2012-07-05Revert "Input: atmel_mxt_ts - warn if sysfs could not be created"Henrik Rydberg1-1/+4
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.

2012-07-05Input: request threaded-only IRQs with IRQF_ONESHOTLars-Peter Clausen17-23/+34
Since commit 1c6c69525b ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail. This patch adds the IRQF_ONESHOT to input drivers where it is missing. Not modified by this patch are those drivers where the requested IRQ will always be a nested IRQ (e.g. because it's part of an MFD), since for this special case IRQF_ONESHOT is not required to be specified when requesting the IRQ.

2012-06-29Input: atmel_mxt_ts - parse T6 reportsDaniel Kurtz1-4/+19

2012-06-29Input: atmel_mxt_ts - send all MT-B slots in one input reportDaniel Kurtz1-5/+10
Each interrupt contains information for all contacts with changing properties. Process all of this information at once, and send it all in a a single input report (ie input events ending in EV_SYN/SYN_REPORT). This patch was tested using an MXT224E.

2012-06-29Input: atmel_mxt_ts - use T9 reportid range to init number of mt slotsDaniel Kurtz1-8/+8
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.

2012-06-29Input: atmel_mxt_ts - refactor reportid checking in mxt_interruptDaniel Kurtz1-6/+8
This small refactor is in preparation for checking more report types in the mxt_interrupt message processing loop. Signed-off-by: Daniel Kurtz <djkurtz@chromium.org> Signed-off-by: Henrik Rydberg <rydberg@euromail.se>
2012-06-29Input: atmel_mxt_ts - cache T9 reportid range when reading object tableDaniel Kurtz1-35/+41
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>
2012-06-29Input: atmel_mxt_ts - refactor when and how object table is freedDaniel Kurtz1-7/+16
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>

2012-06-29Input: atmel_mxt_ts - simplify event reportingDaniel Kurtz1-76/+13
Instead of carrying around per-finger state in the driver instance, just report each finger as it arrives to the input layer, and let the input layer (evdev) hold the event state (which it does anyway). 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. This patch was tested with an mXT224E. Signed-off-by: Daniel Kurtz <djkurtz@chromium.org> Signed-off-by: Henrik Rydberg <rydberg@euromail.se>

2012-06-29Input: atmel_mxt_ts - add variable length __mxt_write_regDaniel Kurtz1-5/+18
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.

The keypad could cause multiple interrupts to be fired in succession since we weren't waiting for the IRQs to clear properly in the interrupt handler. We wait for a number of bus iterations (the readl():s from the peripheral bus will stall, so these are quite long) before giving up on getting keys ready to read, then we sleep until the IRQ is deasserted (this is OK since the interrupt is threaded).

The twl6040 DT support implementation has been changed from the originally planned. None of the child devices going to have compatible_of property which means that the child devices of twl6040 will be created as traditional MFD devices. The mfd core driver will decide (based on the DT blob) to create a device for the twl6040-vibra or not. If the DT blob has 'vibra' section the device will be created without pdata. In this case the vibra driver will reach up to the parent node to get the needed properties. With DT booted kernel we no longer be able to link the regulators to the vibra driver, they can be only linked to the MFD device (probed via DT).
