hwmon: (ams) Convert to a new-style i2c driver
The legacy i2c binding model is phasing out, so the ams driver needs
to be converted to a new-style i2c driver. Here is a naive approach of
this conversion. Basically it is moving the i2c device creation from
the ams driver to the i2c-powermac driver. This should work, but I
suspect we could come up with something cleaner by declaring the i2c
device as part of the platform setup. This could be done later by
someone more familiar with openfirmware-based platforms than I am
myself.
One nice thing brought by this conversion is that the ams driver
should be loaded automatically on systems where is is needed (at
least when the I2C interface to the chip is used) providing
coldplug-aware user-space environment.

W1: ds2490.c optimize ds_set_pullup
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.

W1: ds2490.c simplify and fix ds_touch_bit
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.

W1: w1_therm fix user buffer overflow and cat
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.

W1: feature, enable hardware strong pullup
Add a strong pullup option to the w1 system. This supplies extra power
for parasite powered devices. There is a w1_master_pullup sysfs entry and
enable_pullup module parameter to enable or disable the strong pullup.
The one wire bus requires at a minimum one wire and ground. The common
wire is used for sending and receiving data as well as supplying power to
devices that are parasite powered of which temperature sensors can be one
example. The bus must be idle and left high while a temperature
conversion is in progress, in addition the normal pullup resister on
larger networks or even higher temperatures might not supply enough power.
The pullup resister can't provide too much pullup current, because
devices need to pull the bus down to write a value. This enables the
strong pullup for supported hardware, which can supply more current when
requested. Unsupported hardware will just delay with the bus high.
The hardware USB 2490 one wire bus master has a bit on some commands which
will enable the strong pullup as soon as the command finishes executing.
To use strong pullup, call the new w1_next_pullup function to register the
duration. The next write command will call set_pullup before sending the
data, and reset the duration to zero once it returns.
