Tested on silicon, using testmgr. Changes from V4: * Moved clk_prepare_enable for both clocks into the probe function to match the remove function, and avoid inflated prepare/enable counts. Changes from V3: * Standardised the cra_priorities to 300, sufficient to be chosen ahead of software / assembly implementations. * Addressed Andrew Bresticker's review comments, except for two items that I will leave for when I have some more bandwidth if possible as I don't think they are required: ->Runtime PM ->Threaded IRQ handler instead of a tasklet Changes from V2: * This hardware does not support importing a partial hash state, so the init, update, final and finup have been reworked to use a fallback driver; only digest remains as hardware accelerated. * Simplified the driver as a result of the above rework Changes from V1: * Addressed review comments from Andrew Bresticker and Vladimir Zapolskiy * rebased to current linux-next James Hartley (2): This adds support for the Imagination Technologies hash accelerator which provides hardware acceleration for SHA1 SHA224 SHA256 and MD5 hashes. This adds the binding documentation for the Imagination Technologies hash accelerator that provides hardware acceleration for SHA1/SHA224/SHA256/MD5 hashes. This hardware will be present in the upcoming pistachio SoC. .../devicetree/bindings/crypto/img-hash.txt | 27 + drivers/crypto/Kconfig | 14 + drivers/crypto/Makefile | 1 + drivers/crypto/img-hash.c | 1030 ++++++++++++++++++++ 4 files changed, 1072 insertions(+) create mode 100644 Documentation/devicetree/bindings/crypto/img-hash.txt create mode 100644 drivers/crypto/img-hash.c -- 1.7.9.5
