2010-10-18Input: ad7877 - implement specified chip select behaviorMichael Hennerich1-1/+11
According to the AD7877 datasheet: Each transfer operation is 16-bit. If multiple read/write operations are to be performed, CS must be taken high after the end of each read/write operation before another read/write operation can be performed by taking CS low again. Make sure CS toggles after each transfer in the message. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2010-10-18Input: ads7846 - switch to using threaded IRQJason Wang1-430/+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.

2010-09-16Input: hid-input - allow mapping unknown usagesDmitry Torokhov1-4/+9
Currently HID layer only allows to remap keycodes for known usages, and responds with -EINVAL when user tries to map new usage code. This precludes us form relying on udev/keymap for establishing correct mappings and forces us to write dummy HID drivers responsible only for setting up keymaps. Let's allow remapping not only usages that have been set up as keys (usage->type == EV_KEY) but also yet-unmapped usages (usage->type == 0).

2010-09-10Input: add support for large scancodesMauro Carvalho Chehab3-75/+248
Several devices use a high number of bits for scancodes. One important group is the Remote Controllers. Some new protocols like RC-6 define a scancode space of 64 bits. The current EVIO[CS]GKEYCODE ioctls allow replace the scancode/keycode translation tables, but it is limited to up to 32 bits for scancode. Also, if userspace wants to clean the existing table, replacing it by a new one, it needs to run a loop calling the ioctls over the entire sparse scancode space. To solve those problems, this patch extends the ioctls to allow drivers handle scancodes up to 32 bytes long (the length could be extended in the future should such need arise) and allow userspace to query and set scancode to keycode mappings not only by scancode but also by index. Compatibility code were also added to handle the old format of EVIO[CS]GKEYCODE ioctls. Folded fixes by: - Dan Carpenter: locking fixes for the original implementation - Jarod Wilson: fix crash when setting keycode and wiring up get/set handlers in original implementation. - Dmitry Torokhov: rework to consolidate old and new scancode handling, provide options to act either by index or scancode.

2010-09-05Input: wacom - add a quirk for low resolution Bamboo devicesHenrik Rydberg2-0/+11
The Bamboo Touch reports a sub-screen resolution of 480x320. The signal-to-noise ratio is only about 100, so filtering is needed in order to reduce the jitter to a usable level. However, the low resolution leads to round-off errors in the EWMA filter, resulting in extremely jerky pointer motion. This patch explicitly sets a higher resolution for those devices, and tells this to the completion handler via a low-resolution quirk.
