Input: usbtouchscreen - separate report and transmit buffer size handling

2013-12-20T15:45:08Z

commit 4ef38351d770cc421f4a0c7a849fd13207fc5741 upstream. This patch supports the separate handling of the USB transfer buffer length and the length of the buffer used for multi packet support. For devices supporting multiple report or diagnostic packets, the USB transfer size is now limited to the USB endpoints wMaxPacketSize - otherwise it defaults to the configured report packet size as before. This fixes an issue where event reporting can be delayed for an arbitrary time for multi packet devices. For instance the report size for eGalax devices is defined to the 16 byte maximum diagnostic packet size as opposed to the 5 byte report packet size. In case the driver requests 16 byte from the USB interrupt endpoint, the USB host controller driver needs to split up the request into 2 accesses according to the endpoints wMaxPacketSize of 8 byte. When the first transfer is answered by the eGalax device with not less than the full 8 byte requested, the host controller has got no way of knowing whether the touch controller has got additional data queued and will issue the second transfer. If per example a liftoff event finishes at such a wMaxPacketSize boundary, the data will not be available to the usbtouch driver until a further event is triggered and transfered to the host. From user perspective the BTN_TOUCH release event in this case is stuck until the next touch down event.

commit ae2aa3a512fa5f50f67feba9e66bc2efb394bd63 upstream. The HID driver now handles these devices, regardless of what protocol the device claims it supports. Signed-off-by: Forest Bond Acked-by: Dmitry Torokhov Signed-off-by: Jiri Kosina Signed-off-by: Greg Kroah-Hartman

Input: cyttsp - fix swapped mfg_stat and mfg_cmd registers

2013-06-06T05:46:37Z

The command and status register in the driver were swapped with respect to the order specified in the datasheet (CY8CTMA140). Confirmed with Cypress that the order in the datasheet is correct. Signed-off-by: Matthias Kaehlcke Acked-by: Javier Martinez Canillas Signed-off-by: Dmitry Torokhov

Input: cyttsp - add missing handshake

2013-06-06T05:46:34Z

For the devices that has blocking with timeout communication, these extra handshakes will prevent one timeout delay in startup sequence Tested-by: Ferruh Yigit on TMA300-DVK Signed-off-by: Ferruh Yigit Acked-by: Javier Martinez Canillas Signed-off-by: Dmitry Torokhov

Input: cyttsp - fix memcpy size param

2013-06-06T05:46:30Z

memcpy param is wrong because of offset in bl_cmd, this may corrupt the stack which may cause a crash. Tested-by: Ferruh Yigit on TMA300-DVK Signed-off-by: Ferruh Yigit Acked-by: Javier Martinez Canillas Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov

Input: egalax_ts - ABS_MT_POSITION_Y not reported well

2013-05-06T03:13:10Z

The egalax_ts touchscreen modul not report ABS_MT_POSITION_Y proper. As result it may be, that upper software levels only receive x coordinates well. Signed-off-by: Heiko Abraham Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov

Input: st1232 - add reset pin handling

2013-04-15T17:00:44Z

We add the possibility to hand over a GPIO number for the reset pin. This way we can remove existing board code that takes care of it and group this information properly in the platform data or in the device tree configuration.

Use the devm_* managed functions to allocate resources. Signed-off-by: Laurent Pinchart Signed-off-by: Dmitry Torokhov

Input: ad7877 - use spi_get_drvdata() and spi_set_drvdata()

2013-04-08T04:02:25Z

Use the wrapper functions for getting and setting the driver data using spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we can directly pass a struct spi_device. Signed-off-by: Jingoo Han Signed-off-by: Dmitry Torokhov
