* crypto: caam - set RDB bit in security configuration registerVakul Garg2013-03-222-1/+6
| | | | | | | | | | | | | This change is required for post SEC-5.0 devices which have RNG4. Setting RDB in security configuration register allows CAAM to use the "Random Data Buffer" to be filled by a single request. The Random Data Buffer is large enough for ten packets to get their IVs from a single request. If the Random Data Buffer is not enabled, then each IV causes a separate request, and RNG4 hardware cannot keep up resulting in lower IPSEC throughput if random IVs are used.

| | | | | | | | | | | | | The Kconfig entry for CAAM's hash algorithm implementations has always selected CRYPTO_AHASH. But there's no corresponding Kconfig symbol. It seems it was intended to select CRYPTO_HASH, like other crypto drivers do. That would apparently (indirectly) select CRYPTO_HASH2, which would enable the ahash functionality this driver uses.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OMAP3 and OMAP4/AM33xx versions of the AES crypto module support the CTR algorithm in addition to ECB and CBC that the OMAP2 version of the module supports. So, OMAP2 and OMAP3 share a common register set but OMAP3 supports CTR while OMAP2 doesn't. OMAP4/AM33XX uses a different register set from OMAP2/OMAP3 and also supports CTR. To add this support, use the platform_data introduced in an ealier commit to hold the list of algorithms supported by the current module. The probe routine will use that list to register the correct algorithms.

No new drivers this time, but a bunch of fairly big cleanups: - Roger Quadros worked on a OMAP USBHS and TLL platform data consolidation, OMAP5 support and clock management code cleanup. - The first step of a major sync for the ab8500 driver from Lee Jones. In particular, the debugfs and the sysct interfaces got extended and improved. - Peter Ujfalusi sent a nice patchset for cleaning and fixing the twl-core driver, with a much needed module id lookup code improvement. - The regular wm5102 and arizona cleanups and fixes from Mark Brown. - Laxman Dewangan extended the palmas APIs in order to implement the palmas GPIO and rt drivers. - Laxman also added DT support for the tps65090 driver. - The Intel SCH and ICH drivers got a couple fixes from Aaron Sierra and Darren Hart. - Linus Walleij patchset for the ab8500 driver allowed ab8500 and ab9540 based devices to switch to the new abx500 pin-ctrl driver. - The max8925 now has device tree and irqdomain support thanks to Qing Xu. - The recently added rtsx driver got a few cleanups and fixes for a better card detection code path and now also supports the RTS5227 chipset, thanks to Wei Wang and Roger Tseng." * tag 'mfd-3.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (109 commits) mfd: lpc_ich: Use devres API to allocate private data mfd: lpc_ich: Add Device IDs for Intel Wellsburg PCH mfd: lpc_sch: Accomodate partial population of the MFD devices mfd: da9052-i2c: Staticize da9052_i2c_fix() mfd: syscon: Fix sparse warning mfd: twl-core: Fix kernel panic on boot mfd: rtsx: Fix issue that booting OS with SD card inserted mfd: ab8500: Fix compile error mfd: Add missing GENERIC_HARDIRQS dependecies Documentation: Add docs for max8925 dt mfd: max8925: Add dts mfd: max8925: Support dt for backlight mfd: max8925: Fix onkey driver irq base mfd: max8925: Fix mfd device register failure mfd: max8925: Add irqdomain for dt mfd: vexpress: Allow vexpress-sysreg to self-initialise mfd: rtsx: Support RTS5227 mfd: rtsx: Implement driving adjustment to device-dependent callbacks mfd: vexpress: Add pseudo-GPIO based LEDs mfd: ab8500: Rename ab8500 to abx500 for hwmon driver ...
