This change allows torch and flash triggers to be turned on at varying brightness levels. As a bonus, it fixes a crash that occurs when enabling the front flash (in sdm630-nile-discovery_camera.dtsi) on discovery. Change-Id: Ic24b147f6e54ddc746b9cef3d73fdc51ce68500d Signed-off-by: MarijnS95 <[email protected]>
After updating the flash drivers (see previous commit), front flash now functions correctly without crashing on boot. Change-Id: Ibec34abeb06f413a29ce07bf4436d4e64662a467 Signed-off-by: MarijnS95 <[email protected]>

On kernel 4.9 the Android wakelocks are finally gone. Convert the driver to use the wakeup sources in the Linux PM API to achieve the very same goal. Signed-off-by: Pablo Mendez Hernandez <[email protected]>
A poll interface allows applications to wait for a specified timeout or indefinitely, while at the same time blocking on other file descriptors such as an eventfd. This is in contrast to the blocking ioctl which requires a wakeup every so often to check if another event (such as cancellation) is requested. This wakeup was configured at approximately .5 seconds, spamming the log and eating useless cpu cycles. Change-Id: Ieb34f0d731f257f6789c2d1977435d0d46a1dc4e Signed-off-by: MarijnS95 <[email protected]>
poll_wait simply adds the file handle to the waitqueue; the poll handler itself is supposed to return 0 when nothing happened, to go into a waiting state. As soon as the waitqueue triggers, the poll function is evaluated again and wakes up userspace when an event is returned.

The current polling state has a tendency to run into race conditions with device suspend, where the irq_fired flag may have not been cleared before a suspend is requested. This is particularly evident when a finger is still on the sensor; the HAL waits for it to disappear while the wakelock times out and fires off the suspend. Which in itself is another issue that is resolved in future commits. Furthermore, irq_wake is disabled unconditionally, causing "unbalanced disable" warnings every so often.

As soon as a blocking poll is entered no processing has to happen until the IRQ fires. Preemptively relaxing the wakelock saves unnecessary wakeup time when the driver/userspace is not doing anything. Change-Id: I286cb236c9f11eeda6698a15842f6804f9104a40 Signed-off-by: MarijnS95 <[email protected]>
Devices have a wakeup_source embedded in them which can be accessed without double-underscore prefixed pm_wakeup functions. Change-Id: I80bdf4e352bd6b022d022260f5fe274f7d682c97 Signed-off-by: MarijnS95 <[email protected]>
The fingerprint hal blocks/loops for as long a finger is touching the sensor before going back to polling. If an object stays on the sensor too long, the wakelock times out before the HAL has decided to wake up the system, causing it to freeze up before reaching the polling state. The wake-enabled IRQ is only able to wake the process in that polling state. With this change the HAL is able to signal that it needs a little longer before freezing up the CPU. This explicit approach has been chosen over an infinite (pm_keep_awake) wakelock, which needs a synchronisation point to release the wakelock. If this is not called, the system never goes back to sleep. Change-Id: Ib53fd96d70b030cd7c2d02da0bb8db180589daea Signed-off-by: MarijnS95 <[email protected]>

Using private_data fields instead of a global variable is necessary if multiple devices are ever supposed to be using the same driver. Even though this is not planned, reducing global state in favor of local state scoped to a specific device is preferred. Of course, this per-device datastructure should not be the drvdata for the entire platform_driver. Change-Id: I082fef63eefa8ec1631c98e6d7fcc47b29a235eb Signed-off-by: MarijnS95 <[email protected]>
The original et510-spi driver has seen a lot of alteration with unformatted and commented-out code all over the place. Fpc on the other hand has been steadily maintained, and has support for more granular power and irq_wake management, saving battery life.

Nile devices can be fitted with either sensor. This driver will disable itself when the other (FPC) sensor type is detected, allowing the FPC driver to take over. The RHWTYPE ioctl has been added for the HAL to figure out which of the drivers is actually in use. Change-Id: Ia7a2129e332815587dab9f960755175d8ce0e994 Signed-off-by: MarijnS95 <[email protected]>
The FPC driver needs to be disabled if Egistec hardware is detected on the Nile platform. This requires a slightly different driver to be loaded, as well as changes in the HAL. Change-Id: Iacb94ec7bf3bd03c36b932b84826a8d9f04e7303 Signed-off-by: MarijnS95 <[email protected]>

The original driver doesn't turn the device off to save power while it's not in use, but careful testing reveals that is properly possible. Resetting the device after powering it causes all kinds of inexplicable side-effects, such as the dreaded error -59 on initial enroll, and the TZ-app requesting another hardware reset when starting an auth or enroll session. Removing this reset fixes all aforementioned issues. The reset has to be done once, when the device is initially powered up.
