mfd: remove DS1WM clock handling

2009-04-04T22:32:22+00:00

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.

mfd: convert DS1WM to use MFD core

2009-04-04T22:32:20+00:00

This patch converts the DS1WM driver into an MFD cell. It also
calculates the bus_shift parameter from the memory resource size.

[ARM] MXC: remove _clk suffix from clock names

2009-03-13T09:33:48+00:00

The context makes it clear already that these are clocks, so there's
no need for such a suffix. This patch only changes the clocks actually
used in the tree. The remaining clocks are renamed in the subsequent
architecture specific patches.

drivers/w1/masters/w1-gpio.c: fix read_bit()

2009-03-12T23:20:23+00:00

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.

w1_ds2433: clear the validcrc flag after a write

2009-02-28T00:26:20+00:00

The w1_ds2433 driver does not read from the hardware if the CRC was valid
on the last read.  The validcrc flag should be cleared after a write so
that the new value can be read.

w1: w1 temp calculation overflow fix

2009-02-11T22:25:37+00:00

Addresses http://bugzilla.kernel.org/show_bug.cgi?id=12646

When the temperature exceeds 32767 milli-degrees the temperature overflows
to -32768 millidegrees.  These are bothe well within the -55 - +125 degree
range for the sensor.

Fix overflow in left-shift of a u8.
