From: "Mark A.

Greer" To: linux-omap@vger.kernel.org, linux-arm-kernel@lists.infradead.org Return-path: Sender: linux-omap-owner@vger.kernel.org List-Id: linux-crypto.vger.kernel.org From: "Mark A. Greer" Changes since v3: - Added hwmod support for SIDLEMODE. This requires adding a specific omap_hwmod_sysc_fields structure since there are not generic ones that have the correct offsets. - Added patch to remove the cpu check from the omap-sham driver. This can likely be ignored since there is a patch that already does this in Tony's branch. I added it to make it easier for others to test while Tony's patch makes its way to the k.o. 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 3587b1b (fanotify: fix FAN_Q_OVERFLOW case of fanotify_read()). 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@github.com: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.
