From 2817775556f6b3a88f5709f4e7fc0497a3cbba4d Mon Sep 17 00:00:00 2001 From: Jean-Jacques Hiblot Date: Wed, 17 Mar 2021 16:27:52 +0000 Subject: [PATCH] arm: dts: k3-am654: Enable access to I2C expander in SPL The am65x evm supports several daughter boards, the presence of which is detected by reading the state of a GPIO of a I2C gpio expander. To detect the daughter in the SPL, we need to enable the support for this GPIO expander.
