mfd: tps68470: Remove tps68470 MFD driver This driver only covered one scenario in which ACPI devices with _HID INT3472 are found, and its functionality has been taken over by the intel-skl-int3472 module, so remove it.

ACPI / PMIC: Move TPS68470 OpRegion driver to drivers/acpi/pmic/ It is revealed now that TPS68470 OpRegion driver has been added in slightly different scope. Let's move it to the drivers/acpi/pmic/ folder for sake of the unification.

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: PMIC: Add pmic_i2c_address to BYT Crystal Cove support Add a pmic_i2c_address entry to intel_pmic_bytcrc.c, so that intel_soc_pmic_exec_mipi_pmic_seq_element() can be used on devices with a Bay Trail Crystal Cove PMIC OpRegion driver.

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: xpower: Fix _TMP ACPI errors On some devices with a X-Powers AXP288 PMIC the LPAT tables in the ACPI node for the AXP288 PMIC for some reason only describe a small temperature range, e.g. 27° - 37° Celcius (assuming the entries are in millidegrees). When the tablet is idle in a room at 21° degrees this is causing values outside the LPAT table to be read, causing e.g. the following 2 errors to get spammed to the logs every 4 seconds! : [ 7512.791316] ACPI Error: AE_ERROR, Returned by Handler for [UserDefinedRegion] (20210930/evregion-281) [ 7512.791611] ACPI Error: Aborting method \_SB.SXP1._TMP due to previous error (AE_ERROR) (20210930/psparse-529) Fix this by clamping the raw value to the LPAT table range before passing it to acpi_lpat_raw_to_temp(). Note clamping has been chosen rather then extrapolating because it is unknown how other parts of the ACPI tables will respond to temperature values outside of the LPAT range.
