2012-07-13Input: spear_keyboard - fix clock handling during suspend/resumeShiraz Hashim1-8/+10
SPEAr keyboard should normally disable clock during suspend and enable it during resume. For cases where it is expected to act as a wakeup source the clock can remain in the same state i.e. kept enabled if it is being used.

2012-07-07Input: ff-memless - fix a couple min_t() castsDan Carpenter1-2/+2
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.

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.

2012-06-30acpi_pad: fix power_saving thread deadlockStuart Hayes1-3/+4
The acpi_pad driver can get stuck in destroy_power_saving_task() waiting for kthread_stop() to stop a power_saving thread. The problem is that the isolated_cpus_lock mutex is owned when destroy_power_saving_task() calls kthread_stop(), which waits for a power_saving thread to end, and the power_saving thread tries to acquire the isolated_cpus_lock when it calls round_robin_cpu(). This patch fixes the issue by making round_robin_cpu() use its own mutex. https://bugzilla.kernel.org/show_bug.cgi?id=42981 Cc: [email protected] Signed-off-by: Stuart Hayes <[email protected]> Signed-off-by: Len Brown <[email protected]>

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 - 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 <[email protected]> Signed-off-by: Henrik Rydberg <[email protected]>
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 <[email protected]> Signed-off-by: Henrik Rydberg <[email protected]>

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 <[email protected]> Signed-off-by: Henrik Rydberg <[email protected]>

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.
