Subject: [PATCH v3 06/15] phy: qcom-qmp-combo: drop redundant clock structure
Date: Mon, 21 Nov 2022 09:50:49 +0100	[thread overview]
Message-ID: <20221121085058.31213-7-johan+linaro@kernel.org> (raw)
In-Reply-To: <20221121085058.31213-1-johan+linaro@kernel.org>

Drop the unnecessary DP clock structure and instead store the clocks
directly in the driver data.

Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
