From: Sylvain Lemieux <slemieux at tycoint.com>
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 ,
the default value for bit 30 (PWM_PIN_LEVEL) is 0.
* initialize the pin level to 0 (default value) and update
the register value accordingly.
Second anf third patches:
* provide support to configure the pin output (i.e. PWM_PIN_LEVEL bit)
when the PWM is disabled.
* Follow this URL to access the discussion for version 1 of this
