w1: select crc16 library for ds2406

2014-06-23T16:38:08Z

commit 94859308a21b "w1: new w1_ds2406 driver" added a new driver that uses the crc16 library, but didn't ensure that the core is there. This adds the necessary Kconfig statements, just like we have it for other w1 drivers.

w1/slaves: use pr_* instead of printk

2014-06-20T00:46:51Z

This patch replaces all calls to the "printk" function within the "slaves" subdirectory by calls to the appropriate "pr_*" function thus addressing the following warning generated by the checkpatch script: WARNING: Prefer [subsystem eg: netdev]_err([subsystem]dev, ... then dev_err(dev, ... then pr_err(... to printk(KERN_ERR ...

w1: new w1_ds2406 driver

2014-06-20T00:45:14Z

Some preliminary work at making use of this driver led me to implement CRC-16 checks on read and write to deal with the occasional glitchiness of the 1-Wire bus. The revised driver (attached) returns an I/O error if the CRC check fails. When reading the chip's state, either you get a valid indication or you get an I/O error. When changing its state, either the change is successful or an I/O error is returned. Signed-off-by: Scott Alfter Acked-by: Evgeniy Polyakov Signed-off-by: Greg Kroah-Hartman

w1: Remove excess dependencies on W1 for masters and slaves

2014-02-28T23:27:09Z

Configuration for masters and slaves is included only if W1 symbol enabled, so no reason to check it once more. Signed-off-by: Alexander Shiyan Signed-off-by: Greg Kroah-Hartman

w1: use family_data instead of rom in w1_slave

2014-02-07T23:40:18Z

The first line printed from w1_slave gives the context of the w1 device. So does the second line, but if the CRC check failed, the second line contains the last successful result. It is confusing when it prints the temperature next to the line that might be a previous conversion and has nothing to do with that printed temperature value. Modify the code to store the last good conversion in family_data, which is designed for custom data structures.

w1: slaves: w1_ds2781: convert to use w1_family_ops.groups

2013-08-22T18:05:44Z

This moves the sysfs file creation/removal to the w1 core by using the .groups field, saving code in the slave driver. Acked-by: Evgeniy Polyakov Cc: Alexander Stein Cc: Andrew Morton Cc: Wei Yongjun Signed-off-by: Greg Kroah-Hartman
