to assist you with patch sorting:

# revisions < v6 of "Convert period and duty cycle to u64"
pwclient -s Superseded 1237020 1237019 1229049 1229050 1222396

# most of "Add support for Azoteq IQS620A/621/622/624/625" v5 isn't for pwm

# "backlight: pwm_bl: Use gpiod_get_value_cansleep() to get initial

(Not sure "Rejected" is the right state.)
