* crypto: add i.MX6 CAAM supportSteffen Trumtrar2016-02-1217-0/+4638
| | | | | | | | | | | | | | | | Add the i.MX6 crypto core CAAM with support for the random number generator. The core itself works with jobrings in which descriptors can be queued/dequeued for processing. Depending on descriptor type the CAAM unit then either produces random numbers or decrypts/encrypts data. The code is based on the Linux v4.1 driver of the same name without all the crypto/hashing components.

* driver: Fix unregister device after device probe failureSascha Hauer2016-02-081-0/+4
| | | | | | | | | When a device probe fails the device is removed from the active list. If then the device is unregistered afterwards it is removed from the active list again resulting in a crash. To fix this initialize the devices active list entry when removing it from the active list. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on kernel commit d2fd719bcb0e ("net/phy: micrel: Add workaround for bad autoneg") by Nathan Sullivan <nathan.sullivan@ni.com>: Very rarely, the KSZ9031 will appear to complete autonegotiation, but will drop all traffic afterwards.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently all input driver register themselves as consoles. Consoles are fine for typing text, but they do not allow to ask for the current pressed state of buttons or keypads. They also do not support non printable keys like the function keys. This patch adds a simple input core. On the driver side it supports input_report_key_event() to report events (button presses and releases). On the consumer side it allows getting the current button status via input_key_get_status(). Also an event driven interface is available which calls a callback whenever an input event is received. The input core also registers a console for all registered input devices which handles passing events to the console and stuff like key repetition, so this can be removed from the drivers once they are converted to the input core.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The HABv4 functions need access a part of the ROM which is located in the zero page. This must be done early, before the MMU has been configured and the zero page has been set to faulting. The HAB functions currently use cpu_is_imxxy(). At the stage where HAB is called the i.MX CPU type variable is not yet initialized, so this code only works when only one i.MX type is enabled and cpu_is_imxxy() are compile time constants. To fix HAB support when more than one i.MX type is enabled make the HAB status function SoC specific so that we can drop the use of cpu_is_imxxy().
