The sh7372 A3SM hardware power domain contains the ARM Cortex-A8 CPU Core including L2 cache. This sleep mode can be seen as a one step deeper sleep mode from the already existing Core Standby mode. To wake up from A3SM sleep only a few wakeup sources are supported - so the regular INTC controller will not be able to help us unfortunately. The code in this patch will enter A3SM sleep via the regular Suspend-to-RAM interface in the case of only wakeups supported by A3SM are enabled. If unsupported wakeups are enabled then Core Standby will be used instead. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

| | * | | | | | PM / Domains: Preliminary support for devices with power.irq_safe setRafael J. Wysocki2011-08-25
| | | |/ / / / | | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The generic PM domains framework currently doesn't work with devices whose power.irq_safe flag is set, because runtime PM callbacks for such devices are run with interrupts disabled and the callbacks provided by the generic PM domains framework use domain mutexes and may sleep. However, such devices very well may belong to power domains on some systems, so the generic PM domains framework should take them into account. For this reason, modify the generic PM domains framework so that the domain .power_off() and .power_on() callbacks are never executed for a domain containing devices with power.irq_safe set, although the .stop_device() and .start_device() callbacks are still run for them. Additionally, introduce a flag allowing the creator of a struct generic_pm_domain object to indicate that its .stop_device() and .start_device() callbacks may be run in interrupt context (might_sleep_if() triggers if that flag is not set and one of those callbacks is run in interrupt context).

Move them to a separate header file. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

This is suboptimal and can be simplified by using power.sybsys_data to store device information used by the generic PM domains code. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

It also serves as an example of how to use the pinmux subsystem. This driver also houses the platform data for the only supported platform. This deletes the old U300 driver in arch/arm/mach-u300 and replace it with a driver using the new subsystem. The new driver is considerably fatter than the old one, but it also registers all 467 pins of the system and adds the power and EMIF pin groups and corresponding functions. The idea is to use this driver as a a reference for other implementation so it needs to be as complete and verbose as possible.

This doesn't need to be done in order to call calibrate_delay(). calibrate_delay() monitors jiffies, which are updated from the CPU which is waiting for the new CPU to set the online bit. So simply calibrate_delay() can be called on the new CPU just from the interrupt disabled region and move the local timer setup after stored the cpu data and before enabling interrupts. This solves both the cpu_online vs. cpu_active problem and the affinity setting of the per cpu timers.

In that case, we don't receive the interrupt (because they are disabled), but _start() sees that the DMA is stopped, so it starts it. The problem is that it sends the transaction that has just finished again, because pl330_update() hasn't mark it as done yet. This patch fixes this race condition by not calling _start() if the DMA is already executing transactions. When interrupts are reenabled, pl330_update() will call _start().

One of the problems is that the ARM implementation doesn't report the function with the BUG() in it, but always reports the PC being in __bug(). The generic implementation doesn't have this problem. Currently we get something like: kernel BUG at fs/proc/breakme.c:35! Unable to handle kernel NULL pointer dereference at virtual address 00000000 ... PC is at __bug+0x20/0x2c With this patch it displays: kernel BUG at fs/proc/breakme.c:35! Internal error: Oops - undefined instruction: 0 [#1] PREEMPT SMP ... PC is at write_breakme+0xd0/0x1b4 This implementation uses an undefined instruction to implement BUG, and sets up a bug table containing the relevant information. Many versions of gcc do not support %c properly for ARM (inserting a # when they shouldn't) so we work around this using distasteful macro magic. v1: Initial version to replace existing ARM BUG() implementation with something more similar to other architectures. v2: Add Thumb support, remove backtrace whitespace output changes. Change to use macros instead of requiring the asm %d flag to work (thanks to Dave Martin <dave.martin@linaro.org>) v3: Remove old BUG() implementation in favor of this one. Remove the Backtrace: message (will submit this separately). Use ARM_EXIT_KEEP() so that some architectures can dump exit text at link time thanks to Stephen Boyd <sboyd@codeaurora.org> (although since we always define GENERIC_BUG this might be academic.) Rebase to linux-2.6.git master. v4: Allow BUGS in modules (these were not reported correctly in v3) (thanks to Stephen Boyd <sboyd@codeaurora.org> for suggesting that.) Remove __bug() as this is no longer needed. v5: Add %progbits as the section flags.
