H A D | i2c-mux-gpio.yaml | diff dc53dbe3e79008ca7c1bc5e5ae2c71b52161f96d Mon Jun 17 14:08:16 CEST 2024 Bastien Curutchet <bastien.curutchet@bootlin.com> dt-bindings: i2c: mux-gpio: Add 'settle-time-us' property
I2C MUXes described by the i2c-gpio-mux sometimes need a significant amount of time to switch from a bus to another. When a new bus is selected, the first I2C transfer can fail if it occurs too early. There is no way to describe this transition delay that has to be waited before starting the first I2C transfer.
Add a 'settle-time-us' property that indicates the delay to be respected before doing the first i2c transfer.
