PS9, Line 146: [1] = {.power_gpio = ACPI_GPIO_OUTPUT_ACTIVE_HIGH(GPP_E4),
             : 					       .group = ACPI_PLD_GROUP(3, 1),}}"
should this be under tcss_dma1 ? this is for Type-C Port 3... but then we've got two driver instances in the kernel probably thinking they both have exclusive access to this GPIO......
