2006-04-26Input: ads7846 - improve filtering for thumb press accuracyImre Deak
Providing more accurate coordinates for thumb press requires additional steps in the filtering logic: - Ignore samples found invalid by the debouncing logic, or the ones that have out of bound pressure value. - Add a parameter to repeat debouncing, so that more then two consecutive good readings are required for a valid sample.

2006-04-26Input: ads7846 - report 0 pressure value along with pen up eventImre Deak

2006-04-11Input: ads7846 - handle IRQs that were latched during disabled IRQsImre Deak
The pen down IRQ will toggle during each X,Y,Z measurement cycle. Even though the IRQ is disabled it will be latched and delivered when after enable_irq. Thus in the IRQ handler we must avoid starting a new measurement cycle when such an "unwanted" IRQ happens. Add a get_pendown_state platform function, which will probably determine this by reading the current GPIO level of the pen IRQ pin. Move the IRQ reenabling from the SPI RX function to the timer. After the last power down message the pen IRQ pin is still active for a while and get_pendown_state would report incorrectly a pen down state. When suspending we should check the ts->pending flag instead of ts->pendown, since the timer can be pending regardless of ts->pendown. Also if ts->pending is set we can be sure that the timer is running, so no need to rearm it. Similarly if ts->pending is not set we can be sure that the IRQ is enabled (and the timer is not).

2006-01-13[PATCH] spi: ads7846 driverDavid Brownell
This is a driver for the ADS7846 touchscreen sensor, derived from the corgi_ts and omap_ts drivers. Key differences from those two: - Uses the new SPI framework (minimalist version) - <linux/spi/ads7846.h> abstracts board-specific touchscreen info - Sysfs attributes for the temperature and voltage sensors - Uses fewer ARM-specific IRQ primitives The temperature and voltage sensors show up in sysfs like this: $ pwd /sys/devices/platform/omap-uwire/spi2.0 $ ls bus@ input:event0@ power/ temp1 vbatt driver@ modalias temp0 vaux $ cat modalias ads7846 $ cat temp0 991 $ cat temp1 1177 $ So far only basic testing has been done. There's a fair amount of hardware that uses this sensor, and which also runs Linux, which should eventually be able to use this driver. One portability note may be of special interest. It turns out that not all SPI controllers are happy issuing requests that do things like "write 8 bit command, read 12 bit response". Most of them seem happy to handle various word sizes, so the issue isn't "12 bit response" but rather "different rx and tx write sizes", despite that being a common MicroWire convention. So this version of the driver no longer reads 12 bit native-endian words; it reads 16-bit big-endian responses, then byteswaps them and shifts the results to discard the noise.

2005-10-28[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King
In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
