[PATCH v3 0/2] pwm: Introduce pwm driver for the Loongson family chips

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all:

This patchset introduce a generic PWM framework driver for Loongson family.
Each PWM has one pulse width output signal and one pulse input signal to be measured.

It can be found on Loongson-2K series cpus and Loongson LS7A bridge chips.

Thanks.
