Subject: [PATCH v6 03/10] drm: bridge: samsung-dsim: Mark PHY as optional
Date: Sat, 1 Oct 2022 13:36:43 +0530 [thread overview]
Message-ID: <20221001080650.1007043-4-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20221001080650.1007043-1-jagan@amarulasolutions.com>
In i.MX8M Mini/Nano SoC the DSI Phy requires a MIPI DPHY bit
to reset in order to activate the PHY and that can be done via
upstream i.MX8M blk-ctrl driver.
So, mark the phy get as optional.
v6, v5, v4, v3, v2:
* none
v1:
* new patch
