This patchs adds the CONFIG_AIO option which allows to remove support for asynchronous I/O operations, that are not necessarly used by applications, particularly on embedded devices. As this is a size-reduction option, it depends on CONFIG_EMBEDDED.

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. Signed-off-by:

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. Signed-off-by:

David Fries authored
- add result register #defines - rename ds_dump_status to ds_print_msg - rename ds_recv_status to ds_dump_status - ds_dump_status prints the requested status and no longer reads the status, this is because the second status read can return different data for example the result register - the result register will be printed, though limited to detecting a new device, detecting other values such as a short would require additional reporting methods - ST_EPOF was moved to ds_wait_status to clear the error condition sooner Signed-off-by:

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. Signed-off-by:

Don't export read and write bit operations, they didn't work, they weren't used, and they can't be made to work. The one wire low level bit operations expect to set high or low levels, the ds2490 hardware only supports complete read or write time slots, better to just comment them out. Signed-off-by:

ds_write_bit doesn't read the input buffer, so add COMM_ICP and a comment that it will no longer generate a read back data byte. If there is an extra data byte later on then it will cause an error and discard what data was there. Corrected operator ordering for ds_send_control. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

w1_reset_bus, added some comments about the timing and switched to msleep for the later delay. I don't have the hardware to test the sleep after reset change. The one wire doesn't have a timing requirement between commands so it is fine. I do have the USB hardware and it would be in big trouble with 10ms interrupt transfers to find that the reset completed. Signed-off-by:

Fixed data reading bug by replacing binary attribute with device one. Switching the sysfs read from bin_attribute to device_attribute. The data is far under PAGE_SIZE so the binary interface isn't required. As the device_attribute interface will make one call to w1_therm_read per file open and buffer, the result is, the following problems go away. buffer overflow: Execute a short read on w1_slave and w1_therm_read_bin would still return the full string size worth of data clobbering the user space buffer when it returned. Switching to device_attribute avoids the buffer overflow problems. With the snprintf formatted output dealing with short reads without doing a conversion per read would have been difficult. bad behavior: `cat w1_slave` would cause two temperature conversions to take place. Previously the code assumed W1_SLAVE_DATA_SIZE would be returned with each read. It would not return 0 unless the offset was less than W1_SLAVE_DATA_SIZE. The result was the first read did a temperature conversion, filled the buffer and returned, the offset in the second read would be less than W1_SLAVE_DATA_SIZE and also fill the buffer and return, the third read would finnally have a big enough offset to return 0 and cause cat to stop. Now w1_therm_read will be called at most once per open. Signed-off-by:
