From: "Mark A. Greer" <mgreer at animalcreek.com>
Changes since v1:
- Removed the check of CM_IDLEST to see if the module exists
and instead add the hwmod data for all omap2's and omap3 GP's.
- Placed new sha_ick clk entries after the 'omap-sham' entry
in the clockxxx_data.c files
- Removed cpu_is_xxx() checks in
arch/arm/mach-omap2/devices.c:omap_init_sham()
- Rebased on the latest k.o. kernel
This series updates the crypto omap-sham driver and supporting
infrastructure.
Notes:
a) Based on current k.o. 2d1f4c8 (Merge branch 'drm-fixes' of
git://people.freedesktop.org/~airlied/linux)
b) Since these patches will likely go though the OMAP tree (and not
through the crypto tree), it would be nice if the crypto guy(s)
would ACK or NACK patches 5-7 which modify the
drivers/crypto/omap-sham.c driver.
c) These have only been tested on an omap2420 h4 and an am37x evm. If you
have different hardware available and a few minutes, please test them.
A quick and easy test is to enable tcrypt as a module
(CONFIG_CRYPTO_TEST=m), boot, then run 'modprobe tcrypt sec=2 mode=403'.
'CONFIG_CRYPTO_SHA1' and 'CONFIG_CRYPTO_DEV_OMAP_SHAM' also have to be
enabled. A quick 'grep omap-sham /proc/interrupts' will tell you if
the omap-sham driver was really used.
d) To test these patches, you will likely need...
i) The patch included here:
http://marc.info/?l=kernel-janitors&m=134910841909057&w=2
ii) This patch from linux-omap/master:
27615a9 (ARM: OMAP: Trivial driver changes to remove include
plat/cpu.h)
iii) This patch from Paul Walmsley:
http://www.spinics.net/lists/linux-omap/msg79436.html
e) If you prefer, a version you can test is available at
git at github.com:mgreeraz/linux-mag.git mag/wip/crypto/test
f) There is a reduction in DMA performance after switching to dmaengine
(see http://www.spinics.net/lists/linux-omap/msg79855.html)
g) Many thanks to Jon Hunter for testing on his omap2420 h4.
