2020-08-13mb/google/zork: Disable ACP I2S wake for schematic version 3.6+Furquan Shaikh
Starting with v3.6 of reference schematics, headphone jack interrupt is moved to a standard GPIO instead of using CODEC_GPI. Thus, we no longer need I2S wake to be enabled in the ACP for boards using v3.6+ version of schematics. This change sets `acp_i2s_wake_enable` and `acp_pme_enable` to default 0 in baseboard devicetrees and overrides to 1 in update_hp_int_odl() if the board is still using older version of reference schematics.

2020-08-06mb/google/zork: Add touchscreen power controlFurquan Shaikh
This change adds support for touchscreen power control using: * GPIO_90 for trembyle based boards * GPIO_32 for dalboz based boards By default, baseboard tables configure these GPIOs as PAD_GPO driven low and override trees expose these pads as enable_gpio to be used by ACPI power resource. In order to support pre-v3.6 boards, override tables configure these pads as PAD_NC and drop the enable_gpio setting from device tree based on board version.

2020-08-06mb/google/zork: Switch USI_RESET to active low polarity for v3.6+Furquan Shaikh
v3.6 of reference schematics have switched the polarity of reset signal to touchscreen controller from active high to active low. This change updates the default configuration in baseboard gpio tables to set the reset GPIO to output low and override tables in variants to set the reset GPIO to output high. Additionally, devicetree by default exposes ACTIVE_LOW configuration for reset GPIO. In order to support pre-v3.6 boards, reset GPIO is updated to ACTIVE_HIGH based on board version.

2020-07-13mb/google/zork: Fix check for variant_uses_v3_schematics()Furquan Shaikh
CB:43224 ("mb/google/zork: Add helpers for v3 schematics and wifi power enable") added helper functions for determining if a board uses v3 schematics. However, it introduced a regression by adding a wrong check for variant_uses_v3_schematics() in variant_audio_update(). This change fixes the check to ensure that dmic_gpio is updated when variant is not using v3 schematics. BUG=b:161141258,b:161128964 TEST=Verified on trembyle that trackpad works again (it was broken because of the regression).

2020-07-08mb/google/zork: Add helpers for v3 schematics and wifi power enableFurquan Shaikh
This change adds following two helper functions: 1. variant_uses_v3_schematics() - Check whether the variant is using v3 version of schematics. 2. variant_has_active_low_wifi_power() - Check whether the variant is using active low power enable for WiFi. In addition to this, Kconfig options are reorganized to add two new configs - VARIANT_SUPPORTS_PRE_V3_SCHEMATICS and VARIANT_SUPPORTS_WIFI_POWER_ACTIVE_HIGH. This allows the helper functions to return `true` early without checking for board version. Eventually, when a variant decides to drop support for pre-v3 schematics, it can be dropped from selecting VARIANT_SUPPORTS_PRE_V3_SCHEMATICS. Similarly, when the variant decides to drop support for active high power enable for WiFi, it can be dropped from selecting VARIANT_SUPPORTS_WIFI_POWER_ACTIVE_HIGH.

2020-07-02mb/google/zork: Generate I2SM ACPI device at runtimeFurquan Shaikh
This change moves the generation of I2SM ACPI device from static asl file to runtime generation by ACP device driver. dmic_select_gpio is set to match version 3+ of Trembyle and Dalboz schematics. In order to maintain backward compatibility, dmic_select_gpio is updated at runtime using variant_audio_update for board versions that are prior to version 3 of reference schematics. The only difference from static generation is that the device I2SM is added under ACPD (i.e. ACP device) instead of CREC (Chrome EC device). It does not make any functional difference from the kernel perspective. BUG=b:157603026 TEST=Verified that the following device gets generated in SSDT: Scope (\_SB.PCI0.PBRA.ACPD) { Device (I2SM) { Name (_HID, "AMDI5682") // _HID: Hardware ID Name (_UID, One) // _UID: Unique ID Name (_DDN, "I2S machine driver") // _DDN: DOS Device Name Method (_STA, 0, NotSerialized) // _STA: Status { Return (0x0F) } Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings { GpioIo (Exclusive, PullDefault, 0x0000, 0x0000, IoRestrictionOutputOnly, "\\_SB.GPIO", 0x00, ResourceConsumer, , ) { // Pin list 0x000D } }) Name (_DSD, Package (0x02) // _DSD: Device-Specific Data { ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301") /* Device Properties for _DSD */, Package (0x01) { Package (0x02) { "dmic-gpios", Package (0x04) { \_SB.PCI0.PBRA.ACPD.I2SM, Zero, Zero, Zero } } } }) } } Verified audio via speakers and mic input.
