Subject: [PATCH 5/5] ARM: tegra: nyan-blaze: Proper pinmux for TPM i2c
Date: Sun, 22 Jan 2017 15:44:15 +0100 [thread overview]
Message-ID: <20170122144415.31208-5-contact@paulk.fr> (raw)
In-Reply-To: <20170122144415.31208-1-contact@paulk.fr>
From: Jerome Coste <jerome.coste@etu.utc.fr>
This corrects the pinmux for accessing the TPM over the i2c line.
Thus, it allows correctly probing the module, that previously failed with i2c
errors.
