* drivers/w1/masters/w1-gpio.c: use dev_get_platdata()Jingoo Han2013-11-151-5/+5
| | | | | | | | | | | | Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. This is a cosmetic change to make the code simpler and enhance the readability.

* drivers: w1: make w1_slave::flags long to avoid memory corruptionMichal Nazarewicz2013-11-132-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On architectures where long is more then 32 bits, modifying a 32-bit field with set_bit (and other atomic bit operations) may cause bytes following the field to by modified. Because the endianness of the bits within a field is the native endianness of the CPU[1], on big-endian machines, bit number zero is in the last byte of the field. Therefore, `set_bit(0, ptr)' on a 64-bit big-endian machine is roughly equivalent to `((char *)ptr)[7] |= 1', and since w1 driver uses a 32-bit field for holding the flags, this causes bytes beyond the field to be modified. [1] From Documentation/atomic_ops.txt: Native atomic bit operations are defined to operate on objects aligned to the size of an "unsigned long" C data type, and are least of that size. The endianness of the bits within each "unsigned long" are the native endianness of the cpu.

| | | | | | | | | | | | | | | | | | | | | | | | | | request_module for w1 slave modules needs to be called with the w1 master mutex unlocked. Because w1_attach_slave_device gets always(?) called with mutex locked, we need to temporarily unlock the w1 master mutex for the loading of the w1 slave module.

* drivers/w1/slaves/w1_ds2408.c: add magic sequence to disable P0 test modeJean-Francois Dagenais2013-07-041-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | Power-up timing The DS2408 is sensitive to the power-on slew rate and can inadvertently power up with a test mode feature enabled. When this occurs, the P0 port does not respond to the Channel Access Write command. For most reliable operation, it is recommended to disable the test mode after every power-on reset using the Disable Test Mode sequence shown below. The 64-bit ROM code must be transmitted in the same bit sequence as with the Match ROM command, i.e., least significant bit first. This precaution is recommended in parasite power mode (VCC pin connected to GND) as well as with VCC power.

I was too lazy to bisect for bad commit;) Reading the code I found problematic kthread_should_stop call from netlink connector which causes the oops. After applying a patch, I've been testing owfs+w1 setup for nearly two days and it seems to work very reliable (no hangs, no memleaks etc). More detailed description and possible fix is given below: Function w1_search can be called from either kthread or netlink callback. While the former works fine, the latter causes oops due to kthread_should_stop invocation. This patch adds a check if w1_search is serving netlink command, skipping kthread_should_stop invocation if so.

The base patch of the branch changes the format of the dts files to a slightly different format that makes it easier to do derivative board definitions, but it also introduces a lot of churn in the process since every line of the file is touched. On top of that are a handful of the regular changes; enabling more boards as DT-based instead of legacy board files (mx25pdk), enabling another driver for devicetree and thus adding bindings (onewire), etc. I'm not happy about the churn, and will likely not take it for other platforms in the future." * tag 'late-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (21 commits) ARM: dts: add dtsi for imx6q and imx6dl ARM: dts: rename imx6q.dtsi to imx6qdl.dtsi ARM: dts: i.MX6: Add regulator delay support ARM: dts: Add device tree entry for onewire master on i.MX53 ARM: i.MX53: Add clocks for i.mx53 onewire master.
