Subject: [PATCH v4 23/24] drm/msm/dsi: inline msm_dsi_phy_set_src_pll
Date: Wed, 31 Mar 2021 13:57:34 +0300	[thread overview]
Message-ID: <20210331105735.3690009-24-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20210331105735.3690009-1-dmitry.baryshkov@linaro.org>

The src_truthtable config is not used for some of phys, which use other
means of configuring the master/slave usecases. Inline this function
with the goal of removing src_pll_id argument in the next commit.
