A pointer to omap_hdq_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

There is no point in implementing a detect callback for the DS2482, as this device can't be detected. It was there solely to handle "force" module parameters to instantiate devices, but now we have a better sysfs interface that can do the same. So we can get rid of the ugly module parameters and the detect callback. This shrinks the binary module size by 21%.

The connector documentation states that the argument to the callback function is always a pointer to a struct cn_msg, but rather than encode it in the API itself, it uses a void pointer everywhere. This doesn't make much sense to encode the pointer in documentation as it prevents proper C type checking from occurring and can easily allow people to use the wrong pointer type. So convert the argument type to an explicit struct cn_msg pointer. Signed-off-by: NMike Frysinger <vapier@gentoo.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

On embedded devices, sleep mode conditions can be tricky to handle, Especially when processors tend to pull-down the w1 bus during sleep. Bus slaves (such as the ds2760) may interpret this as a reason for power-down conditions and entirely switch off the device. This patch adds a callback function pointer to let users switch on and off the external pull-up resistor. This lets the outside world know whether the processor is currently actively driving the bus or not. When this callback is not provided, the code behaviour won't change.

This adds support for ds2760's sleep mode feature. With this feature enabled, the chip enters a deep sleep mode and disconnects from the battery when the w1 line is held down for more than 2 seconds.

This driver requests a clock that usually is supplied by the MFD in which the DS1WM is contained. Currently, it is impossible for a MFD to register their clocks with the generic clock API due to different implementations across architectures. For now, this patch removes the clock handling from DS1WM altogether, trusting that the MFD enable/disable functions will switch the clock if needed. The clock rate is obtained from a new parameter in driver_data. Signed-off-by: NPhilipp Zabel <philipp.zabel@gmail.com> Signed-off-by: NSamuel Ortiz <sameo@openedhand.com>

This small patchset extendes existing commands with reset, master IO and status messages. Reset is used to reset the bus for given master device, master IO command allows to initiate IO against bus itself not selecting slave device first, which can be used to probe the device for example. And status messages carry command completion status back to the userspace (namely very useful to get -ENODEV from when requested device was not found). Great thanks to Paul Alfille of OWFS for testing and commands suggestions. This patch: Allow starting of IO not against already found slave devices, but against the bus itself, which can be used for example to probe devices.

Tejun's commit 7b595756 made sysfs attribute->owner unnecessary. But the field was left in the structure to ease the merge. It's been over a year since that change and it is now time to start killing attribute->owner along with its users - one arch at a time! This patch is attempt #1 to get rid of attribute->owner only for CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on as and when possible - avr32 will be the next since that is something I can test. Compile (make allyesconfig / make allmodconfig / custom config) and boot tested. akpm: the idea is that we put the declaration of sttribute.owner inside `#ifndef CONFIG_X86'. But that proved to be too ambitious for now because new usages kept on turning up in subsystem trees.

Optimize the ds_set_pullup function. For a strong pullup to be sent the ds2490 has to have both the strong pullup mode enabled, and the specific write operation has to have the SPU bit enabled. Previously the write always had the SPU bit enabled and both the duration and model was set when a strong pullup was requested. Now the strong pullup mode is enabled at initialization time, the delay is updated only when the value changes, and the write SPU bit is set only when a strong pullup is required. This removes two or three bus transactions per strong pullup request.
