Subject: [PATCH v4 10/24] drm/msm/dsi: push provided clocks handling into a generic code
Date: Wed, 31 Mar 2021 13:57:21 +0300	[thread overview]
Message-ID: <20210331105735.3690009-11-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20210331105735.3690009-1-dmitry.baryshkov@linaro.org>

All MSM DSI PHYs provide two clocks: byte and pixel ones.
Register/unregister provided clocks from the generic place, removing
boilerplate code from all MSM DSI PHY drivers.
