* [ARM] 4987/1: S3C24XX: Ensure watchdog reset initiated from cached code.Ben Dooks2008-04-17
| | | | | | | | | | | | | | There seems to be some problem with at-least the S3C2440 and bus traffic during an reset. It is unlikely, but still possible that the system will hang in such a way that the watchdog cannot get the system out of the state it is in. Change to making the code that calls the watchdog reset run from cached memory so that instruction fetches have quiesced before the watchdog fires.

* PM: Rename struct pm_ops and related thingsRafael J. Wysocki2007-10-18
| | | | | | | | | | | | | | | | The name of 'struct pm_ops' suggests that it is related to the power management in general, but in fact it is only related to suspend.  Moreover, its name should indicate what this structure is used for, so it seems reasonable to change it to 'struct platform_suspend_ops'.  In that case, the name of the global variable of this type used by the PM core and the names of related functions should be changed accordingly.

This patch implements a generic pm_valid_only_mem function that is then exported for users and puts it to use in almost all existing pm_ops.

* | rework pm_ops pm_disk_mode, kill misuseJohannes Berg2007-04-30
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch series cleans up some misconceptions about pm_ops. Some users of the pm_ops structure attempt to use it to stop the user from entering suspend to disk, this, however, is not possible since the user can always use "shutdown" in /sys/power/disk and then the pm_ops are never invoked. Also, platforms that don't support suspend to disk simply should not allow configuring SOFTWARE_SUSPEND (read the help text on it, it only selects suspend to disk and nothing else, all the other stuff depends on PM). The pm_ops structure is actually intended to provide a way to enter platform-defined sleep states (currently supported states are "standby" and "mem" (suspend to ram)) and additionally (if SOFTWARE_SUSPEND is configured) allows a platform to support a platform specific way to enter low-power mode once everything has been saved to disk. This is currently only used by ACPI (S4). This patch: The pm_ops.pm_disk_mode is used in totally bogus ways since nobody really seems to understand what it actually does. This patch clarifies the pm_disk_mode description. It also removes all the arm and sh users that think they can veto suspend to disk via pm_ops; not so since the user can always do echo shutdown > /sys/power/disk, they need to find a better way involving Kconfig or such. ACPI is the only user left with a non-zero pm_disk_mode. The patch also sets the default mode to shutdown again, but when a new pm_ops is registered its pm_disk_mode is selected as default, that way the default stays for ACPI where it is apparently required.

* [ARM] 4220/1: S3C24XX: DMA system initialised from sysdevBen Dooks2007-02-17
| | | | | | | | | | | | | | | This patch gets the DMA system for the S3C24XX ready for the S3C2443, which requires 6 dma channels at a different stride, and different base IRQ. The DMA system is now initialised from the same drivers which apply the DMA mappings, as well as removing the DMA sysdev intialisation out of the main init code (which is now being called from a sysdev probe, so cannot add a new sysdev) Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
