As far as I know it is going somewhere, but it's not moving terribly
quickly.  At some point I think Boris got tired of posting huge patch
sets and so split things in two.  The first half did eventually land,
but the second half is still outstanding and things seem quiet fro the
last two weeks.  From patchwork we have these outstanding:

9175319  [v3,01/14] pwm: Add an helper to prepare a new PWM state
9175345  [v3,02/14] pwm: Add two helpers to ease relative duty cycle ...
9175361  [v3,03/14] pwm: rockchip: Fix period and duty_cycle approximation
9175341  [v3,04/14] pwm: rockchip: Add support for hardware readout
9175335  [v3,05/14] pwm: rockchip: Avoid glitches on already running PWMs
