* ACPI / PMIC: modify the pen function signature to take bit fieldBin Gao2016-06-24
| | | | | | | | | | | | | | | | Issue description: On some pmics, the policy enable for thermal alerts refers to different bit fields of the same registers, whereas on other pmics, the policy enable refers to the same bit field on different registers. Previous implementation did not provide the flexibility for supporting the first approach. Solution: Modified the policy enable function to take bit field as well. The use of bit field is left to the pmic specific opregion driver.

* ACPI / PMIC: support PMIC operation region for CrystalCoveAaron Lu2014-11-26
The Baytrail-T platform firmware has defined two customized operation regions for PMIC chip Crystal Cove - one is for power resource handling and one is for thermal: sensor temperature reporting, trip point setting, etc. This patch adds support for them on top of the existing Crystal Cove PMIC driver. The reason to split code into a separate file intel_pmic.c is that there are more PMIC drivers with ACPI operation region support coming and we can re-use those code. The intel_pmic_opregion_data structure is created also for this purpose: when we need to support a new PMIC's operation region, we just need to fill those callbacks and the two register mapping tables.
