2009-06-18w1-gpio: add external pull-up enable callbackDaniel Mack
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.

2009-04-05mfd: remove DS1WM clock handlingPhilipp Zabel
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: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>

2009-03-12drivers/w1/masters/w1-gpio.c: fix read_bit()Daniel Mack
W1 master implementations are expected to return 0 or 1 from their read_bit() function. However, not all platforms do return these values from gpio_get_value() - namely PXAs won't. Hence the w1 gpio-master needs to break the result down to 0 or 1 itself.

2008-11-12hdq driver for OMAP2430/3430Madhusudhan Chikkature
The HDQ/1-Wire module of TI OMAP2430/3430 platforms implement the hardware protocol of the master functions of the Benchmark HDQ and the Dallas Semiconductor 1-Wire protocols. These protocols use a single wire for communication between the master (HDQ/1-Wire controller) and the slave (HDQ/1-Wire external compliant device). This patch provides the HDQ driver to suppport TI OMAP2430/3430 platforms.

2008-10-16W1: ds2490.c optimize ds_set_pullupDavid Fries
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.

2008-10-16W1: ds2490.c reset ds2490 in initDavid Fries
Reset the device in init as it can be in a bad state. This is necessary because a block write will wait for data to be placed in the output buffer and block any later commands which will keep accumulating and the device will not be idle. Another case is removing the ds2490 module while a bus search is in progress, somehow a few commands get through, but the input transfers fail leaving data in the input buffer. This will cause the next read to fail see the note in ds_recv_data.

2008-10-16W1: ds2490.c simplify and fix ds_touch_bitDavid Fries
Simplify and fix ds_touch_bit. If a device is attached in the middle of a bus search the status register will return more than the default 16 bytes. The additional bytes indicate that it has detected a new device. The way ds_wait_status is coded, if it doesn't read 16 status bytes it returns an error value. ds_touch_bit then will detect that error and return an error. In that case it doesn't read the input buffer and returns uninitialized data. It doesn't stop there. The next transaction will not expect the extra byte in the input buffer and the short read will cause an error and clear out both the old byte and new data in the input buffer. Just ignore the value of ds_wait_status. It is still required to wait until ds2490 is again idle and there is data to read when ds_recv_data is called. This also removes the while loop. None of the other commands wait and verify that the issued command is in the status register.

Don't export read and write bit operations, they didn't work, they weren't used, and they can't be made to work.

2008-10-16W1: ds2490.c add support for strong pullupDavid Fries
Add strong pullup support for ds2490 driver, also drop mdelay(750), which busy waits, usage in favour of msleep for long delays. Now with msleep only being called when the strong pullup is active, one wire bus operations are only taking minimal system overhead. The new set_pullup will only enable the strong pullup when requested, which is expected to be the only write operation that will benefit from a strong pullup.

2008-10-16W1: ds1wm.c msleep for resetDavid Fries
Like the previous w1_io.c reset coments and msleep patch, I don't have the hardware to verify the change, but I think it is safe. It also helps to see a comment like this in the code. "We'll wait a bit longer just to be sure." If they are going to calculate delaying 324.9us, but actually delay 500us, why not just give up the CPU and sleep? This is designed for a battery powered ARM system, avoiding busywaiting has to be good for battery life. I sent a request for testers March 7, 2008 to the Linux kernel mailing list and two developers who have patches for ds1wm.c, but I didn't get any respons.

2008-10-16W1: fix deadlocks and remove w1_control_threadDavid Fries
w1_control_thread was removed which would wake up every second and process newly registered family codes and complete some final cleanup for a removed master. Those routines were moved to the threads that were previously requesting those operations. A new function w1_reconnect_slaves takes care of reconnecting existing slave devices when a new family code is registered or removed. The removal case was missing and would cause a deadlock waiting for the family code reference count to decrease, which will now happen. A problem with registering a family code was fixed. A slave device would be unattached if it wasn't yet claimed, then attached at the end of the list, two unclaimed slaves would cause an infinite loop. The struct w1_bus_master.search now takes a pointer to the struct w1_master device to avoid searching for it, which would have caused a lock ordering deadlock with the removal of w1_control_thread.
