From 9ca8dbcc65cfc63d6f5ef3312a33184e1d726e00 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Tue, 4 Aug 2015 12:17:53 -0700 Subject: Add the rt linux 4.1.3-rt3 as base Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior We lose all the git history this way and it's not good. We should apply another opnfv project repo in future.

Please see +Documentation/hwmon/pmbus and Documentation.hwmon/pmbus-core for details +on PMBus client drivers. + + +Usage Notes +----------- + +This driver does not auto-detect devices. You will have to instantiate the +devices explicitly. Please see Documentation/i2c/instantiating-devices for +details. + +WARNING: Do not access chip registers using the i2cdump command, and do not use +any of the i2ctools commands on a command register used to save and restore +configuration data (0x11, 0x12, 0x15, 0x16, and 0xf4). The chips supported by +this driver interpret any access to those command registers (including read +commands) as request to execute the command in question. Unless write accesses +to those registers are protected, this may result in power loss, board resets, +and/or Flash corruption. Worst case, your board may turn into a brick. + + +Platform data support +--------------------- + +The driver supports standard PMBus driver platform data. + + +Module parameters +----------------- + +delay +----- + +Intersil/Zilker Labs DC-DC controllers require a minimum interval between I2C +bus accesses. According to Intersil, the minimum interval is 2 ms, though 1 ms +appears to be sufficient and has not caused any problems in testing. The problem +is known to affect all currently supported chips. For manual override, the +driver provides a writeable module parameter, 'delay', which can be used to set +the interval to a value between 0 and 65,535 microseconds. + + +Sysfs entries +------------- + +The following attributes are supported. Limits are read-write; all other +attributes are read-only. + +in1_label "vin" +in1_input Measured input voltage. +in1_min Minimum input voltage. +in1_max Maximum input voltage. +in1_lcrit Critical minimum input voltage. +in1_crit Critical maximum input voltage. +in1_min_alarm Input voltage low alarm. +in1_max_alarm Input voltage high alarm. +in1_lcrit_alarm Input voltage critical low alarm. +in1_crit_alarm Input voltage critical high alarm. + +in2_label "vmon" +in2_input Measured voltage on VMON (ZL2004) or VDRV (ZL9101M, + ZL9117M) pin.
