ACPI / LPSS: Add Intel BayTrail ACPI mode PWM (e1c74817) · Commits · 戴 / test

Intel BayTrail LPSS consists of two PWM controllers which can be enumerated from ACPI namespace. This change will cause platform device objects to be created for Intel BayTrail PWM controllers which will allow the pwm-lpss driver to bind to them and handle those devices. Signed-off-by:
