Input: add imx-keypad driver to support the IMX Keypad Port

2010-02-01T01:52:57+00:00

The IMX family of Application Processors is shipped with a Keypad Port supported by this driver. The peripheral can control up to an 8x8 matrix key pad where all the scanning is done via software. The hardware provides two interrupts: one for key presses (KDI) and one for all key releases (KRI). There is also a simple circuit for glitch reduction (said for synchronization) made by two series of 3 D-latches clocked by the keypad-clock that stabilize the interrupts sources. KDI and KRI are fired only if the respective conditions are maintained for at last 4 keypad-clock cycle. Since those circuits are poor for a correct debounce process (the keypad-clock frequency is 32K and bounces longer than 94us are not masked) the driver, when an interrupt arrives, samples the matrix with a period of 10ms until the readins are stable for IMX_KEYPAD_SCANS_FOR_STABILITY times (currently set at 3). After getting stable result appropriate events are sent through the input stack. If some keys are maintained pressed, the driver continues to scan the matrix with a longer period (60ms) to catch possible multiple key presses without overloading the cpu. This process ends when all keys are released. This driver is tested to build in kernel or as a module and follow the specification of Freescale Application processors: i.MX25 i.MX27 i.MX31 i.MX35 i.MX51 especially tested on i.MX31.

Input: add support for generic GPIO-based matrix keypad

2009-06-29T07:30:16+00:00

Original patch by Marek Vasut, modified by Eric in: 1. use delayed work to simplify the debouncing 2. combine col_polarity/row_polarity into a single active_low field 3. use a generic bit array based XOR algorithm to detect key press/release, which should make the column assertion time shorter and code a bit cleaner 4. remove the ALT_FN handling, which is no way generic, the ALT_FN key should be treated as no different from other keys, and translation will be done by user space by commands like 'loadkeys'. 5. explicitly disable row IRQs and flush potential pending work, and schedule an immediate scan after resuming as suggested by Uli Luckas 6. incorporate review comments from many others Patch tested on Littleton/PXA310 (though PXA310 has a dedicate keypad controller, I have to configure those pins as generic GPIO to use this driver, works quite well, though), and Sharp Zaurus model SL-C7x0 and SL-C1000.
