2009-08-21Input: ucb1400_ts - enable interrupt unconditionallyPavel Revak
Sometimes, when using the touchscreen, it stops working till next restart and the following message is printed: ucb1400: unexpected IE_STATUS = 0x0 The following patch retriggers the touchscreen interrupt unconditionally. This prevents hanging of the touchscreen in case of bogus interrupt occurence.

2009-08-21Input: ucb1400_ts - enable ADC FilterMarek Vasut
This patch enables ADC filtering on UCB1400 codec by default. The benefit from this change is mostly on some Colibri boards where the ADCSYNC pin of the UCB1400 codec isn't connected causing the touchscreen to jitter very badly. This change has no visible effect on boards where the ADCSYNC pin is connected.

2009-08-12Input: eeti_ts - allow active high irq linesDaniel Mack
This adds a struct eeti_ts_platform_data which currently holds only one value to specify the interrupt polarity. The driver has a fallback if no platform data is passed in via the i2c_board_info, so no regression is caused.

2009-07-20Input: wm97xx - add possibility to control the GPIO_STATUS shiftMarek Vasut
This patch allows tweaking the behaviour of GPIO_STATUS register shift quirk that's in wm97xx-core. The problem with GPIO_STATUS register being shifted by one doesn't appear on all hardware it seems and causes problems with accelerated touchscreen drivers on Palm hardware. Therefore an accelerated touchscreen driver can select if the shift is/isn't happening on the hardware.

2009-07-12Input: ucb1400_ts - fix a misleading function nameHans J. Koch
The driver for UCB1400 touchscreen controllers contains a function named ucb1400_ts_pen_down(), but it returns 0 if the pen is down and 1 if it's up. This causes confusion, especially since it's used as a boolean truth value later in the code. This patch renames it. Signed-off-by: Hans J.

2009-06-11Input: ads7846 - pin change interrupt supportMichael Roth
Some SoCs support only pin change interrupts on GPIO pins used as irq lines. The ads7846 core is not affected from the additional irqs on the rising edge because the code accounts touch bounce anyway by kicking in a timer and disabling the irq after the first request and reenabling the irq after a timeout when there is no longer pen down detected.

2009-06-11Input: add support for touchscreen on W90P910 ARM platformWan ZongShun
The touchscreen works in two modes, wait trigger mode and auto-semi mode. The device starts in wait trigger mode and waits until pressure is detected, then device sets WT_INT bit and raises an interrupt. The driver should put the device into auto-semi mode and prepare for reading first X and then Y coordinates. When coordinate data is ready the driver sets ADC_INT bit and raises interrupt again.

2009-05-01Input: wm97xx - do not access dev->driver_data directlyGreg Kroah-Hartman
In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used.

2009-04-18Input: add wm97xx accelerated driver for Atmel microprocessorsHans-Christian Egtvedt
This patch adds an accelerated driver for Atmel AVR32 AT32AP700X microprocessors. It uses interrupts on the channel B in the AC97 controller. Thus, offloading the work queue in the wm97xx-ts driver. The driver has been tested with Atmel AVR32 AT32AP7000 and Wolfson WM9712 codec. The driver can also be easily modified to support Atmel AT91 devices, as AT91 and AVR32 share the same AC97C module.

2009-04-17Input: ucb1400 - use disable_irq_nosync() in irq handlerBen Nizette

2009-04-15Input: ads7846 - fix unsafe disable_irqBen Nizette
The use of disable_irq inside the handler for the interrupt being disabled has always been dangerous. disable_irq should wait for that handler to complete before returning -> deadlock. For some reason this wasn't actually the case until 3aa551c9b was merged but since this time, the ads7846 driver has deadlocked the system on first interrupt.
