| | * Input: spear_keyboard - reconfigure operating frequency on suspendShiraz Hashim2012-07-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some platform it may happen that the input clock to keyboard may change during suspend, thus impacting its wakeup capability. There is no means for keyboard driver to know this frequency before hand. Hence introduce a platform data 'suspended_rate' which indicates the frequency during suspend at which keyboard operates. Accordingly reprogram keyboard while going into suspend and restore original configuration at the time of resume.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SPEAr keyboard should normally disable clock during suspend and enable it during resume.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | envelope->attack_level is a u16 type. We're trying to clamp it here so it's between 0 and 0x7fff. Unfortunately, the cast to __s16 turns all the values larger than 0x7fff into negative numbers and min_t() thinks they are less than 0x7fff. envelope_level is an int so now we've got negative values stored there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dmitry: I understand that I am a bit late to the party :) but I do not agree with this change. Failure to create attributes is not sometihng that user could cause (at least not easily) and thus would not be a setup issue but something more severe. I believe we should fail loading the driver so sysfs attribute breakage will be noticed as soon as possible, instead of discovering it much much later in the process.

| | | * Input: atmel_mxt_ts - use T9 reportid range to init number of mt slotsDaniel Kurtz2012-06-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Atmel mxt devices can report one finger for each T9 reportid. Therefore, this range can be used to report the max number of MT-B slots to userspace instead of assuming a fixed 10. Note that mxt_initialized() must complete early, since the input_dev properties now depend on values in the object table.

| | | * Input: atmel_mxt_ts - cache T9 reportid range when reading object tableDaniel Kurtz2012-06-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Streamline interrupt processing by caching the T9 reportid range when first reading the object table. In the process, refactor reading the object descriptor table. First, since the object_table entries are now exactly the same layout in device memory and in the driver, allocate an appropriately sized array and fetch the entire table directly into it in a single i2c transaction. Since a 6 byte table object requires 10 bytes to read, doing this dramatically reduces overhead. Note: The cached T9 reportid's are initialized to 0, which is an invalid reportid. Thus, the checks in the interrupt handler will always fail for devices that do not support the T9 object. Therefore, after doing a firmware update, the old object table is destroyed and all cached object values are reset to 0, before reading the new object table, in case the new firmware does not have the old objects. This patch tested on an MXT224E. Signed-off-by: Daniel Kurtz <djkurtz@chromium.org> Signed-off-by: Henrik Rydberg <rydberg@euromail.se>
| | | * Input: atmel_mxt_ts - refactor when and how object table is freedDaniel Kurtz2012-06-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Object Table is freed in three cases: 1) When the driver is being removed. 2) In the error path of mxt_initialize(). 3) Just after a firmware update, when a new object table is about to be read. For cases 2 & 3, the driver is not immediately unloaded, so this patch refactors these cases to use a common cleanup function. It also refactors the mxt_initialize error paths to ensure that this cleanup happens. Note: mxt_update_fw_store() does not handle errors during mxt_initialize(). A proposed fix for this is in a subsequent patchset. Signed-off-by: Daniel Kurtz <djkurtz@chromium.org> Signed-off-by: Henrik Rydberg <rydberg@euromail.se>

Note: this driver does not really do MT-B properly. Each input report (a group of input events followed by a SYN_REPORT) only contains data for a single contact. When multiple fingers are present on a device, each is properly reported in its own MT_SLOT. However, there is only ever one MT_SLOT per SYN_REPORT. This is fixed in a subsequent patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i2c bus requires 4 bytes to do a 1-byte write (1 byte i2c address + 2 byte offset + 1 byte data). By taking a length with writes, the driver can amortize transaction overhead by performing larger transactions where appropriate. This patch just sets up the new API. Later patches refactor writes to take advantage of the larger transactions. Signed-off-by: Daniel Kurtz <djkurtz@chromium.org> Signed-off-by: Henrik Rydberg <rydberg@euromail.se>

Transposed axis can be typically corrected by touch screen calibration however this bug also negatively influences touch pressure measurements. Add an option to correct x and y axis.
