I'm curious what SoC are you using?

I'm working on Amazon Annapurna Labs SoCs (based on ARM cortex processors). That include multiple pins controlled with same register.


It's good to know who has hardware to test bits_per_mux in the future.

I pay attention to pinctrl-single as that is the driver used for the TI
AM3358 SoC used in a variety of BeagleBone boards.  It does not use
bits_per_mux, but I can verify that this does not cause any regression
for the AM3358 SoC:

   /sys/kernel/debug/pinctrl/44e10800.pinmux-pinctrl-single# cat pins
   registered pins: 142
   pin 0 (PIN0) 0:? 44e10800 00000027 pinctrl-single
