2012-11-15powerpc+of: Add of node/property notification chain for adds and removesNathan Fontenot
This patch moves the notification chain for updates to the device tree from the powerpc/pseries code to the base OF code. This makes this functionality available to all architectures. Additionally the notification chain is updated to allow notifications for property add/remove/update. To make this work a pointer to a new struct (of_prop_reconfig) is passed to the routines in the notification chain. The of_prop_reconfig property contains a pointer to the node containing the property and a pointer to the property itself. In the case of property updates, the property pointer refers to the new property.

2012-09-05powerpc/crypto: Remove users of virt_to_abs() and phys_to_abs() in nx crypto ↵Michael Ellerman
driver phys_to_abs() is a nop, don't use it. virt_to_abs() is just a wrapper around __pa(), call __pa() directly. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2012-08-20crypto: nx - Remove virt_to_abs() usage in nx-842.cMichael Ellerman
virt_to_abs() is just a wrapper around __pa(), use __pa() directly. We should be including <asm/page.h> to get __pa(). abs_addr.h will be removed shortly so drop that. We were getting of.h via abs_addr.h so we need to include that directly. Having done all that, clean up the ordering of the includes.

2012-08-01powerpc/crypto: add 842 hardware compression driverSeth Jennings
This patch adds the driver for interacting with the 842 compression accelerator on IBM Power7+ systems. The device is a child of the Platform Facilities Option (PFO) and shows up as a child of the IBM VIO bus. The compression/decompression API takes the same arguments as existing compression methods like lzo and deflate. The 842 hardware operates on 4K hardware pages and the driver breaks up input on 4K boundaries to submit it to the hardware accelerator.

2012-08-01powerpc/crypto: rework KconfigSeth Jennings
This patch creates a new submenu for the NX cryptographic hardware accelerator and breaks the NX options into their own Kconfig file under drivers/crypto/nx/Kconfig. This will permit additional NX functionality to be easily and more cleanly added in the future without touching drivers/crypto/Makefile|Kconfig.

2012-08-01crypto: drivers - remove cra_list initializationJussi Kivilinna
Initialization of cra_list is currently mixed, most ciphers initialize this field and most shashes do not. Initialization however is not needed at all since cra_list is initialized/overwritten in __crypto_register_alg() with list_add(). Therefore perform cleanup to remove all unneeded initializations of this field in 'crypto/drivers/'.
