|/ | | | | | | | | | | | | | | | | | | According to the touch controller spec, SPI return a 16 bit value, only 12 bits are valid, they are bit[14-3]. The value of MISO and MOSI can be configured when SPI is in idle mode. Currently this touch driver assumes the SPI bus sets the MOSI and MISO in low level when SPI bus is in idle mode. So the bit[15] of the value got from SPI bus is always 0. But when SPI bus congfigures the MOSI and MISO in high level during the SPI idle mode, the bit[15] of the value get from SPI is always 1. If bit[15] is not masked, we may get the wrong value. Mask the invalid bit to make sure the correct value gets returned. Regardless of the SPI bus idle configuration.

* Input: ads7846 - switch to using threaded IRQJason Wang2010-10-181-430/+456
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit 9114337 introduces regulator operations in ads7846 touchscreen driver. Among these operations, some are called while holding a spinlock. On many platforms regulators reside on slow buses, such as I2C/SPI and require sleep while accessing them. The touchscreen itself is also a SPI device and currently relies on asynchronous SPI access to avoid sleeping in interrupt context. Let's switch to using threaded IRQ to be able to access SPI bus synchronously (which simplifies driver a bit); it also allows safe access to the regulators as well. This has been tested on the ti_omap3530evm board: 1) using ts_lib after normal boot 2) using ts_lib after "#echo 1/0 > /sys/bus/spi/devices/spi0.1/disable" 3) using ts_lib after "#echo mem > /sys/power/state" and "wake up" Also tested on pandora.

* Input: ads7846 - extend the driver for ads7845 controller supportAnatolij Gustschin2010-07-031-37/+135
| | | | | | | | | | | | | | | | | | ADS7845 is a controller for 5-wire touch screens and somewhat different from 7846. It requires three serial communications to accomplish one complete conversion. Unlike 7846 it doesn't allow Z1-/Z2- position measurement. The patch extends the ads7846 driver to also support ads7845. The packet struct is extended to contain needed command and conversion buffers. ads7846_rx() and ads7846_rx_val() now differentiate between 7845 and 7846 case. ads7846_probe() is modified to setup ads7845 specific command and conversion messages and to switch ads7845 into power-down mode, since this is needed to be prepared to respond to pendown interrupts.

* Input: ads7846 - return error on regulator_get() failureKevin Hilman2010-05-271-2/+2
| | | | | | | | | | | | | | | | | | | | In probe(), if regulator_get() failed, an error code was not being returned causing the driver to be successfully bound, even though probe failed. This in turn caused the suspend, resume and remove methods to be registered and accessed via the SPI core. Since these functions all access private driver data using pointers that had been freed during the failed probe, this would lead to unpredictable behavior. This patch ensures that probe() returns an error code in this failure case so the driver is not bound. Found using lockdep and noticing the lock used in the suspend/resum path pointed to a bogus lock due to the freed memory.

* spi: prefix modalias with "spi:"Anton Vorontsov2009-09-231-0/+1
| | | | | | | | | | | | | | | | | | | | | This makes it consistent with other buses (platform, i2c, vio, ...). I'm not sure why we use the prefixes, but there must be a reason. This was easy enough to do it, and I did it.

* Input: ads7846 - pin change interrupt supportMichael Roth2009-06-111-3/+9
| | | | | | | | | | | | | | 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.
