From b305dbc08b08ab6681bfae8d33adc4f90fd3b9ad Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Wed, 28 Oct 2020 10:49:07 +0100 Subject: [PATCH] pinctrl: stm32: display bias information for all pins Display the bias information for input gpios or AF configuration, and not only for output pin, as described in Reference manual (Table 81. Port bit configuration table).
