[PATCH] Input: ucb1400 - set up driver's name to show in sysfs

2007-04-11T00:26:33+00:00

The UCB1400 is missing a name parameter in the device_driver struct.
This causes missing information in the /sys tree and seems to cause
other problems with the AC97 functionality. This was tested on a PXA270
system.

[PATCH] hrtimers: namespace and enum cleanup

2007-02-16T16:13:58+00:00

- hrtimers did not use the hrtimer_restart enum and relied on the implict
  int representation. Fix the prototypes and the functions using the enums.
- Use seperate name spaces for the enumerations
- Convert hrtimer_restart macro to inline function
- Add comments

No functional changes.

Input: ads7846 - be more compatible with the hwmon framework

2007-01-18T05:45:48+00:00

 - Hook up to hwmon
     * show sensor attributes only if hwmon is present
     * ... and the board's reference voltage is known
     * otherwise be just a touchscreen
 - Report voltages per hwmon convention
     * measure in millivolts
     * voltages are named in[0-8]_input (ugh)
     * for 7846 chips, properly range-adjust vBATT/in1_input

Battery measurements help during recharge monitoring.  On OSK/Mistral,
the measured voltage agreed with a multimeter to several decimal places.

Input: ads7846 - detect pen up from GPIO state

2007-01-18T05:45:43+00:00

We can't depend on the pressure value to determine when the pen was
lifted, so use the GPIO line state instead. This also helps with
chips (like ads7843) that don't have pressure sensors.

Input: ads7846 - select correct SPI mode

2007-01-18T05:45:38+00:00

Talk to ADS7846 chip using SPI mode 1, which is what the chip
supports: writes on falling clock edge, reads on rising.

Input: ads7846 - switch to using hrtimer

2007-01-18T05:45:31+00:00

Use hrtimer instead of the normal timer, since it provides better
sampling resolution. This will:

 - avoid a problem where we have a 1 jiffy poll period and
   dynamic tick on
 - utilize high resolution HW clocks when they are added to
   the hrtimer framework

Input: ads7846 - optionally leave Vref on during differential measurements

2007-01-18T05:45:21+00:00

On some LCDs leaving the Vref on provides much better readings.

Input: ads7846 - pluggable filtering logic

2007-01-18T05:44:41+00:00

Some LCDs like the LS041Y3 require a customized filtering
logic for reliable readings, so make the filtering function
replacable through platform specific hooks.
