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. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.

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.

2009-04-15Input: 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.

2009-01-12Input: corgi_ts - mark probe function as __devinitUwe Kleine-König
A pointer to corgits_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.
