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. config PWM_DW_BASE_ADDR hex "DesignWare PWM Base Address" depends on PWM_DW help Specify the base address for registers for DesignWare PWM. config PWM_DW_NUM_PORTS 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.
