I've sent this patchset first to the linux-i2c mailing list, but I was told to better send it to the lm-sensors list as more interested people might find it here. -- This is an attempt to upstream the patches created by Thomas Brandon and Eddi De Pieri to support the multiplexed main SMBus interface on the SB800 chipset. (https://www.mail-archive.com/linux-i2c@xxxxxxxxxxxxxxx/msg06757.html) I have mainly rebased the latest patch version and tested the driver on a HP ProLiant MicroServer G7 N54L (where this patch allows to access sensor data from a w83795adg). The patched driver is running stable on the machine, given that ic2_piix4 is loaded before jc42 and w83795. If jc42 is loaded before i2c_piix4 calling sensors triggers some errors: ERROR: Can't get value of subfeature temp1_min_alarm: Can't read While the kernel log shows: i2c i2c-1: Transaction (pre): CNT=0c, CMD=05, ADD=31, DAT0=03, DAT1=c0 i2c i2c-1: Error: no response! i2c i2c-1: Transaction (post): CNT=0c, CMD=05, ADD=31, DAT0=ff, DAT1=ff Unfortunately I don't know how to tackle this specific issue. Please review and let me know required changes in order to get this upstream finally. Eddi, Thomas, it would be great if you could verify the changes on your machines. Regards, Christian Christian Fetzer (4): i2c-piix4: Optionally release smba in piix4_adap_remove i2c-piix4: Convert piix4_main_adapter to array i2c-piix4: Add support for multiplexed main adapter in SB800 i2c-piix4: Add adapter port name support for SB800 chipset drivers/i2c/busses/i2c-piix4.c | 151 ++++++++++++++++++++++++++++++++++++----- 1 file changed, 134 insertions(+), 17 deletions(-) -- 1.9.1 _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
