From: "Mark A. Greer" <mgreer@xxxxxxxxxxxxxxx> Changes since v2: - Reworked pm_runtime calls to match where original clk_* calls were so provide better PM (as per Kevin Hilman's comments). 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 v3.7-rc4 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@xxxxxxxxxx:mgreeraz/linux-mag.git wip/crypto/sham-v3+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.
