From: Sylvain Lemieux <redacted> The PWM_PIN_LEVEL bit is leave unset by the kernel PWM driver. Prior to commit 08ee77b5a5de27ad63c92262ebcb4efe0da93b58, the PWM_PIN_LEVEL bit was always clear when the PWM was disable and a 0 logic level was apply to the output. According to the LPC32x0 User Manual [1], the default value for bit 30 (PWM_PIN_LEVEL) is 0. This change initialize the pin level to 0 (default value) and update the register value accordingly.
