Subject: [PATCH v3 1/2] drm/msm: add compatibles for sm8150/sm8250 display
Date:   Mon, 15 Feb 2021 11:26:04 -0500
Message-Id: <20210215162607.21360-2-jonathan@marek.ca>
In-Reply-To: <20210215162607.21360-1-jonathan@marek.ca>
References: <20210215162607.21360-1-jonathan@marek.ca>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

The driver already has support for sm8150/sm8250, but the compatibles were
never added.

Also inverse the non-mdp4 condition in add_display_components() to avoid
having to check every new compatible in the condition.
