The pwm subsystem consist of API for PWM controllers, pwmbus to register them and a pwm(8) utility to talk to them from userland. Reviewed by: oshgobo (capsicum), bcr (manpage), 0mp (manpage) Differential Revision: https://reviews.freebsd.org/D17938 r342004 by manu: arm64: allwinner: Add pwm driver Add a pwm driver for Allwinner PWM Add pwm and aw_pwm to the GENERIC kernel r342005 by manu: arm64: allwinner: Add DTSO for pwm and r_pwm Those are both dtso (overlays) for the two pwm controllers found on the A64. r342006 by manu: arm64: allwinner: Fix pwm dtso Double patched files ended up in the tree Reported by: kevans r342007 by manu: pwm: Fix some arches by using %ju and casting to uintmax_t Reported by: ci.freebsd.org r342087 by manu: pwm: Convert period and duty to unsigned int We don't need a 64 bits value to store nanoseconds Discused with: ian, jhibbits r342088 by manu: pwm(8): Add percentage value support for duty cycle r342091 by manu: allwinner: aw_pwm: Read value at attach The booloaded might have configured the pwm controller so read the values.
