ASoC: Intel: sof_es8336: Add DMI quirk for Huawei BOD-WXX9
Add DMI entry for Huawei Matebook D (BOD-WXX9) with HEADPHONE_GPIO and DMIC quirks. This device has ES8336 codec with: - GPIO 16 (headphone-enable) for headphone amplifier control - GPIO 17 (speakers-enable) for speaker amplifier control - GPIO 269 for jack detection IRQ - 2-channel DMIC Hardware investigation shows that both GPIO 16 and 17 are required for proper audio routing, as headphones and speakers share the same physical output (HPOL/HPOR) and are separated only via amplifier enable signals. RFC: Seeking advice on GPIO control issue: GPIO values change in driver (gpiod_get_value() shows logical value changes) but not physically (debugfs gpio shows no change). The same gpiod_set_value_cansleep() calls work correctly in probe context with msleep(), but fail when called from DAPM event callbacks. Context information from diagnostics: - in_atomic=0, in_interrupt=0, irqs_disabled=0 - Process context: pipewire - GPIO 17 (speakers): changes in driver, no physical change - GPIO 16 (headphone): changes in driver, no physical change In Windows, audio switching works without visible GPIO changes, suggesting possible ACPI/firmware involvement. Any suggestions on how to properly control these GPIOs from DAPM events would be appreciated.
