config PWM_PCA9685_INIT_PRIORITY
	int
	depends on PWM_PCA9685
	default 70
	prompt "Init priority"
	help
	  Device driver initialization priority.

config PWM_PCA9685_0
	bool "PCA9685 PWM chip #0"
	depends on PWM_PCA9685
	default n
	help
	  Enable config options for the PCA9685 I2C-based PWM chip #0.

config PWM_PCA9685_0_DEV_NAME
	string "PCA9685 PWM chip #0 Device Name"

config PWM_DW
	bool "DesignWare PWM"
	depends on PWM
	default n
	help
	  Enable driver to utilize PWM on the DesignWare Timer IP block.
	  Care must be taken if one is also to use the timer feature, as
	  they both use the same set of registers.

config PWM_DW_DEV_NAME
	string "DesignWare PWM Device Name"
	depends on PWM_DW
	default "PWM_DW"
	help
	  Specify the device name for the DesignWare PWM driver.

	int "Number of PWM ports for DesignWare PWM"
	depends on PWM_DW
	default 1
	help
	  Specify how many PWM ports on the IP block.

	  Default is 1.
