ACPI: PMIC: Add comments with DSDT power opregion field names The DSDTs of CHT devices using the Dollar Cove TI PMIC, all use LDO1 - LDO14 names for the DSDT power opregion field names. Add comments with these fields to make it easier to see which PMIC registers are being set by ACPI code using these. Note that LDO4 is missing and the mapped registers jump from 0x43 to 0x45 to match. This matches with how the fields are declared in the DSDT where LDO4 is skipped too. Note there is no hole in the field addresses, LDO4 is simply just not defined on either side.

ACPI: PMIC: allow drivers to provide a custom lpat_raw_to_temp() function The LPAT tables used in the DSDT for some PMICs require special handling, allow the PMIC OpRegion drivers to provide an alternative implementation by adding a lpat_raw_to_temp function pointer to struct pmic_table; and initialize this to the default acpi_lpat_raw_to_temp function for all PMICs.

ACPI: scan: Extend acpi_walk_dep_device_list() The acpi_walk_dep_device_list() function is not as generic as its name implies, serving only to decrement the dependency count for each dependent device of the input. Extend it to accept a callback which can be applied to all the dependencies in acpi_dep_list. Replace all existing calls to the function with calls to a wrapper, passing a callback that applies the same dependency reduction.

ACPI / PMIC: Add opregion driver for Intel Dollar Cove TI PMIC This patch adds the opregion driver for Dollar Cove TI PMIC on Intel Cherry Trail devices. The patch is based on the original work by Intel, found at: https://github.com/01org/ProductionKernelQuilts with many cleanups and rewrites. The driver is currently provided only as built-in to follow other PMIC opregion drivers convention. The re-enumeration of devices at probe is required for fixing the issues on HP x2 210 G2. See bug#195689.
