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.

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.
