From 019090647cab4eb0e9a3ab99e64adde3b65e631e Mon Sep 17 00:00:00 2001 From: =?utf8?q?Pali=20Roh=C3=A1r?= Date: Thu, 4 Aug 2022 12:41:56 +0200 Subject: [PATCH] arm64: a37xx: pinctrl: Improve description for pinmux command MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In more cases group name consist of function name followed by function number. So if function name is just prefix of group name, show group name. So in 'pinmux status -a' command output would be visible also extended function number, which is useful for debugging.
