Subject: davinci: da850/omap-l138 evm: account for DEFDCDC{2,3} being tied high
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8b24599e72c9aee1ea1187e29cb9c5de9f449cce;p=linux-beck.git

davinci: da850/omap-l138 evm: account for DEFDCDC{2,3} being tied high

Per the da850/omap-l138 Beta EVM SOM schematic, the DEFDCDC2 and
DEFDCDC3 lines are tied high. This leads to a 3.3V IO and 1.2V CVDD
voltage.

Pass the right platform data to the TPS6507x driver so it can operate
on the DEFDCDC{2,3}_HIGH register to read and change voltage levels.
