twl6030: regulator: Configure STATE register instead of REMAP
This is no REMAP register on twl6030, instead there is a STATE register to drive a resource to a given state. The state register can be used to specify what state the resource should enter when its associated with a GRP. Register Bit field description is as below. The patch programmes the corresponding STATE registers for all LDO's to turn ON when assocaited with GRP_P1. STATE REG: Bit7 |Bit6 |Bit5 |Bit4 |Bit3 |Bit2 |Bit1 |Bit0 P3_GRP |P2_GRP |P1_GRP |RES |RES |RES |State1 |State0 State can be specified as below 00: OFF 01: ON 10: OFF 11: SLEEP Signed-off-by: Rajendra Nayak <rnayak@ti.com> Cc: Liam Girdwood <lrg@slimlogic.co.uk> Cc: Samuel Ortiz <sameo@linux.intel.com> Cc: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
