Subject: [PATCH v4 06/11] drm/msm/dsi/phy: rework register setting for 7nm PHY
Date: Wed, 23 Nov 2022 01:12:29 +0200	[thread overview]
Message-ID: <20221122231235.3299737-7-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20221122231235.3299737-1-dmitry.baryshkov@linaro.org>

In preparation to adding the sm8350 and sm8450 PHYs support, rearrange
register values calculations in dsi_7nm_phy_enable(). This change bears
no functional changes itself, it is merely a preparation for the next
patch.
