  47. Description
  48. -----------
  49. This driver supports hardware montoring for Intersil / Zilker Labs ZL6100 and
  50. compatible digital DC-DC controllers.
  51. The driver is a client driver to the core PMBus driver. Please see
  52. Documentation/hwmon/pmbus and Documentation.hwmon/pmbus-core for details
  53. on PMBus client drivers.
  54. Usage Notes
  55. -----------
  56. This driver does not auto-detect devices. You will have to instantiate the
  57. devices explicitly. Please see Documentation/i2c/instantiating-devices for
  58. details.
  59. WARNING: Do not access chip registers using the i2cdump command, and do not use
  60. any of the i2ctools commands on a command register used to save and restore
  61. configuration data (0x11, 0x12, 0x15, 0x16, and 0xf4). The chips supported by
  62. this driver interpret any access to those command registers (including read
  63. commands) as request to execute the command in question. Unless write accesses
  64. to those registers are protected, this may result in power loss, board resets,
  65. and/or Flash corruption. Worst case, your board may turn into a brick.
  66. Platform data support
  67. ---------------------
  68. The driver supports standard PMBus driver platform data.
  69. Module parameters
  70. -----------------
  71. delay
  72. -----
  73. Intersil/Zilker Labs DC-DC controllers require a minimum interval between I2C
  74. bus accesses. According to Intersil, the minimum interval is 2 ms, though 1 ms
  75. appears to be sufficient and has not caused any problems in testing. The problem
  76. is known to affect all currently supported chips. For manual override, the
  77. driver provides a writeable module parameter, 'delay', which can be used to set
  78. the interval to a value between 0 and 65,535 microseconds.
  79. Sysfs entries
  80. -------------
  81. The following attributes are supported. Limits are read-write; all other
  82. attributes are read-only.
