Subject: [PATCH] mediatek: Set default value for Panel Orientation connector prop.
Date: Fri, 22 Oct 2021 13:24:03 -0400	[thread overview]
Message-ID: <20211022172413.195559-1-markyacoub@chromium.org> (raw)

From: Mark Yacoub <markyacoub@google.com>

[Why]
Creating the prop uses UNKNOWN as the initial value, which is not a
supported value if the props is to be supported.

[How]
Set the panel orientation default value to NORMAL right after creating
the prop.

Tested on Jacuzzi(MTK)
Fixes IGT@kms_properties@get_properties-sanity-{atomic,non-atomic}
