/*defination for meson pwm channel index
|
|
* for example:
|
|
* 1.there are four pwm controllers for axg:
|
|
* pwm A/B ,pwm C/D, pwm AOA/AOB, pwm AOC/AOD.
|
|
* each controller has four pwm channels:
|
|
* MESON_PWM_0,MESON_PWM_1,MESON_PWM_2,MESON_PWM_3
|
|
* when double pwm channels used, pwm channel
|
|
* [ MESON_PWM_0 and MESON_PWM_2 ],
|
|
* [ MESON_PWM_1 and MESON_PWM_3 ],
|
|
* should be used together.
|
|
*
|
|
* 2.there are two three pwm controllers for m8b:
|
|
* pwm A/B,pwm C/D,pwm E/F.
|
|
* each controller has two pwm channels:
|
|
* MESON_PWM_0 and MESON_PWM_1.
