From 9b884e79a6ac8cededabc3eced318d212a9c8fc3 Mon Sep 17 00:00:00 2001 From: Dario Binacchi Date: Sun, 11 Apr 2021 09:39:41 +0200 Subject: [PATCH] pinctrl: single: fix offset management The pinmux configuration DT node of a peripheral does not define a physical address but an offset. Only by adding it to the base address of the controller it is possible to calculate the physical address of the register to be configured. Printing an offset also requires a different formatting option than a physical address.
