Most Keplers actually use the GPIO-based voltage management instead of the new PWM-based one. Use the GPIO mode as a fallback as it already gracefully handles the case where no GPIOs exist. All the Maxwells seem to use the PWM method though. v2: - Do not forget to commit the PWM configuration change! Signed-off-by: Martin Peres <martin.peres@free.fr>
