One question inlined for the mmc3, other than that:

Do you happened to know how the audio is connected on the board?
The DM814x-EVM seams to be using McASP2 with aic3106 so it is possible that HP
copied the design from there...

I grepped the sources for it and these are the evtmux channels the original
code is using. So maybe they have some different audio setup, the hacks in the
original board file mention "hdmi-dai".

[PATCH 7/7] ARM: dts: Enable emmc on hp t410

2015-12-03 Thread Tony Lindgren

There's a 2GB emmc on hp t410 that's wired to the sd_2 interface.
Note that we also need to configure the evtmux using edma_xbar for
edma channels.
