Subject: [PATCH 05/11] drm/bridge: analogix-anx78xx: correct value of TX_P0
Date: Wed, 14 Aug 2019 20:48:48 -0400 [thread overview]
Message-ID: <20190815004854.19860-6-masneyb@onstation.org> (raw)
In-Reply-To: <20190815004854.19860-1-masneyb@onstation.org>
When attempting to configure this driver on a Nexus 5 phone (msm8974),
setting up the dummy i2c bus for TX_P0 would fail due to an -EBUSY
error. The downstream MSM kernel sources [1] shows that the proper value
for TX_P0 is 0x78, not 0x70, so correct the value to allow device
probing to succeed.
