2010-07-13Input: atlas_btns - adds a missing owner field for atlas_acpi_driverAxel Lin1-0/+1
The owner field provides the link between drivers and modules in sysfs. After setting the owner field, we can see which module provides which driver and vice versa by looking at /sys/bus/acpi/drivers/Atlas ACPI/module and /sys/module/atlas_btns/drivers/acpi:Atlas ACPI Signed-off-by: Axel Lin <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>

2010-07-09powerpc: Add i8042 keyboard and mouse irq parsingMartyn Welch1-0/+5
Currently the irqs for the i8042, which historically provides keyboard and mouse (aux) support, is hardwired in the driver rather than parsing the dts. This patch modifies the powerpc legacy IO code to attempt to parse the device tree for this information, failing back to the hardcoded values if it fails.

2010-07-03Input: ads7846 - extend the driver for ads7845 controller supportAnatolij Gustschin1-37/+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.

2010-06-28sparc/of: Move of_device fields into struct pdev_archdataGrant Likely1-4/+4
This patch moves SPARC architecture specific data members out of struct of_device and into the pdev_archdata structure. The reason for this change is to unify the struct of_device definition amongst all the architectures. It also remvoes the .sysdata, .slot, .portid and .clock_freq properties because they aren't actually used by anything. A subsequent patch will replace struct of_device entirely with struct platform_device and the of_platform support code will share common routines with the platform bus (but the bus instances themselves can remain separate). This patch also adds 'struct resources *resource' and num_resources to match the fields defined in struct platform_device. After this change, 'struct platform_device' can be used as a drop-in replacement for 'struct of_platform'. This change is in preparation for merging the of_platform_bus_type with the platform_bus_type. Signed-off-by: Grant Likely <[email protected]> Acked-by: David S.

gpiolib now has debounce support added in .35, so let's make use of it. This allows to use hardware GPIO debouncing on some platforms like OMAP.

2010-06-24Input: adp5588-keys - support GPI events for ADP5588 devicesXiaolong CHEN1-7/+127
A column or row configured as a GPI can be programmed to be part of the key event table and therefore also capable of generating a key event interrupt. A key event interrupt caused by a GPI follows the same process flow as a key event interrupt caused by a key press. GPIs configured as part of the key event table allow single key switches and other GPI interrupts to be monitored. As part of the event table, GPIs are represented by the decimal value 97 (0x61 or 1100001) through the decimal value 114 (0x72 or 1110010). See table below for GPI event number assignments for rows and columns.

2010-06-23Input: evdev - never leave the client buffer empty after writeHenrik Rydberg1-3/+7
When the client buffer is very small and wraps around a lot, it may well be that a write increases the head such that head == tail. If this happens between the point where a poll is triggered and the actual data is being read, there will be no data to read. This is confusing to applications, which might end up closing the file. This patch solves the problem by making sure the client buffer is never empty after writing to it. Signed-off-by: Henrik Rydberg <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>
2010-06-23Input: bcm5974 - set the average number of events per MT event packetHenrik Rydberg1-0/+2

2010-06-23Input: evdev - use driver hint to compute size of event bufferHenrik Rydberg1-2/+7
Some devices, in particular MT devices, produce a lot of data. This may lead to overflowing of the event queues in evdev driver, which by default are fairly small. Let the drivers hint the average number of events per packet generated by the device, and use that information when computing the buffer size evdev should use for the device.

2010-06-08Input: ad7877 - fix spi word size to 16 bitOskar Schirmer1-0/+7
With no word size given in the users platform data, a generic spi host controller driver will assume a default word size of eight bit. This causes transmission to be performed bytewise, which will fail on little endian machines for sure. Failure on big endian depends on usage of slave select to mark word boundaries. Anyway, ad7877 is specified to work with 16 bit per word, so unconditionally set the word size accordingly. Flag an error where 16 bit per word is not available.

2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang12-20/+1
I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.
