The OMAP5432EVM by SVtronics [1] comes with a twl6037 (and it is supported by mainline device tree omap5-uevm.dts). And we hope that the pyra-handheld.com hardware is finished soon. For hardware bring-up it would be good to already have the gpadc available - so we have some hen-and-egg situation here.
