GPO regulators are digital outputs that can be enabled or disabled by a dedicated bit in mc13783 POWERMISC register. In this family can be count in also Power Gates (PWGT1 and 2): enabled by a dedicated pin a Power Gate is an hardware driven supply where the output (PWGTnDRV) follow this law: Bit PWGTxSPIEN | Pin PWGTxEN | PWGTxDRV | Read Back 0 = default | | | PWGTxSPIEN ---------------+-------------+----------+------------ 1 | x | Low | 0 0 | 0 | High | 1 0 | 1 | Low | 0 As read back value of control bit reflects the PWGTxDRV state (not the control value previously written) and mc13783 POWERMISC register contain only regulator related bits, a dedicated function to manage these bits is created here with the aim of tracing the real value of PWGTxSPIEN bits and reproduce it on next writes. All POWERMISC users _must_ use the new function to not accidentally disable Power Gates supplies. v2 changes: -Better utilization of abstraction layers. -Voltage query support. GPO's and PWGTxDRV are fixed voltage regulator with voltage value of 3.1V and 5.5V respectively.
