Subject: [PATCH 1/3] arm64: dts: ti: k3-am625-phyboard-lyra-rdk: Lower I2C1 frequency
Date: Mon, 4 Dec 2023 14:28:09 -0800 [thread overview]
Message-ID: <20231204222811.2344460-1-ggiordano@phytec.com> (raw)
The gpio-expander on i2c-1 has a maximum frequency of 100kHz. Update our
main_i2c1 frequency to allow the nxp,pcf8574 gpio-expander to function
properly.
