crypto: s5p-sss - fix multiplatform build

2014-05-13T11:43:45+00:00

As we are preparing to enable multiplatform support on EXYNOS,
we can no longer include mach/*.h or plat/*.h headers from device
drivers.

The s5p-sss driver was just enabled for EXYNOS when it used to
be used only on s5pv210, and it includes two samsung platform
specific header files for historic reasons. Fortunately, it no
longer actually needs them, so we can remove the #includes and
avoid the problem

crypto: s5p-sss - Look for the next request in the queue

2014-05-08T13:58:15+00:00

Currently, the driver enqueues a request only if the busy bit is
false. And every request initiates a dequeue. If 2 requests arrive
simultaneously, only one of them will be dequeued.

To avoid this senario, we will enqueue the next request irrespective
of the system condition (that is what queue is here for). Also
schedule at a tasklet immediatly after the current request is done.
The tasklet will dequeue the next request in the queue, giving
continuous loop. tasklet will exit if there are no requests in the
queue.

crypto: s5p-sss - Use platform_get_irq() instead of _byname()

2014-05-08T13:58:12+00:00

This patch uses the platform_get_irq() instead of the
platform_get_irq_byname(). Making feeder control interrupt
as resource "0" and hash interrupt as "1".

reasons for this change.
1. Cannot find any Arch which is currently using this driver
2. Samsung Exynos4 and 5 SoCs only use the feeder control interrupt
3. Patches adding support for DT and H/W version are in pipeline
