gpiolib: fix poll(2) support reconfigure on sysfs polarity change

2010-01-11T17:34:06+00:00

Previously enabled poll(2) support on one edge was never reconfigured when
sysfs polarity change was triggered from kernel, because 'struct device
*dev' shadowed an earlier definition.

Found by sparse, which I should've run much earlier.

gpiolib: add support for changing value polarity in sysfs

2009-12-16T15:20:01+00:00

Drivers may use gpiolib sysfs as part of their public user space
interface. The GPIO number and polarity might change from board to
board. The gpio_export_link() call can be used to hide the GPIO number
from user space. Add support for also hiding the GPIO line polarity
changes from user space.

gpio: add GPIO driver for the Timberdale FPGA

2009-12-16T15:20:00+00:00

A GPIO driver for the Timberdale FPGA found on the Intel Atom board
Russellville.

The GPIO driver also has an IRQ-chip to support interrupts on the pins.

gpio: fix test on unsigned in lnw_irq_type()

2009-12-16T15:20:00+00:00

The wrong test was used, gpio is unsigned and it had an off-by-one.

cs5535: drop the Geode-specific MFGPT/GPIO code

2009-12-15T16:53:28+00:00

With generic modular drivers handling all of this stuff, the
geode-specific code can go away.  The cs5535-gpio, cs5535-mfgpt, and
cs5535-clockevt drivers now handle this.

cs5535-gpio: request function, mask & names added

2009-12-15T16:53:27+00:00

Changed number of gpio pins to 32 (according to datasheet)

Added mask to disable some pins

Added gpio_request for checking mask and disabling special pin functions

Added pin names

cs5535-gpio: add AMD CS5535/CS5536 GPIO driver support

2009-12-15T16:53:27+00:00

This creates a CS5535/CS5536 GPIO driver which uses a gpio_chip backend
(allowing GPIO users to use the generic GPIO API if desired) while also
allowing architecture-specific users directly (via the cs5535_gpio_*
functions).

Tested on an OLPC machine.  Some Leemotes also use CS5536 (with a mips
cpu), which is why this is in drivers/gpio rather than arch/x86.
Currently, it conflicts with older geode GPIO support; once MFGPT support
is reworked to also be more generic, the older geode code will be removed.

This patch renames function names like twl4030_i2c_write_u8,
twl4030_i2c_read_u8 to twl_i2c_write_u8, twl_i2c_read_u8
and also common variable in twl-core.c

mfd: Rename twl4030* driver files to enable re-use

2009-12-13T19:05:51+00:00

The upcoming TWL6030 is companion chip for OMAP4 like the current TWL4030
for OMAP3. The common modules like RTC, Regulator creates opportunity
to re-use the most of the code from twl4030.

This patch renames few common drivers twl4030* files to twl* to enable
the code re-use.
