2021-07-15soc/intel/alderlake: Add virtual GPIOs for community 1Maulik V Vaghela
Alder Lake SoC has virtual GPIOs for community 1 which was being programmed by FSP and hence was skipped by coreboot. As part of moving most of the GPIO programming to coreboot, we're skipping this programming in FSP now. TEST=Check register offset to see if programming is correct.

2021-05-14soc/intel/alderlake: Add known GPIO virtual wire informationDeepti Deshatty
GPIO communities 0, 1, and 4 have virtual wire indexes & bits for at least some of their groups; add the known information into the community definitions. This patch is ported form tigerlake.

2021-05-05soc/intel/alderlake: Add GPIO definition for CPU PCIe vGPIOMaulik V Vaghela
Adding GPIO definition for community 3 which is CPU reserved GPIO used by CPU side PCIe root ports. We did not have this definition since FSP used to program this GPIOs. Now, instead of FSP, coreboot programs CPU PCIe GPIOs for CLKSRC and lanes to put GPIOs in native mode. Thus adding definition of this virtual GPIOs in this CL. BUG=None BRANCH=None TEST=Check if correct registers are being programmed Change-Id: I481ea7e3ba948bf6d37b97d08c675a18ee68125d Signed-off-by: Maulik V Vaghela <maulik.v.vaghela@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/52783 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org>
2021-03-27soc/intel/alderlake: Correct GPE DWx assignment as per EDSSubrata Banik
List of changes: 1. Update GPIO Group to GPE DWx assignment encoding as per MISCCFG register per GPIO Community. 2. PMC_GPP_* macros are also updated as per GPIO_CFG register in PMC space. BUG=b:183464235 TEST=Able to fix the TPM IRQ issue on SM.

2020-09-27soc/intel/alderlake: Add GPIOs for Alder Lake SOCSubrata Banik
Add definitions for the GPIO pins on Alder Lake LP, as well as GPIO IRQ routing information and supporting ACPI ASL. For now, add the following 5 GPIO communities and 13 GPIO groups: Comm. 0: GPP_B, GPP_T, GPP_A Comm. 1: GPP_S, GPP_H, GPP_D Comm. 2: GPD Comm. 4: GPP_C, GPP_F, GPP_E, GPP_HVMOS Comm. 5: GPP_R, GPP_SPI0 Change-Id: I77b9dcc46aceaf530e2054c9cacd7b026ebbb96b Signed-off-by: Subrata Banik <subrata.banik@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/45571 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Michael Niewöhner <foss@mniewoehner.de>
