drivers: w1: Add 1w slave driver for DS28E05 EEPROM

2017-08-28T15:23:29Z

Add a one wire driver for the DS28E05 one wire slave chip. This chip requires OverDrive support to talk to it. Signed-off-by: Andrew Worsley Acked-by: Evgeniy Polyakov Signed-off-by: Greg Kroah-Hartman

w1: constify attribute_group structures.

2017-08-28T15:15:16Z

attribute_group are not supposed to change at runtime. All functions working with attribute_group provided by work with const attribute_group. So mark the non-const structs as const. Signed-off-by: Arvind Yadav Signed-off-by: Greg Kroah-Hartman

w1: Fix slave count on 1-Wire bus (resend)

2017-07-17T14:45:16Z

1-Wire bus have very fast algorith for exchange with single slave device. Fix incorrect count of slave devices on connect second slave device. This case on slave device probe() step we need use generic (multislave) functions for read/write device. Signed-off-by: Alex A. Mihaylov Acked-by: Evgeniy Polyakov Signed-off-by: Greg Kroah-Hartman

w1: Add subsystem kernel public interface

2017-06-09T09:54:54Z

Like other subsystems we should be able to define slave devices outside of the w1 directory. To do this we move public facing interface definitions to include/linux/w1.h and rename the internal definition file to w1_internal.h. As w1_family.h and w1_int.h contained almost entirely public driver interface definitions we simply removed these files and moved the remaining definitions into w1_internal.h. With this we can now start to move slave devices out of w1/slaves and into the subsystem based on the function they implement, again like other drivers. Signed-off-by: Andrew F.

w1: Organize driver source to natural/common order

2017-05-25T16:23:03Z

Structures and functions should be ordered such that forward declaration use is minimized. MODULE_* macros should immediately follow the structures and functions upon which they act. Remaining MODULE_* macros should be at the end of the file in alphabetical order. Signed-off-by: Andrew F. Davis Acked-by: Evgeniy Polyakov Signed-off-by: Greg Kroah-Hartman

w1: Remove unneeded use of assert() and remove w1_log.h

2017-04-08T16:20:57Z

The only use of assert() is in matrox_w1.c and is used to check the input to probe() from the PCI subsystem for NULL values, these are guaranteed to be populated and no other PCI driver makes this check, remove this. As this was the only definition in w1_log.h, remove this also. Signed-off-by: Andrew F. Davis Signed-off-by: Greg Kroah-Hartman

w1: Fixup source file headers

2017-01-25T10:48:03Z

Remove filename from file, this is not done anymore as it doesn't add anything and usually is incorrect as filename change often. Also shorten the GPL to the more common address-less version and remove excess white-space. Signed-off-by: Andrew F. Davis Signed-off-by: Greg Kroah-Hartman

w1: don't leak refcount on slave attach failure in w1_attach_slave_device()

2017-01-25T10:46:42Z

Near the beginning of w1_attach_slave_device() we increment a w1 master reference count. Later, when we are going to exit this function without actually attaching a slave device (due to failure of __w1_attach_slave_device()) we need to decrement this reference count back.
