[alsa-devel] [PATCH v2 5/7] OMAP: sdp4430: Add fixed regulator for twl6040 needs

Peter Ujfalusi peter.ujfalusi at ti.com
Tue Feb 7 14:01:16 CET 2012


The twl6040 VIO power is connected to SMPS V1V8, the
V2V1 power is coming from SMPS V2V1 of twl6030.
These are fixed, always on regulators.
Create fixed voltage regulators for these supplies.
