====================
mlxsw: Introduce support for I2C bus
Vadim says:
This patchset adds I2C access support for SwitchX, SwitchX2, SwitchIB,
SwitchIB2 and Spectrum silicones.
It contains:
- Small changes in mlxsw core code, needed for I2C bus support;
- I2C driver, which obtains I2C input/output mailboxes setting and
provides command interface implementation.
- Minimal driver, which works on top of I2C driver and allows running
of mlxsw command interface over I2C bus;
Use case:
On system, which does not have PCI to ASIC (BMC), hwmon functionality
(sensors, pwm, tacho) will be available through I2C.
Usage (manual probing):
echo mlxsw_minimal 0x48 > /sys/bus/i2c/devices/i2c-2/new_device
Sysfs interface:
/sys/bus/i2c/devices/2-0048/hwmon/hwmon5/pwm1
/sys/bus/i2c/devices/2-0048/hwmon/hwmon5/temp1_input
