[PATCH v4 0/2] Handle shared reset GPIO for WSA883x speakers

Posted by Mohammad Rafi Shaik 1 month, 4 weeks ago

On some Qualcomm platforms such as QCS6490-RB3Gen2, the multiple
WSA8830/WSA8835 speakers share a common reset (shutdown) GPIO.
To handle such cases, use the reset controller framework along with the
"reset-gpio" driver.

Tested on:
	- QCS6490-RB3Gen2

changes in [v4]:
	- Dropped v3-0002 patch, which is not required.
	  Fixed with proper error handling for failure cases.
	- Link to V3: https://lore.kernel.org/linux-arm-msm/20250727083117.2415725-1-mohammad.rafi.shaik@oss.qualcomm.com/

changes in [v3]:
	- Created separate patch for devm action to safely disable
	  regulator.
	- cleanup the v2-0002 patch.
	- Link to V2: https://lore.kernel.org/linux-sound/20250718104628.3732645-1-mohammad.rafi.shaik@oss.qualcomm.com/

changes in [v2]:
	- Addressed the review comments from Krzysztof, Dmitry, Philipp.
	- Used devm_reset_control_get_optional_shared_deasserted() api.
	- created deasserts/asserts functions to handle reset gpios.
	- Register devm action to safely disable the regulator on device removal.
	- Link to V1: https://lore.kernel.org/linux-sound/20250620103012.360794-1-mohammad.rafi.shaik@oss.qualcomm.com/
