Subject: [PATCH 4.9 153/218] pinctrl: pinconf-generic: Print arguments for bias-pull-*
From: Chen-Yu Tsai <wenst@...omium.org>
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")
