ACPI / PMIC: Add TI PMIC TPS68470 operation region driver
The Kabylake platform coreboot (Chrome OS equivalent of BIOS) has defined 4 operation regions for the TI TPS68470 PMIC. These operation regions are to enable/disable voltage regulators, configure voltage regulators, enable/disable clocks and to configure clocks. This config adds ACPI operation region support for TI TPS68470 PMIC. TPS68470 device is an advanced power management unit that powers a Compact Camera Module (CCM), generates clocks for image sensors, drives a dual LED for flash and incorporates two LED drivers for general purpose indicators. This driver enables ACPI operation region support to control voltage regulators and clocks for the TPS68470 PMIC.

This config adds ACPI operation region support for TI TPS68470 PMIC.
|
||||||
|
TPS68470 device is an advanced power management unit that powers
|
||||||
|
a Compact Camera Module (CCM), generates clocks for image sensors,
|
||||||
|
drives a dual LED for flash and incorporates two LED drivers for
|
||||||
|
general purpose indicators.
|
||||||
|
This driver enables ACPI operation region support control voltage
|
||||||
|
regulators and clocks.
|
||||||
|
|
||||||
|
This option is a bool as it provides an ACPI operation
|
||||||
|
region, which must be available before any of the devices
|
||||||
|
using this, are probed.
