2022-09-19	soc/amd/mendocino: Add VRM limit DPTC registers	Tim Van Patten
	Add VRM DPTC limit registers. These are required when throttling the SOC for low/no battery mode to prevent the SOC from overwhelming the charger. b/245942343 is tracking passing these additional fields to the FSP and having the FSP configure them.

2022-09-15	amd/mendocino: Control DPTC with only Kconfig	Tim Van Patten
	SOC_AMD_COMMON_BLOCK_ACPI_DPTC can be enabled conditionally for any skyrim boards, similar to mainboard/google/zork/Kconfig. This makes the value dptc_tablet_mode_enable redundant. This CL removes dptc_tablet_mode_enable so DPTC is controlled entirely with the Kconfig value SOC_AMD_COMMON_BLOCK_ACPI_DPTC. This means DPTC is only included for boards that actually enable it.

2022-09-12	soc/amd: Remove unsupported DPTC tablet mode settings	Tim Van Patten
	The following boards are setting DTPC tablet mode values without corresponding device tree values, meaning they are effectively setting "random" values for tablet mode: 1. Cezanne 2. Mendocino The device tree has tablet mode disabled, so the code should never be exercised, but this CL removes it entirely to cleanup "dead" code.

2022-09-12	soc/amd: Refactor DPTC Tablet Mode	Tim Van Patten
	Refactor AMD DPTC tablet mode in preparation for adding low/no battery DPTC settings. 1. Refactor and simplify acpigen_write_alib_dptc() into the following functions: - acpigen_write_alib_dptc_default() - acpigen_write_alib_dptc_tablet() 2. Add device tree register value dptc_tablet_mode_enable to control whether DPTC tablet mode is enabled for a variant. 3. Add dptc.asl to perform the necessary ACPI checking before modifying the DPTC settings.

2022-08-18	soc/amd/mendocino: enable CPPC feature	Felix Held
	This is sort-of reverts commit cbf290c692b2 ("soc/amd/sabrina: drop CPPC code"), since it turned out that the CPPC feature is supported on Sabrina (now Mendocino) despite this being missing from the documentation I looked at when writing the patch referenced above. Since the CPPC ACPI code generation functionality has been moved to common code, this isn't a direct revert.

2022-08-11	treewide: Rename Sabrina to Mendocino	Jon Murphy
	'Mendocino' was an embargoed name and could previously not be used in references to Skyrim. coreboot has references to sabrina both in directory structure and in files. This will make life difficult for people looking for Mendocino support in the long term. The code name should be replaced with "mendocino".
