Subject: [PATCH] pinctrl: single: config: enable the pin's input
Date: Fri, 14 May 2021 18:38:18 +0200 [thread overview]
Message-ID: <20210514163818.12178-1-dariobin@libero.it> (raw)
It enables / disables the input buffer. As explained in the description
of 'enum pin_config_param' this does not affect the pin's ability to
drive output.
