# This is a list of all recognized I2C and ISA chips.
# Each entry must have the following fields:
#  name: The full chip name
#  driver: The driver name. Put in exactly:
#      * "to-be-written" if it is not yet available
#      * "use-isa-instead" if no i2c driver will be written
#  i2c_addrs (optional): For I2C chips, the list of I2C addresses to
#      probe.
#  i2c_detect (optional): For I2C chips, the function to call to detect
#      this chip. The function will be passed two parameters: an open file
#      descriptor to access the bus, and the I2C address to probe.
#  isa_addrs (optional): For ISA chips, the list of port addresses to
#      probe.
#  isa_detect (optional): For ISA chips, the function to call to detect
#      this chip. The function will be passed one parameter: the ISA address
#      to probe.
#  alias_detect (optional): For chips which can be both on the ISA and the
#      I2C bus, a function which detects whether two entries are the same.
#      The function will be passed three parameters: the ISA address, an
#      open file descriptor to access the I2C bus, and the I2C address.

#  driver: The driver name. Put in exactly:
#      * "to-be-written" if it is not yet available
#      * "not-a-sensor" if the chip doesn't have hardware monitoring
#	 capabilities (listing such chips here removes the need of manual
#	 lookup when people report them)
#      * "via-smbus-only" if this is a Super-I/O chip whose hardware
#	 monitoring registers can only be accessed via the SMBus
#  devid: The device ID we have to match (base device)
#  devid_mask (optional): Bitmask to apply before checking the device ID
#  regs (optional): Register definitions, where they differ from the standard.
#  logdev: The logical device containing the sensors
#  check (optional): A function to refine the detection. Will be passed
#      the index and data ports as parameters. Must return 1 for a matching
#      device, 0 otherwise.
#  features (optional): Features supported by this device, amongst:
#      * FEAT_IN
#      * FEAT_FAN
#      * FEAT_TEMP
