Subject: [U-Boot] [PATCH v3 08/18] arm64: dts: k3-am654-base-board: Add I2C GPIO expander @ 0x38
Date: Tue, 4 Jun 2019 18:08:18 -0500 [thread overview]
Message-ID: <20190604230828.12539-9-dannenberg@ti.com> (raw)
In-Reply-To: <20190604230828.12539-1-dannenberg@ti.com>
The AM654 base board has a TCA9554/PCA9554-type GPIO expander on the
wkup_i2c0 bus at address 0x38 that is used to detect the presence of
daughter cards. Add a respective DTS description of this expander
to enable its use.
