| | | * | | | | Revert "Input: atmel_mxt_ts - warn if sysfs could not be created"Henrik Rydberg2012-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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>

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.

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). Also use the debounce platform data for another hardcoded wait loop.

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). From the vibra driver we ned to use pdev->dev.parent to get the regulators. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
