thermal: add Intel BXT WhiskeyCove PMIC thermal driver
PATCH v5 1/1 thermal: add Intel BXT WhiskeyCove PMIC thermal driver
This change adds support for Intel BXT Whiskey Cove PMIC thermal driver which is intended to handle the alert interrupts triggered upon thermal trip point cross and notify the thermal framework appropriately with the zone, temp, crossed trip and event details.
---
Changes in v5:
- Applied patch Joe Perches <[email protected]> and reduced data segment size
- Applied patch from Julia Lawall <[email protected]> and fixed the platform_device_id to NULL entry terminated error
Changes in v4:
- Fixed copyright year and changed GPL to GPL v2
Changes in v3:
- Moved driver data from mfd domain to the driver
- Minor coding style related cleanup
Changes in v2:
- Removed unnecessary request_threaded_irq() - we should be only using devm_request_threaded_irq() with virq
