arm/dts: Add omap3-beagle.dts

Add a minimal dts for original OMAP3430/3530 version of the Beagle board. This version of the Beagle board has 256MB of DDR and features the same TWL4030 power management IC (PMIC) as the Beagle board XM.

Given that the Beagle and Beagle-XM boards use the same PMIC, move the definition of the VSIM regulator into the TWL4030.dtsi file so that we do not need to duplicate in the Beagle board dts file.

This has been boot tested on an OMAP3530 Beagle board and verifing that the SD/MMC interface is working with a SD card.

This patch is generated on top of Tony's patch for adding the Beagle board XM dts file [1].

Hi Jon,

Quoted 3 lines · Jon Hunter

Add a minimal dts for original OMAP3430/3530 version of the Beagle board. This version of the Beagle board has 256MB of DDR and features the same TWL4030 power management IC (PMIC) as the Beagle board XM.

Thanks for the patch.

Given that the Beagle and Beagle-XM boards use the same PMIC, move the definition of the VSIM regulator into the TWL4030.dtsi file so that we do not need to duplicate in the Beagle board dts file.

Good, catch, regulator definition has indeed nothing to do outside the twl4030.dtsi.

This patch is generated on top of Tony's patch for adding the Beagle board XM dts file [1].

Tony has just updated his devel-dt with the DTS series I pushed plus the beagle-xm introduction, so I'm gonna put this one on top and built a for_3.7/dts_part2 branch sinec there are a couplf of USB / AM33xx pending.
