* [ARM] 2787/2: PXA27x low power modes supportTodd Poynor2005-10-281-1/+1
| | | | | | | | | | | | | | | | | | | 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: 2781/2: PXA27x Standby mode take 2Todd Poynor2005-07-011-0/+32
Patch from Todd Poynor Add support for PXA27x Standby mode, a low-power mode that retains CPU and some peripheral state (the existing "sleep" mode is a power-power mode that retains less state). Activated via: echo -n standby > /sys/power/state From: David Burrage and Todd Poynor Signed-off-by: Todd Poynor <tpoynor@mvista.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
