Subject: [PATCH 5/7] arm64: dts: rockchip: add mule i2c mux (0x18) on rk3588-tiger
Date: Fri, 26 Apr 2024 18:49:36 +0200 [thread overview]
Message-ID: <20240426-dev-mule-i2c-mux-v1-5-045a482f6ffb@theobroma-systems.com> (raw)
In-Reply-To: <20240426-dev-mule-i2c-mux-v1-0-045a482f6ffb@theobroma-systems.com>
Mule emulates an i2c mux (address 0x18). The amc6821 is exposed behind
this bus.
Add the mux node and amc6821 as a default device.
