From mboxrd@z Thu Jan 1 00:00:00 1970 From: Delphine CC Chiu Date: Thu, 3 Oct 2024 15:42:43 +0800 Subject: [PATCH v3 2/9] ARM: dts: aspeed: yosemite4: Add i2c-mux for four NICs In-Reply-To: <20241003074251.3818101-1-Delphine_CC_Chiu@wiwynn.com> References: <20241003074251.3818101-1-Delphine_CC_Chiu@wiwynn.com> Message-ID: <20241003074251.3818101-3-Delphine_CC_Chiu@wiwynn.com> List-Id: To: linux-aspeed@lists.ozlabs.org MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit From: Ricky CX Wu Add i2c-mux on Spider board for four NICs and add the temperature sensor and EEPROM for the NICs. Also remove the mctp-controller property on I2C bus 15 because we need to add the property on the I2C mux to each NIC so that the MCTP driver will ensure that each port is configured properly before communicating with the NICs.
