Hi everyone,
this patch adds the DT for the [[Inet-K970] tablet.
Note that the wiki page has been renamed from [[Tristan-Auron-Planet-1]]
after identifying the mainboard. Earlier patches concerning U-Boot and
FEX have been filed under original name to this list and are now somewhat
in limbo. FEX is checked in, U-Boot on hold to the best of my knowledge.
Should I post a rename patch for the FEX and repost the unchanged U-boot
patch for the device under the new name or how to proceed best?
Kind regards, Lars
