECHANGE is used, because the state switch code is called by either clkdm_sleep() or clkdm_allow_idle(). - Add code to wait for the power state transition in the OMAP4+ low power state change. This is speculative, so I would particularly appreciate feedback on this part. - Remove a superfluous call to pwrdm_read_pwrst(). - Update variable names to be more meaningful (hopefully) and precise. - Fix an error path bug that would not place the clockdomain back into hardware-supervised idle or sleep mode if the power state could not be programmed. The documentation for this function still needs major improvements; that's left for a later patch.

N.B.: some of us have observed that accesses to the previous powerstate registers seem to be quite slow. Although the writes removed by this patch should be buffered by the write buffer, there is a read to a PRM register immediately afterwards. That will block the OMAP3 MPU until all of those writes complete. So this patch should result in a minor performance improvement during idle entry.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that omap hsmmc init is split into two functions, it's safe to mark omap_hsmmc_init and omap_mux related functions to __init. This basically reverts the following fixes for the case where TWL was compiled as a module: a98f77b (ARM: omap: fix section mismatch warning for sdp3430_twl_gpio_setup()) 8930b4e (ARM: omap: fix section mismatch warnings in mux.c caused by hsmmc.c) Additionally it fixes up the remaining section warnings for all callers of omap_mux functions.

| * | ARM: OMAP2+: Split omap2_hsmmc_init() to properly support I2C GPIO pinsTony Lindgren2012-02-20

If a board is using GPIO pins or regulators configured by an external chip, such as TWL PMIC on I2C bus, the board must mark those MMC controllers as deferred. Additionally both omap_hsmmc_init() and omap_hsmmc_late_init() must be called by the board. For MMC controllers using internal GPIO pins for card detect and regulators the slots don't need to be marked deferred. In this case calling omap_hsmmc_init() is sufficient. Only mark the MMC slots using gpio_cd or gpio_wd as deferred as noted by Igor Grinberg <grinberg@compulab.co.il>. Note that this patch does not change the behaviour for board-4430sdp.c board-omap4panda.c. These boards wrongly rely on the omap_hsmmc.c init function callback to configure the PMIC GPIO interrupt lines on external chip. If the PMIC interrupt lines are not configured during init, they will fail.

This approach allows users, which need to manipulate an archdata member of a device before it is registered, to do so. This is also useful for users who have their devices created very early so they can be used at ->reserve() time to reserve CMA memory. The immediate use case for this is to set the private iommu archdata member, which binds a device to its associated iommu controller. This way, generic code will be able to attach omap devices to their iommus, without calling any omap-specific API. With this in hand, we can further clean the existing mainline OMAP iommu driver and its mainline users, and focus on generic IOMMU approaches for future users (rpmsg/remoteproc and the upcoming generic DMA API). This patch is still considered an interim solution until DT fully materializes for omap; at that point, this functionality will be removed as DT will take care of creating the devices and configuring them correctly. Tested on OMAP4 with a generic rpmsg/remoteproc that doesn't use any omap-specific IOMMU API anymore.

If twl4030_gpio is compiled as a module, bad things can happen because the callback function starts calling functions that are supposed to be marked __init: Kernel panic - not syncing: Attempted to kill the idle task! twl4030_gpio twl4030_gpio: can't dispatch IRQs from modules gpiochip_add: registered GPIOs 192 to 209 on device: twl4030 Unable to handle kernel paging request at virtual address b82a4c74 ... Additionally if this does not fail, warnings are produced about trying to register the MMC multiple times. Fix this by removing __init from omap_mux_get_by_name, and add checks if omap2_hsmmc_init() is getting called more than once. Note that this will get fixed properly later on by splitting omap2_hsmmc_init into two functions.

There was also no activity in this regard through the last kernel releases, so it seems this situation will not change in the future. Therefore this patch removes this seemingly dead code.
