Subject[PATCH 5.10 560/599] pinctrl: pinconf-generic: Print arguments for bias-pull-*
From: Chen-Yu Tsai <>

commit 188e5834b930acd03ad3cf7c5e7aa24db9665a29 upstream.

The bias-pull-* properties, or PIN_CONFIG_BIAS_PULL_* pin config
parameters, accept optional arguments in ohms denoting the strength of
the pin bias.

Print these values out in debugfs as well.

Fixes: eec450713e5c ("pinctrl: pinconf-generic: Add flag to print arguments")
