2013-06-18ARM: dts: TWL4030: fix mux and wakeup for SYS_NIRQ lineKevin Hilman
On most OMAP3 platforms, the twl4030 IRQ line is connected to the SYS_NIRQ line on OMAP. Add another DTS include file (twl4030_omap3.dtsi) for boards that hook up the twl4030 this way to include. This allows RTC wake from off-mode to work again on OMAP3-based platforms with twl4030. Tested on 3530/Beagle, 3730/Beagle-xM, 3530/Overo, 3730/Overo-STORM.

2013-06-18ARM: dts: omap5: Make uevm as the official board and deprecate sevm supportSricharan R
The uevm is the only official board supported for the OMAP5 soc in mainline. The existent sevm platform will no more be supported. Hence cleaning up the board dts file to have only the data required for uevm. Renaming the board dts file and adding the following cleanups. * There are no devices connected on I2C 2,3,4 buses. So remove the pinmux data for the same. * OMAP5432 and DDR3 memory is used in the uevm. Temperature polling is not supported with DDR3 memories. Because of DDR3 phy limitation the voltage change across DVFS and all shadow registers for DVFS on DDR3 is not supported. Hence the emif kernel driver is not required, so removing the DDR3 device file and emif nodes for uevm. * Keypad is not supported on uevm. So remove the device node.
