| 2010-02-04 | davinci: cpuidle: move mapping of DDR2 controller registers out of driver | Sekhar Nori | |
| When suspend is supported, both cpuidle and suspend code need to work on DDR2 registers. Instead of mapping the DDR2 registers twice, do it once outside of cpuidle driver and let cpuidle driver get the virtual base address of DDR2 registers.

| 2009-11-25 | davinci: add CPU idle driver | Sekhar Nori | |
| The patch adds support for DaVinci cpu idle driver. Two idle states are defined: 1. Wait for interrupt 2. Wait for interrupt and DDR self-refresh (or power down) Some DaVinci SoCs support putting DDR in self-refresh (eg Dm644x, DM6467) while others support putting DDR in self-refresh and power down (eg DM35x, DA8xx). Putting DDR (or mDDR) in power down saves more power than self-refresh. The patch has been tested on DA850/OMAP-L138 EVM.
