* [ARM] pxa: add preliminary suspend/resume code for pxa3xxeric miao2008-02-041-0/+102
| | | | | | | | | | 1. clear RDH bit after resuming back from D3, otherwise, the multi function pins will retain the low power state 2. save/restore essential system registers Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] pxa: omit PXA25x or PXA27x standby/sleep code as appropriateRussell King2008-01-261-2/+6
| | | | | | | There's no point building standby/sleep code for processors which aren't configured. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] pxa: move memory controller registers into pxa2xx-regs.hRussell King2008-01-261-0/+1
| | | | | | | PXA3 has a different memory controller from PXA2 platforms. Avoid clashing definitions by moving the PXA2 definitions to pxa2xx-regs.h Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] pxa: don't rely on r2 being preserved over a function callRussell King2008-01-201-4/+2
| | | | | | | | r2 is not guaranteed to be preserved over a function call, so relying on it to store the link register over the call to sleep_phys_sp() is unreliable. Store the link register on the stack instead. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 4489/1: pxa: split pxa_cpu_suspend to processor specific onesEric Miao2007-07-201-39/+73
| | | | | | | | | | | | | | | | 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] Remove MODE_(SVC|IRQ|FIQ|USR) and DEFAULT_FIQRussell King2006-06-251-1/+1
| | | | | | | DEFAULT_FIQ was entirely unused. MODE_* are just redefinitions of *_MODE. Use *_MODE instead. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 2787/2: PXA27x low power modes supportTodd Poynor2005-10-281-2/+5
| | | | | | | | | | | | | | | | | | | 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.

* [PATCH] ARM: 2650/1: PXA27x sleep - workaround Errata 39 & 50 (Patch 2667)Jeff Lackey2005-04-251-6/+50
| | | | | | | | | | Patch from Jeff Lackey This patch updates arch/arm/mach-pxa/sleep.S to support the PXA270 CPU. It works around Errata 39 & 50 from the Intel(R) PXA27x Processor Family Specification Update. Signed-off-by: Jeff Lackey Signed-off-by: Russell King
* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+194
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!
