Subject: [PATCH v5 1/4] ASoC: Intel: sof_es8336: simplify speaker gpio naming
Date:   Thu,  7 Apr 2022 20:49:56 +0200
Message-Id: <3008c576ca45d5cc99ad4a18d1d30de45a0aff80.1649357263.git.mchehab@kernel.org>

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

In preparation for the support of an additional gpio for headphone
control, rename GPIOs to make explicit references to speakers and
gpio0 or gpio1.

No functionality change.
