Subject: [PATCH 12/17] phy: qcom-qmp-pcie: consolidate lane config
Date: Tue, 20 Sep 2022 09:38:21 +0200	[thread overview]
Message-ID: <20220920073826.20811-13-johan+linaro@kernel.org> (raw)
In-Reply-To: <20220920073826.20811-1-johan+linaro@kernel.org>

For legacy reasons, there are two configuration parameters that describe
the number of lanes a PHY has.

Replace them both with a new field simply named "lanes".
