Hi All ,
As per my understanding backlogs are used when crypto hardware
processing a request ,then multiple incoming requests comes to serve .
A queue/backlog is created to enqueue the request .Please let me know
if my understanding is incorrect.
EX:
M4,M3,M2,M1 > H(M0)
Here H(M0) under pro
Register crypto hwmod links only if they are not disabled in DT.
If DT information is missing, enable them only for GP devices.
Before this patch crypto hwmod links were always disabled for all HS devices
and it was not possible to use omap-aes and omap-sham linux drivers.

omap3 support is same as omap2, just with different IO address (specified in DT)

This patch series fix crypto support for omap3 devices which use DT.
It enables AES and SHAM on N9/N950 and SHAM on N900. AES is still disabled for
N900.

Without this patch function pm_runtime_get_sync() returns 0 even when some
omap subfunction fails. This patch properly propagate error codes from omap
functions back to caller.
This patch fix problem, when loading omap-aes driver in qemu cause kernel oops.

Device timer12 is automatically disabled on all HS devices via DTS property
"ti,timer-secure" in file omap3.dtsi so it can be safely removed. We do not
need to disable it on another place.

This patch just move content of file omap34xx-hs.dtsi into omap3-tao3530.dts.
There is no code change, patch is just preparation for removing -hs file.

This patch adds missing dma DTS definitions for omap aes and sham drivers.
Without it kernel drivers do not work.

This patch moves content of file omap34xx-hs.dtsi into omap3-n900.dts and enable
omap sham support (omap HW support for SHA + MD5). After testing both omap hwmod
and omap-sham.ko drivers it looks like signed Nokia X-Loader enable L3 firewall
for omap sham. There is no kernel crash with both officia
Harmattan system on Nokia N9 and N950 devices uses omap crypto support.
Bootloader on those devices is known that it enables HW crypto support.
This patch just include omap36xx.dtsi directly, so aes and sham is enabled.
