2020-10-26mb/google/zork: Update style of check on cbi return valuesEric Lai
Since google_chromeec_cbi_get_board_version and google_chromeec_cbi_get_fw_config both call cbi_get_unit32 and return 0 as success, non-zero as failure. Let's add more readability for the false condition.

2020-08-06mb/google/zork: Configure GPIO_89 as PAD_NCFurquan Shaikh
GPIO_89 was marked as EN_DEV_BEEP_L in pre-v3.6 schematics, but it was never really used on any of the zork variants. Starting with v3.6, GPIO_89 is left unused in schematics. This change configures GPIO_89 as PAD_NC in baseboard GPIO table. Since EN_DEV_BEEP_L still needs to be driven high to allow speakers to work, GPIO_89 is configured as PAD_GPO driven high on pre-v3.6 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.
