386 | * Some Cherry Trail boards with an ES8316 codec have a bug in their | |
387 | * ACPI tables where the MSSL1680 touchscreen's _PS0 and _PS3 methods | |
388 | * wrongly also set the speaker-enable GPIO to 1/0. Testing has shown | |
389 | * that this really is a bug and the GPIO has no influence on the | |
390 | * touchscreen at all. | |
391 | * | |
392 | * The silead.c touchscreen driver does not support runtime suspend, so | |
393 | * the GPIO can only be changed underneath us during a system suspend. | |
394 | * This resume() function runs from a pm complete() callback, and thus | |
395 | * is guaranteed to run after the touchscreen driver/ACPI-subsys has | |
396 | * brought the touchscreen back up again (and thus changed the GPIO). | |
397 | * | |
398 | * So to work around this we pass GPIOD_FLAGS_BIT_NONEXCLUSIVE when | |
399 | * requesting the GPIO and we set its value here to undo any changes | |
400 | * done by the touchscreen's broken _PS0 ACPI method. | |
