Kernel driver ltc4260 ===================== Supported chips: * Linear Technology LTC4260 Prefix: 'ltc4260' Addresses scanned: - Datasheet: http://cds.linear.com/docs/en/datasheet/4260fc.pdf Author: Guenter Roeck <linux@roeck-us.net> Description ----------- The LTC4260 Hot Swap controller allows a board to be safely inserted and removed from a live backplane. Usage Notes ----------- This driver does not probe for LTC4260 devices, since there is no register which can be safely used to identify the chip. You will have to instantiate the devices explicitly. Example: the following will load the driver for an LTC4260 at address 0x10 on I2C bus #1:: $ modprobe ltc4260 $ echo ltc4260 0x10 > /sys/bus/i2c/devices/i2c-1/new_device Sysfs entries ------------- Voltage readings provided by this driver are reported as obtained from the ADC registers. If a set of voltage divider resistors is installed, calculate the real voltage by multiplying the reported value with (R1+R2)/R2, where R1 is the value of the divider resistor against the measured voltage and R2 is the value of the divider resistor against Ground. Current reading provided by this driver is reported as obtained from the ADC Current Sense register. The reported value assumes that a 1 mOhm sense resistor is installed. If a different sense resistor is installed, calculate the real current by dividing the reported value by the sense resistor value in mOhm. ======================= ======================= in1_input SOURCE voltage (mV) in1_min_alarm Undervoltage alarm in1_max_alarm Overvoltage alarm in2_input ADIN voltage (mV) in2_alarm Power bad alarm curr1_input SENSE current (mA) curr1_alarm SENSE overcurrent alarm ======================= ======================= |
