From 928af2247785f7a1aec21e82a3ceba7c0c85f593 Mon Sep 17 00:00:00 2001 From: Niklas Cassel Date: Thu, 22 Feb 2018 16:22:47 +0100 Subject: [PATCH] pinctrl: artpec6: dt: add smaller groups for uarts Add group configuration for uarts that are cut down variants, the standard being full, i.e. all signals, flow control, i.e. rx/tx and cts/rts, and rx/tx only. This allows us to be more precise in which pins we're actually using. Unfortunately the existing naming scheme leaves things to be desired, e.g. uart3grp0 means RX/TX and CTS/RTS, yet uart0grp0 means all pins. Since the exising suffixes have different meaning for different uarts, and the fact that we cannot change the name of existing groups, makes it hard to use a descriptive name for the newly added groups.
