1 Kernel driver tps40422 2 ====================== 3 4 Supported chips: 5 * TI TPS40422 6 Prefix: 'tps40422' 7 Addresses scanned: - 8 Datasheet: http://www.ti.com/lit/gpn/tps40422 9 10 Author: Zhu Laiwen <richard.zhu@nsn.com> 11 12 13 Description 14 ----------- 15 16 This driver supports TI TPS40422 Dual-Output or Two-Phase Synchronous Buck 17 Controller with PMBus 18 19 The driver is a client driver to the core PMBus driver. 20 Please see Documentation/hwmon/pmbus for details on PMBus client drivers. 21 22 23 Usage Notes 24 ----------- 25 26 This driver does not auto-detect devices. You will have to instantiate the 27 devices explicitly. Please see Documentation/i2c/instantiating-devices for 28 details. 29 30 31 Platform data support 32 --------------------- 33 34 The driver supports standard PMBus driver platform data. 35 36 37 Sysfs entries 38 ------------- 39 40 The following attributes are supported. 41 42 in[1-2]_label "vout[1-2]" 43 in[1-2]_input Measured voltage. From READ_VOUT register. 44 in[1-2]_alarm voltage alarm. 45 46 curr[1-2]_input Measured current. From READ_IOUT register. 47 curr[1-2]_label "iout[1-2]" 48 curr1_max Maximum current. From IOUT_OC_WARN_LIMIT register. 49 curr1_crit Critical maximum current. From IOUT_OC_FAULT_LIMIT register. 50 curr1_max_alarm Current high alarm. From IOUT_OC_WARN_LIMIT status. 51 curr1_crit_alarm Current critical high alarm. From IOUT_OC_FAULT status. 52 curr2_alarm Current high alarm. From IOUT_OC_WARNING status. 53 54 temp1_input Measured temperature. From READ_TEMPERATURE_2 register on page 0. 55 temp1_max Maximum temperature. From OT_WARN_LIMIT register. 56 temp1_crit Critical high temperature. From OT_FAULT_LIMIT register. 57 temp1_max_alarm Chip temperature high alarm. Set by comparing 58 READ_TEMPERATURE_2 on page 0 with OT_WARN_LIMIT if TEMP_OT_WARNING 59 status is set. 60 temp1_crit_alarm Chip temperature critical high alarm. Set by comparing 61 READ_TEMPERATURE_2 on page 0 with OT_FAULT_LIMIT if TEMP_OT_FAULT 62 status is set. 63 temp2_input Measured temperature. From READ_TEMPERATURE_2 register on page 1. 64 temp2_alarm Chip temperature alarm on page 1.
