sh: allow runtime pm without suspend/resume callbacks

2009-12-04T04:42:37+00:00

This patch updates the Runtime PM code for SuperH Mobile
to allow drivers to have NULL as pm or callback value.
With this in place there is no need for no-op functions.

sh: Use RSMEM for sleep code on sh7724

2009-10-30T05:38:33+00:00

Use RSMEM instead of ILMEM for sleep mode code storage on SH7724.
This allows us to use R-standby mode on SH7724.

sh: Add MMU and Cache handling sleep mode code

2009-10-30T05:37:56+00:00

Add MMU and cache handling functionality to the SuperH Mobile
sleep code. The MMU and cache registers are saved and restored.
The MMU is disabled and the cache is flushed and disabled before
entering sleep modes if the SUSP_SH_MMU flag is set. This flag
should be set in the case of R-standby and most likely for future
U-standby support as well.

sh: Keep track of allowed sleep modes

2009-10-30T05:37:42+00:00

Add code to keep track of supported sleep modes. This to
only export cpuidle modes that are backed by board support
code. Also, do not allow suspend-to-ram if sdram board code
is missing.

sh: Rework SuperH Mobile sleep mode code

2009-10-30T05:36:52+00:00

Rework the SuperH Mobile sleep code from including
board specific code to allowing each board to provide
pre/post code snippets. These snippets should contain
sdram management code to enter and leave self-refresh.

sh: Allow boards to register memory pre/post sleep code

2009-10-30T02:55:24+00:00

Add code to allow boards registering self-contained
functions for going to/from self-refresh. At this
point the board code is unused. When all supported
boards have been converted then the new sleep code
will make use of these functions.

sh: Add notifiers chains for cpu/board code

2009-10-30T02:54:59+00:00

This patch adds atomic notifier chains for pre/post
sleep events. Useful for cpu code and boards that
need to save and restore register state before and
after entering a sleep mode.
