Linus Walleij	897a6a1a14	ARM: davinci: fix cache flush build error ... The TNET variant of DaVinci compiles some code that it shares with other DaVinci variants, however it has a V6 CPU rather than an ARM926T, thus the hardcoded call to arm926_flush_kern_cache_all() in sleep.S will obviously fail, and we need to build with the v6_flush_kern_cache_all() call instead. This was triggered by manually altering the DaVinci config to build the TNET version.

Sekhar Nori	efc1bb8a6f	davinci: add power management support ... This patch adds core power management (suspend-to-RAM) support for DaVinci SoCs. The code depends on the the "deepsleep" feature to suspend the SoC and saves power by gating the input clock. The wakeup can be based on an external event as supported by the SoC. Assembly code (in sleep.S) is added to aid gating DDR2 clocks. Code doing this work should not be accessing DDR2. The assembly code is relocated to SRAM by the code in pm.c The support has been validated on DA850/OMAP-L138 only though the code is (hopefully) generic enough that other SoCs supporting deepsleep feature simply requires SoC specific code to start using this driver. Note that all the device drivers don't support suspend/resume still and are being worked on.
