2021-03-10	mfd: intel_pmt: Add support for DG1	David E. Box	1	-29/+72
	Adds PMT Telemetry aggregator support for the DG1 graphics PCIe card. The device does not have the DVSEC region in its PCI config space so hard code the discovery table data in the driver. Also requires a fix for DG1 in the Telemetry driver for how the ACCESS_TYPE field is used. Signed-off-by: David E.

2021-03-10	mfd: intel_pmt: Fix nuisance messages and handling of disabled capabilities	David E. Box	1	-8/+3
	Some products will be available that have PMT capabilities that are not supported. Remove the warnings in this instance to avoid nuisance messages and confusion. Also return an error code for capabilities that are disabled by quirk to prevent them from keeping the driver loaded if only disabled capabilities are found.

2020-11-04	mfd: Intel Platform Monitoring Technology support	David E. Box	1	-0/+223
	Intel Platform Monitoring Technology (PMT) is an architecture for enumerating and accessing hardware monitoring facilities. PMT supports multiple types of monitoring capabilities. This driver creates platform devices for each type so that they may be managed by capability specific drivers (to be introduced). Capabilities are discovered using PCIe DVSEC ids. Support is included for the 3 current capability types, Telemetry, Watcher, and Crashlog. The features are available on new Intel platforms starting from Tiger Lake for which support is added. This patch adds support for Tiger Lake (TGL), Alder Lake (ADL), and Out-of-Band Management Services Module (OOBMSM). Also add a quirk mechanism for several early hardware differences and bugs. For Tiger Lake and Alder Lake, do not support Watcher and Crashlog capabilities since they will not be compatible with future product. Also, fix use a quirk to fix the discovery table offset.
