Subject: [PULL 08/14] arm/aspeed: rainier: Add i2c eeproms and muxes
Date: Mon, 20 Sep 2021 10:09:22 +0200 [thread overview]
Message-ID: <20210920080928.1055567-9-clg@kaod.org> (raw)
In-Reply-To: <20210920080928.1055567-1-clg@kaod.org>
From: Joel Stanley <joel@jms.id.au>
These are the devices documented by the Rainier device tree. With this
we can see the guest discovering the multiplexers and probing the eeprom
devices:
i2c i2c-2: Added multiplexed i2c bus 16
i2c i2c-2: Added multiplexed i2c bus 17
i2c i2c-2: Added multiplexed i2c bus 18
i2c i2c-2: Added multiplexed i2c bus 19
i2c-mux-gpio i2cmux: 4 port mux on 1e78a180.i2c-bus adapter
at24 20-0050: 8192 byte 24c64 EEPROM, writable, 1 bytes/write
i2c i2c-4: Added multiplexed i2c bus 20
at24 21-0051: 8192 byte 24c64 EEPROM, writable, 1 bytes/write
i2c i2c-4: Added multiplexed i2c bus 21
at24 22-0052: 8192 byte 24c64 EEPROM, writable, 1 bytes/write
