[2] [1] Initially I'm not using the register cache offered by regmap, it will come as a followup series [2] When the driver supports more power levels, the bulk_enable/disable will be removed, and the VIO/V2V1 supplies are going to be handled separately. As of now it is better to enable them with the bulk call. Still in the to-do list: Implement proper regulator support on SDP4430, and PandaBoard for the needed supplies by the twl6040. The supply source is the same on both boards: TWL6040 VDD2V1 <- TWL6030 V2V1 SMPS TWL6040 VDDVIO <- TWL6030 V1V8 SMPS There seams to be no control implemented in the regulator driver for these SMPS regulators, so this need to be done first. The reason that I'm sending this series (even when I know that the proper regulator support is missing for SDP4430/PandaBoard) is to get feedback for the rest of the series, so I can include the fixes in the v3 series. ------ Intro mail from the original series: This series will convert the twl6040 MFD driver to an i2c driver. Compared to older twl4030/5030/TPS the twl6040 is a standalone audio IC. It is better if the twl6040-core (and all of it's child devices) does not depend on the twl-core since it has nothing to with it. With this conversion the dependency on twl can be dropped from the twl6040 driver stack (core, vibra, audio). Between the first and second patch the audio will not probe on OMAP4, but I felt it is better this way at least for the first RFC series to not have too big change within one patch. The two patch can be squashed together later if no objections.
