| * [ARM] pxa: Avoid fiddling with CKEN register on suspendRussell King2008-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PXA manuals indicate that when in standby or sleep modes, clocks to peripherals are shut off by the processor itself. Eg: PXA270 standby: "In standby mode, all clocks are disabled except those for the power manager and the RTC." PXA270 sleep: "In sleep mode, all clocks are disabled to the processor and to all peripherals except the RTC." PXA255 sleep: "In Sleep Mode, all processor and peripheral clocks are disabled, except the RTC." Therefore, it should be safe to leave the clock enable register alone prior to entering low power modes for these SoCs. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* 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.

* PM: Move definition of struct pm_ops to suspend.hRafael J. Wysocki2007-10-18
| | | | | | | | | | | | | | | | | | | | | | Move the definition of 'struct pm_ops' and related functions from <linux/pm.h> to <linux/suspend.h> . There are, at least, the following reasons to do that: * 'struct pm_ops' is specifically related to suspend and not to the power management in general. * As long as 'struct pm_ops' is defined in <linux/pm.h>, any modification of it causes the entire kernel to be recompiled, which is unnecessary and annoying. * Some suspend-related features are already defined in <linux/suspend.h>, so it is logical to move the definition of 'struct pm_ops' into there. * 'struct hibernation_ops', being the hibernation-related counterpart of 'struct pm_ops', is defined in <linux/suspend.h> .

* [ARM] 4489/1: pxa: split pxa_cpu_suspend to processor specific onesEric Miao2007-07-20
| | | | | | | | | | | | | | | | 1. split pxa_cpu_suspend to pxa25x_cpu_suspend and pxa27x_cpu_suspend and make pxa25x_cpu_pm_enter() and pxa27x_cpu_pm_enter() to invoke the corresponding _suspend functions, thus remove all those ugly #ifdef .. #endif out of sleep.S 2. move the declarations of those suspend functions to pm.h note: this is not a clean enough solution until all the pxa25x and pxa27x specific part is further removed out of sleep.S, sleep.S is supposed to contain generic code only Signed-off-by: eric miao <eric.y.miao@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 4488/1: pxa: move pxa25x/pxa27x specific code out of pm.cEric Miao2007-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. introduce a structure pxa_cpu_pm_fns for pxa25x/pxa27x specific operations as follows: struct pxa_cpu_pm_fns { int save_size; void (*save)(unsigned long *); void (*restore)(unsigned long *); int (*valid)(suspend_state_t state); void (*enter)(suspend_state_t state); } 2. processor specific registers saving and restoring are performed by calling the corresponding (*save) and (*restore) 3. pxa_cpu_pm_fns->save_size should be initialized to the required size for processor specific registers saving, the allocated memory address will be passed to (*save) and (*restore) memory allocation happens early in pxa_pm_init(), and save_size should be assigned prior to this (which is usually true, since pxa_pm_init() happens in device_initcall() 4. there're some redundancies for those SLEEP_SAVE_XXX and related macros, will be fixed later, one way possible is for the system devices to handle the specific registers saving and restoring Signed-off-by: eric miao <eric.y.miao@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] 4451/1: pxa: make dma.c generic and remove cpu specific dma codeEric Miao2007-07-12
| | | | | | | | | | | | | | | | | | | | | | Since the number of dma channels varies between pxa25x and pxa27x, it introduces some specific code in dma.c. This patch moves the specific code to pxa25x.c and pxa27x.c and makes dma.c more generic. 1. add pxa_init_dma() for dma initialization, the number of channels are passed in by the argument 2. add a "prio" field to the "struct pxa_dma_channel" for the channel priority, and is initialized in pxa_init_dma() 3. use a general priority comparison with the channels "prio" field so to remove the processor specific pxa_for_each_dma_prio macro, this is not lightning fast as the original one, but it is acceptable as it happens when requesting dma, which is usually not so performance critical Signed-off-by: eric miao <eric.miao@marvell.com> Acked-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] pxa: Fix PXA27x suspend type validation, remove pxa_pm_prepare()Russell King2007-07-12
| | | | | | | | | | | | | | pxa_pm_prepare() tried to validate the suspend method type. As noted in previous commits: eb9289eb20df6b54214c45ac7c6bf5179a149026 9c372d06ce9ddf65e1393f9ea22a6d6bd5f96b42 e8c9c502690efd24b7055bf608e7a3c34216848b the checking of the suspend type in the 'prepare' method is the wrong place to do this; use the 'valid' method instead.

* [ARM] 2787/2: PXA27x low power modes supportTodd Poynor2005-10-28
| | | | | | | | | | | | | | | | | | | Patch from Todd Poynor Add symbols for PXA2xx PWRMODE register M field that selects low-power mode, replace unadorned constants. Honor power mode parameter of pxa_cpu_suspend(mode), no longer force to 3 (sleep). Full Deep Sleep low-power mode support for PXA27x is pending generic PM interfaces to select more than 2 suspend-to-RAM-style power modes, but this is expected soon. This can be hardcoded in the meantime by replacing the pxa_cpu_suspend() parameter value. From David Burrage and Todd Poynor. Try #2 removes one of the register copies and moves the code to save the pxa_cpu_suspend parameter to immediately surround the call that requires the parameter value be preserved.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
