From c269df8c5ad316eac47a9078e7a2339e1956637a Mon Sep 17 00:00:00 2001 From: Nuno Sá Date: Wed, 13 Jul 2022 15:14:18 +0200 Subject: gpiolib: add support for bias pull disable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This change prepares the gpio core to look at firmware flags and set 'FLAG_BIAS_DISABLE' if necessary. It works in similar way to 'GPIO_PULL_DOWN' and 'GPIO_PULL_UP'.
